Consider this.. (cont.) Doing the math.

This post/essay is more than 3,600 words.

THIS SERIES of essay-length posts is prompted by questions about the form of one sharp, angular glyph resembling the modern short-stemmed ‘4’. Our paradigmatic example being:

This post outlines the communities and inter-connections between them over time which would finally see emerge the same ‘4’ shape numeral and other matter whose reflection is found in our present, fifteenth-century manuscript with its many unusual features.

In the instance seen above, the long bar above it makes it easy to interpret the glyph as alphabetic, and so take this pair as abbreviating some such word as q[u]o – yet the glyph’s form is not written as a Latin ‘q’ of the early fifteenth-century and allows us to suggest that even if, here, the ‘4’ glyph wasn’t intended for the numeral ‘4’, it has been written by a hand accustomed to writing the numeral in that way.

Before 1440 ‘four’ represented by this shape was still uncommon – unattested (to date) in Germany before the Voynich manuscript was made (1400-c.1440), and rare;y in England. Thus, so far, we must attribute it to the south-western Mediterranean and to the communities having attested ties to Majorca at the time our earliest clear example of the ‘4’ numeral occurs there (1375 AD).

The following passage, appended as a comment to the previous post, deserves greater prominence.

“James I appears to have chosen Majorca as his first target because of the island’s geographical importance and its closeness to the Spanish coast. Almost equidistant from Catalonia, the north of Africa, and Sardinia, the island’s ports dominated the trade routes of the western Mediterranean. James’s army included … large numbers of townspeople from the main trading cities of Catalonia and southern France, especially Barcelona, Marseilles, and Montpellier. Unlike the barons …many townspeople actually settled in Majorca and contributed to its prosperity. Some of the settlers came from further afield. While Catalans were the most numerous, there were also Aragonese, Navarrese, men from southern France, Italians (from Naples, Sicily, Genoa, and Pisa), Castilians, and Portuguese. In addition to the conquered Muslims, there was also an important Jewish community in Majorca from very shortly after the Christian conquest of 1229. This community had ties not only to Catalonia and southern France, from which many of its members had come, but also to north Africa, and Italy.” (p.335)

  • passage from J.N. Hilgarth, ‘Sources for the History of the Jews of Majorca’, Traditio, Vol. 50 (1995) pp.334-341, though other recent sources will include the same information.

To do a reality-check here – to ensure we’re not straying too far from evidence and veering from historical research into merely hunting support for a theory – we now test our present emphasis on the south-western Mediterranean against earlier informed opinion about Beinecke MS 408.

The set of connections exemplified by the Majorcan population accords with Erwin Panofsky’s attributing the manuscript -or perhaps something about its vellum and style of drawing – to ‘Spain or somewhere southern, with Arab and Jewish influence’ and shows there need be no opposition supposed with the consensus opinion of specialists in manuscript studies who were known to H.P. Kraus and his assistant Hellmut Lehmann-Haupt in the 1960s – their focus having been clearly on Italians.* Again, the month-names’ orthography has been variously described as Occitan (also spoken in Genoa), and as Judeo-Catalan, and so forth. (These things have been treated as separate issues in earlier posts. For a list, with links, see Table of Contents page in the top bar.)

*The views relayed to John Tiltman by Lehmann-Haupt, research assistant to the bookseller H.P. Kraus, are recorded by Mary d’Imperio, Elegant Enigma p.7 and 8).

Checking, again, if the class of text early using ‘4’ numerals is appropriately described as practical, navigational and/or commercial, those parameters easily present us with another instance prior to 1440.

That detail comes from manuscript known as the ‘Handbook of Michael of Rhodes’. It is in private hands but has been studied and summaries of the study are online.

  • Michael of Rhodes’ book website (here).

Michael’s education was gained as a mariner, his education by apprenticeship and in keeping with ‘tradesmans’ mathematics taught by schools of the kind known to the Italians as ‘abaco’ or ‘calculation’ schools. He began writing an account of his life and nautical-commercial calculations in 1434, his year of death being 1445. (see pages at the Galileo Institute site). As one might predict, he served one of the Italian maritime city-states – Venice.

Appropriately enough, his example for that calculation (partly illustrated above), is about the purchase of pepper – obtained by Venetians of his time from Alexandria or Tunis, but which had been traded since Roman times (at least) into the Mediterranean via Egypt from commercial pepper plantations in southern India. Alexandria remained a principal centre of that trade in Michael’s time, with Tunis, though in the earlier medieval period, the carriage of eastern products to Christian Europe had been principally in the hands of Jews and others classed and taxed as Jews in areas under Muslim governance.

Such links with Egypt and exotic goods naturally again reminds us that Georg Baresch believed the manuscript’s content had been gained ‘in the east’ and contained matter that was – in some sense unspecified – both Egyptian and ‘ancient’. He also said that the plant-pictures referred to ‘exotics’ whose forms were still unknown to German botanists in his time, when Germans led all Europe in that field.

My study of Beinecke MS 408 also found much to support Baresch’s opinion about the plant-pictures.. but presently we are not concerned with meaning so much as with forms – the form of the written text, of the pictorial text and the manuscript’s presentation.

On that basis, we may lay aside (pending possibly better information) such Voynich theories as the ‘Norwegian’ or the ‘central European’ or the ‘New World’ theories, which offer no comparison for the ‘4’ shaped glyph, or for the apparently anomalous ‘gallows glyphs’ with their elongated ascenders (if that’s what they are), nor comparable styles of script, drawing, page-layout or -disposition, nor the presence in any such manuscript noted so far of quires both quinion and septenion as we do see in the Voynich manuscript and have also found in Italy and in Hebrew manuscripts from the south-western Mediterranean – on paper, on membrane and in a combination of both (see earlier posts).

Even within Italy, it seems at present that perhaps we should discount the higher levels of education and of society, since the only instance of a ‘4’ shape which might be associated with nobility or bureaucracy known so far, is in one cipher-ledger from Urbino dated to 1440, brought to notice by Nick Pelling in 2006. But 1440 is sixty-five years (nearly three generations) after our earliest clear instance of that ‘4’ in Abraham Cresques’ Majorcan ‘Atlas’ of 1375 and almost a century and a half after one brief appearance in Florence, in a copy of the Liber abaci.*

*The bankers of Florence were strongly opposed to use of the Hindu-Arabic numerals, attempting and succeeding for a time in blocking their use.  I don’t have an English-language source for this, but see  Anna Maria Busse Berger,Lada Hordynsky-Caillat and Odile Redon, ‘Notation Mensuraliste et Autres Systèmes de Mesure au XIVe Siècle, Médiévales, No. 32 (Spring, 1977), pp. 31-46 and particularly p. 34. [JSTOR]

On the other hand, while the written text’s inclusion of that ‘4’ glyph in Beinecke MS 408 directs our attention to the commercial and maritime interests of communities whose people are found settled in thirteenth- and fourteenth-century Majorca, including those maintaining ties with Italian cities, it is Panofsky’s “Spain or somewhere southern” which is given clearest support by content in our fifteenth-century document.

When I cited the Codex Vigilanus among examples explaining the Voynich pages’ page layout and dispositions, I found no previous allusion to it in any ‘Voynich’ writing though I should not be surprised to find it mentioned elsewhere today.

It crops up again now because the same manuscript is referenced in Hill’s Tables and in the review of Hill’s work by Louis C. Karpinski, who was at that time (1915) the foremost scholar interested in the history of European forms for the numerals.

As introduction and context for quoting from Karpinski’s review, I’ll reproduce a paragraph from one earlier post from voynichimagery. In it, I was making the point that the Voynich page design, especially but not only in the ‘bathy-‘ section, differs markedly from the consciously ‘Greek and antique’ simplicity of Italian ‘humanist’ manuscripts, yet it finds echoes in other times and places, including tenth-century Spain.

.. another example. This from Spain, in a volume containing material of the the 9th-10th centuries. Notice how these illuminations fill the sides of the page, and how the text seems to be fitted around the central figure, a little irregularly, as if the imagery had been set first, and the text written later – the very opposite method from that used in manuscripts from most of Latin Europe, but this was in Spain, under Muslim rule – though the degree of influence from Baghdad as against that of the Berbers from North Africa is debated along sectarian lines. However, that non-Latin character in contemporary Spain may explain the way these pages are planned, uncharacteristic of Latin texts per se, despite the language in which it is written. … these pages’ design offers points of comparison with MS Beinecke 408. Most particularly, in my opinion, with the ‘bathy-‘ section, which [because of anthropoform ‘ladies’] implies again connection with the [month diagram] foldouts … Note here, once again, that same convention [seen in Yale, Beinecke MS 408] of using roughly-parallel curved lines to denote curve and volume. … [and the makers’ familiarity with the ‘false-bearded’ face and the concept of a bicorporate form, all of which occur in Beinecke MS 408 –  D.]

Having previously cited that codex, it was pleasant to find it referenced by Hill and commented on by Karpinski, who said,

The earliest European forms are doubtless found in the Codex Vigilanus, written in 976 AD in the monastery of Albelda near Logrono in Spain. A second Spanish manuscript of about the same date, not described by Mr. Hill, also contains similar forms, and facsimiles. Both are to appear in the next issue of Professor John M. Burnam’s Palaeographia iberica.

from: ‘The Development of the Arabic Numerals in Europe Exhibited in Sixty-four Tables. by G. F. Hill. Reviewed by  Louis C. Karpinski’ for The American Mathematical Monthly,  Vol. 22, No. 10 (Dec., 1915), pp. 336-337.

Hill’s reference to the Codex Vigilanus was a note to his Table 1: 

1. 976. Escorial d I 2. Codex Vigilanus, written in the year 976 in the monastery of Albelda near Logrotio. See P. Ewald, Neues Arcbiv der Gesellsch. /. alt. deutsche Geschichtskunde, viii (1883), p. 357. Cp. Smith and Karpinski, p. 138. The forms are described as the Indian figures, quibus designant unumquemque gradum cuiuslibet gradus. Quarum hec sunt t”orm(e): 987654331. Ewald connects the form for 5 with the Roman V. Since he does not say that the year 976 is that of the Spanish era, we must assume that it is of the usual Christian era.

I have not sighted Burnam’s Palaeographica iberica.

Already, by the tenth century, mathematical studies were advancing within Spain as in North Africa. While few scholars consider any matter in terms of Christian, Jewish and Muslim scholarship altogether, the separate studies of western numerals and mathematics have, independently, commented on the situation in tenth-century Spain. It was from there that – for example – Gebert d’Aurillac was said to have learned his calculating ‘arts’* though I suspect that his original ‘abacus’ with its significant factors – 9 and 27**– is less related to that form later given his name than to something he first encountered during the period when Barbary pirates had him.

*D.E. Smith. A History of Mathematics (Vol.2, p.75) says ‘there is good reason for thinking Gebert’s knowledge of the numerals was gained in Ripol, at the convent of Santa Maria de Ripol.

**the ‘9 and 27’ are rarely mentioned in secondary accounts today. I have no English-language reference for it to hand, but see the review of O. Chasles, ‘Histoire de l’arithmétique. Explication des traités de l’Abacus, et particulièrement du traité de Gerbert; Extrait des comptes rendus des séances de l’Académie des sciences’, Reviewed by H.G. in Bibliothèque de l’École des chartes, Vol. 4 (1842-1843), pp. 382-386.

But that’s by the way.

With regard to the Maghrib, I quote from Ahmad Djebbar’s studies, which do show that we do better to focus on lines of connection over time and distance, than defining matters in terms of a static parochial ‘nationality’.

Abū ‘l-Qāsim al-Qurashī … was a native of Seville, in Spain, spent a period of his life in Bougie (Béjaïa) where he died in 1184. The biographers who evoked him consider him a specialist in Algebra … [in which subject] al-Qurashī is known for his commentary on the book of the great Egyptian mathematician Abū Kāmil (d. 930). This commentary has not yet been recovered but its importance is confirmed by the historian Ibn Khaldūn (d. 1406) who considered it one of the best treati[s]es written on the book of Abū Kāmil.

Djebbar does not consider the works of Christian or of Jewish scholars relevant to his study, yet traces the evolution of mathematical studies in the Maghrib to Kairouan, which had been a community of unusually ascetic Jews until mention of them and of Kairouan in a narrative known as the ‘Night Journey’ linked Kairouan directly to the Prophet of Islam, reverence for whom saw the town declared a holy place and the original inhabitants expelled.*

*In this connection, I’d mention that D.E. Smith (op.cit., loc.cit.) says the names given the Ghobar numerals in the earliest Latin texts are: igin, andras, ormis, arbas, quimas, calctis, zenis, temenias, celentis and sipos, which Smith says appear to be Semitic. 

By the tenth century there were remarkable Jewish scholars working from the region presently of interest to us, but before considering one Jewish mathematician of the fourteenth century – that is, one who lived at the time we see the early emergence of that ‘4’ shape, it will be as well to pause again to check our bearings.

So far, it appears that what we have as the content in Beinecke MS 408 may be – again to quote Panofsky – “considerably earlier” matter within the material which was copied to provide the quires of our present fifteenth-century manuscript, and if the copies were not inscribed within Italy itself (as is possible), I think that by considering other matter in the manuscript we may posit with some confidence that the material as we now have it was copied for an Italian sponsor – whether Christian or Jew – during the period 1400-c.1440.

It is also possible that the manuscript’s written part, being added to the page after the pictorial text in a custom contrary to that of mainstream Latins’ work, may have taken its form as ‘Voynichese’ not much earlier than our present copy and thus to require study within parameters different from most of the imagery in which so few details express the Latins’ worldview iand so much speaks to earlier and other customs.

A relatively late creation of the ‘Voynichese’ script offers us one reasonable explanation for the apparent discrepancy between (i) disposition of image and text, and primacy given image over text, against (ii) the scribes’ evident familiarity with a straight and short-stemmed ‘4’ form characteristic of western works from the fourteenth century and later, whether that form is used here as alphabetic or numeric. Of course, that is not the only possible explanation we could call reasonable. We have yet to consider scripts from other parts of the greater Mediterranean (let alone the world) in which a ‘4’ form occurs.

Yet Spain and the example of the Codex Vigilanus allows us at least to suggest that the earlier models might date from as early as the time when ‘elongated ascenders’ still appear in such documents as the Papal charter establishing the convent of Ripol.

The fact is that we can’t be certain, at this stage of investigation, that the Voynich ‘gallows glyphs’ do have their form such ‘elongated ascenders’.

They might – for example – imitate scribal conventions from some other language altogether. I expect that there were some readers who sat up on seeing one not-quite-match between the form of a Voynich ‘gallows glyph’ and a Greek form in that detail from Codex Vatopedinus 655 which is in the previous post.

Prague

A letter whose chief theme was the lamentable decline of mathematical studies among the Jesuit scholars of Prague was sent to Athanasius Kircher in 1667 from Aloysius Kinner, about six months after the Voynich manuscript had been sent from Prague to Kircher in Rome.

Kinner refers to the manuscript and to Marcus Marci, on whose behalf the manuscript had been sent.

Marci had included with it a covering letter whose final paragraph reported, but declined to endorse, a rumour that – as Marci recalled it – was told to him several decades before, and – as he remembered it – by Rafel Mnishovsky. Evidently sent in 1666 (though dated August 1665) that paragraph in Marci’s letter remains the sole basis for any alleged connection between the manuscript and Rudolf II.

In January of 1667, then, Kinner writes in connection with mathematics:

Our own Marcus, so widely known for his writings in mathematics and other studies has now fallen into the second infancy of old age. He barely understands everyday necessities, as I note with much sadness and distress whenever I happen to visit him…. Now these men are gone scarcely any are left who could be called mathematicians and those few are totally occupied with other studies and are obliged to sneak their glances at mathematics….There is a deep silence, not to say ban, on Euclid and Appollonius in this university so that we are now not even supposed to know the names let alone the thing….And now for other matters. Dominus Marcus has lost his memory of nearly everything but still remembers you. He very officially bids me salute you in his name and he wishes to know through me whether you have yet proved an Oedipus in solving that book which he sent via the Father Provincial last year and what mysteries you think it may contain. It will be a great solace to him if you are able to satisfy his curiosity on this point….I do not know whether you are interested in having your Organum Mathematicum which you once prepared for our Archduke Carolus…

It only remains, now, to compensate a little for the habit of historians of ‘parochializing’ specific studies. I’ll mention just one medieval Jewish mathematician – Immanuel ben Jacob Bonfils (c. 1300 – 1377).

In 1936 an optimistic George Sarton wrote,

It is extremely interesting that the streams of thought which led eventually to decimal calculations on the one hand and to exponential calculations and logarithms on the other, had apparently two main sources, a Christian one and a Jewish one – both being ultimately derived from the same Greco-Arabic fountain head.. Gandz and I have now placed him [Bonfils] – and forever- among the great mathematicians of the fourteenth century, in the company of Oresme and John of Meurs. Henceforth the city of Tarascon should not remind us only of the famous Tartarin but also of one of the great mathematicians of the Middle Ages, the Provencal Jew, Immanuel ben Jacob Bonfils.

The remarks speak of Sarton’s acquiring a photostat copy of BNF Hebrew Ms IO54.6 and Gandz’ translation of the text (‘Derek (i) hilluq’). Gandz’ prefatory remarks, outlining earlier errors of the text’s description and interpretation incidentally offer another good example of that complex mix of forward and backward movement by which an historical study so often proceeds.

On the mathematical text, Gandz writes:

The invention of Bonfils introduces two new elements: the decimal fractions and the exponential calculus. In the latter case he substitutes the addition and subtraction of the exponents, or of the denominators of the degrees, as Bonfils calls them, for the multiplication and the division of the decimal powers. Our impression is that Bonfils is primarily interested in the demonstration of this method of the exponential calculus.

As you’ll see by consulting wiki articles about Algebra or Calculus, Sarton’s confidence was misplaced. We are yet to see Bonfil’s role properly acknowledged in mainstream narratives.

Abstract:

Part A treats of the ‘bearded sun’; of a ‘sun of night’ in eleventh-century Burgos; and of the regular passage of persons, goods and information back and forth across the Mediterranean during the medieval centuries. It is far from inconceivable that the material now in Beinecke MS 408 might have been collected in ‘eastern parts’ including medieval Egypt and contain (as Baresch also said) pictures of plants not native to Europe.

Part B considers earlier Latin attitudes to the stars, and another eleventh century manuscript – one made in northern France. It is the first known Latin copy of the astrological work, Liber Alchandri.  In the margin of one folio two very large green stars were placed, apparently by the copyists’ overseer. 

This is another post that includes enough material for three or four. I regret being unable to make editorial comment optional, collapsed text. 

PART A

A diagram on folio 67v has at its centre the face of a woman or of a young man that is provided with artificial hair and beard, and with eyes unfocused, surrounded by stars apparently disposed in seventeen unequal sectors. (see previous post)

(detail) Yale, Beinecke MS 408 f.67v. The image is clearly not classical Egyptian but accords with Hellenistic forms. Sekhmet’s leonine character was not so popular in Ptolemaic Egypt as formerly she had been.
amulet – Egypt. bearded, feline, Sekhmet daughter of Re’. wife of Ptah, guardian of boundaries. Regularly portrayed with sun-disk and uraeus in older Egyptian art.

Comparable forms for an artificially-bearded sun are attested from the eastern side of the Mediterranean – first in artefacts from pre-Christian Egypt, Syria and Mesopotamia. The oldest show a leonine female (Sekhmet) termed ‘daughter of the sun’ who was typically shown with the sun-disk and serpentine uraeus. The word for sun takes male gender in the Egyptian language as it does in Greek and Latin, the image on folio 67v nicely ambivalent creating a ‘universal’ form. Its having a human face points to origins in a Hellenistic- rather than a Pharaonic environment, I should think.

As to the sun’s gender, that varies with language. Some languages have it female, and among those, some – including Hebrew – allow its description as male or as female, though as not both at once. The image on folio 67v is not alchemy’s rebis.

We have some reason* to believe that matter now in the Voynich manuscript may have been copied from materials collected in “eastern parts” though the Voynich manuscript itself was made in the earlier part of the fifteenth century and is reasonably thought to have been made in Europe.

*Letter of Georg Baresch to Athanasius Kircher (1639)

Sekhmet as mistress of mariners. A statue now in Genoa.

Since the sun-face on folio 67v with its artificial mane and serpentine sidelocks is plainly no Christian helios but does shows this sun-face surrounded by stars, one must ask how the fifteenth-century copyist, or the person for whom the manuscript was being copied, might have understood this motif and the diagram’s purpose.

 

First – is any other sun-of-night attested in medieval western Europe and if so, when and where? The answer is ‘yes’ – but rarely and in the earlier medieval period – that is, before the twelfth century. It was not envisaged by the Latins as female.

Sun of Night’ in medieval Spain.

Among several examples noticed and translated by Carey, one comes from an eleventh-century manuscript produced in  Silos abbey of Burgos. It uses the instructional mode:

Tell me: does the sun shine at night, or not?It does.

Tell me: in what way? – For three hours in the abyss, for three hours in the sea, for three hours in the city of Nataleon, and for three hours in the city of Jerusalem. Then it returns to the east [i.e. the point of sunrise on the western viewer’s horizon] in the first hour of the day, and shines for the twelve hours of the day, and returns into the west.

  • John Carey, ‘The Sun’s Night Journey: A Pharaonic Image in Medieval Ireland’, Journal of the Warburg and Courtauld Institutes, Vol. 57 (1994), pp. 14-34. Carey does not provide full details of the manuscript. It may be the Silos Apocalypse but I’ve not been able to verify.

Carey does not mention it, but the four stages may be equated with the four elements – abyss (air); sea (water); nataleon (fire – by association with the lion); Jersualem (earth as foundation). 

Transmission and exchange across the Mediterranean.

Given that our clearest extant example of the artificially-bearded sun is in an ivory attributed to Phoenicians and some Phoenician cities in the western Mediterranean were as much as seven hundred years old before the rise of Rome, so we do not necessarily have to pass very far from Burgos to find the source of ideas and images akin to those in folio 67v.

  • Gerard Gertoux, Dating the Foundation of Carthage’ (paper at academia.edu)

 On the other hand, Baresh’s letter seems to demand that we do, so I include the  following broad-brush overview as editorial, not least to serve as counterweight for the now traditionally-Eurocentric narratives created for the Voynich manuscript, almost all being derived from that which Wilfrid Voynich forged from no more than a signature in the manuscript and a rag of unsubstantiated, third-hand hearsay.  Though rarely questioned, the Mnishovsky rumour is certainly questionable historical evidence. Assertions such as that the manuscript is ‘known’ to have been in Rudolf’s library, or that Rudolf ‘bequeathed’ it to anyone are due to more recent writers’  historical imagination.

In the following editorial comment, I mean to emphasise that by present standards, the old assumptions of a western Europe unaffected by any unsolicited ‘foreign’ matter can no longer be maintained.  In the nineteenth and earlier twentieth centuries which were the formative years for those first involved with the manuscript, it was imagined that no non-Latin matter entered the western Christian (‘Latin’ European) intellectual horizons except it were deliberately chosen and  – as it were – passed  the rigors of  ‘customs inspection’,  monitored transition, ideological cleansing and subsequent naturalisation. The stories of Leonard of Pisa (Fibonacci), Gerard of Cremona etc. serve as paradigm for that idea of a ‘white-walled’ Europe. 

An idea that nothing could arrive in Europe but what been ‘passed’ does apply, to an extent, to the Latins’  ‘bookish’ tradition, but the Voynich manuscript offers much in its internal evidence, and of course Baresch’s letter to Athanasius Kircher adds more, which should have led more researchers than John Tiltman or Erwin Panofsky to doubt the story created by Wilfrid with William Romaine Newbold. 
Europe’s Christianity was scarcely well rooted before the time of Columbanus and his fellows, but Irish monasticism in turn had its source and model in earlier Egyptian monasticism, and with it their liturgical calendar and computus, their tradition of copying older manuscripts and, tellingly, their dissemination and use of that extraordinary work, The Marriage of Mercury and Philology in which- by the way –  the ‘number of the sun’ is explicable only by reference to the old Boharic Egyptian-Coptic dialect.
  • Leslie S. B. MacCoull, ‘Coptica in Martianus Capella De Nuptiis 2.193’, Classical Philology , Oct., 1995, Vol. 90, No. 4 (Oct., 1995), pp. 361-366.
In northern Italy, the monastery of Bobbio (in whose library Gerbert of Aurillac would later say he found a copy of Manilius’ Astronomica) was founded and its library first furnished by the Irish Columbanus. Similarly  St.Gallen was founded one of Columbanus’ fellows and it  oldest manuscripts too were copied by Irish peripatetic scribes.
Egyptian life and traditions did not vanish at the moment when Caesar first set foot on Egyptian soil, nor when the last Pharaoh died, though some Voynich writers have supposed it so, dismissing Baresch’s comments from that erroneous belief.   Not until the third century AD were Egyptian temples closed by Roman edict, and many still stood in the 7thC AD.  The role of liturgical Coptic in assisting our understanding of the older Egyptian language and script is now well known, and as Baresch’s letter to Kircher shows, it was in response to Kircher’s appeal for material to help decipher hieroglyphics that Baresch sent the copied sections.  Regardless of indications in the imagery, however, results of numerous statistical studies of Voynichese have not suggested derivation from any Egyptian dialect, or any other language as it was spoken and/or written in Egypt.  The matter in the manuscript may have been gained ‘in the east’ but that is not reason enough to presume the same is true for the present manuscript’s written text.
  • Alan K. Bowman, Egypt after the Pharaohs 332BC-AD642. (1986).
Throughout the medieval centuries, however, Egypt continued to be a major entrepot though which  Mediterranean traders and pilgrims passed constantly during the sailing year from the beginning of Spring until October-November and, occasionally locally, December. 
In twelfth-century  Exeter, for example, evidence of direct free contact is offered by some of the misericords’ carvings.  Those are not ‘official’ carvings, but a space which the workers might ornament ad.lib. That shown (below) accurately represents a pair of Egyptian ‘ba’ birds, both in their form and still more strikingly, with their original significance.  For these two ‘souls’ he almost got the forms perfect. (I regret not being able to show here a facing pair from Karnak).  The most interesting point is that so late as the mid-thirteenth century someone – some guide, presumably – had still been able to rightly explain the sense of the originals. Exeter06.3 ba birds
Though the ‘ba’ bird usually stood on bird-feet, where these are provided hands, it is an understandable mis-reading if (as I suspect) he’d seen high above him and foreshortened, the pair at Karnak.  He certainly meant to make the  faces European, and one must wonder whether these ‘soul-mates’ are the woodcarver and his wife.
Europeans in medieval ports and markets had little difficulty with language.  As one mid-fourteenth century traveller describes: 
If you ask how I could converse with the interpreter .. the interpreter is of Jewish descent and came to Misr [Egypt/old Cairo] to return to Judaism, because he is a Spaniard..

Venice and Genoa had more than one fondak  assigned exclusively for their use at various times, though free access to Egypt fluctuated with changing political tides. Practical reasons for travel included the chance to buy cheaply in the east what might be sold at greater price in the west – such things as Indian gems, Chinese silk and plant-products whose ultimate source was India and south-east Asia.  
Studies of the Latin, Greek and Arabic antidotaries tell us, for example, that a trade in eastern plants was maintained – not directly, but via Cairo or some other eastern centre –  from southeast Asia to as far as England before the twelfth century. One of the first to engage with that topic was John Riddle. Today there is a great body of scholarship available for study of medieval pharmacy, antidotaries and related trades, but in 1965 Riddle could speak of,
a manual for traders, composed possibly in the 11th century or even earlier, lists ambergris along with camphor, musk, aloes, pepper, cinnamon, and ginger.
and e.g. that
The word cafora, coming from the Arabic kâfôur, is found in the same manuscript as ambergris and also in an antidotary written in Lombardie script in the 9th or 10th centuries. As a product of the plant cinnamomum camphora nees, cafora or camphor is found only in the orient.

Note – I have tried as far as possible throughout all these posts to cite articles accessible through libraries and online outlets such as researchgate, JSTOR and academia.edu.  I’ve selected them not only for the article’s content, but the value of an author’s sources and bibliography to assist in further research. In some cases this was simply not possible and I’ve had to cite the works used i my own research, some of which I know only the keenest researcher would care to hunt out, but the necessary information is nowhere else.  

Altogether, it is now clear that ideas prevalent in the nineteenth century and which Friedman, or d’Imperio took as ‘givens’ into the post-WWII period, were badly skewed.   Medieval Europe lived in no cultural ‘bubble’. The monks and secular scholars who made Europe’s ‘bookish’ history and textual traditions did, it is true, become increasingly skittish over time about having ideas they thought contrary to western Christian doctrine brought west by foreign residents and by such groups as the Italian humanists. The less able the authorities were to ignore  or to control such  information, the more savage their efforts became to ensure it was not disseminated through the western Christian populace without being provided a western Christian commentary and interpretation.  But these efforts were long limited to the more highly educated class, no effort made during the earlier medieval period to monitor the activities of traders, incoming travellers, or minority non-Christian communities. If a text was neither in Latin nor (later) widely circulated in the vernacular, it could be ignored.

The practice of just ignoring ‘foreign’ material saw some sad losses to European learning, and it is surprising to see how much valuable information was ignored.  As one example, we may refer to Idrisi’s radically new astronomical-geography completed after all most two decades’ work, in Sicily, in 1154, at least one copy having been prepared in a Latin translation, but we find no interest in it ever shown by Latin Europe for almost five hundred years – not until a copy of the Arabic text was published in Rome in 1592 by the Medici Press

 Idrisi did not simply copy or update  Ptolemy’s data, Over nineteen years, Idrisi had permission to interview any of the myriad travellers, traders and pilgrims who, perforce, called in at Sicily during their east-west journeys.
The result was a new astronomy as well as a new geography and,  using both in tandem, it described the world from China to Britain, region by region. Some of Michael Scot’s work is thought to have depended on Idrisi’s astronomical information. 
Perhaps the Latins (i.e. western European Christians) rejected it because they disapproved of Roger’s multi-cultural ‘international’ court. Perhaps it was one of those times when Roger was under ban of excommunication. Perhaps it was because Idrisi used south (the direction of the Latins’ Hell) as his primary direction.  Perhaps because the real world didn’t display a neat tripartite division reflecting the Biblical assignment to one part to each of Noah’s sons.  Who knows?  Here’s a reconstruction of Idrisi’s south-oriented world-map. 
For a  ‘north-up’ view, see here
Idirisi world map
The people who brought ‘caphora’ to Cairo, or to north Africa, or to Lombardy didn’t need a map of this sort, nor a handbook of geography to do it.

To further illustrate the range over which the  ‘Sun of night’ had been accepted in the older near east, I’ll mention the Babylonian version, too and Europe does acknowledge a passive debt to Babylonia in mathematical astronomy.

PART B.

Having found mention of a ‘sun of night’ in eleventh-century Burgos (see above), we may now  consider another manuscript of that period, this one made in northern France (Brit.Lib. MS 17808).  To understand how its material was viewed at that time, we must better appreciate how Latins thought about the stars in those days, and how they regarded mathematical calculations.  

By the eleventh century, the two greatest voices in Latin Christianity were those of the north African, Augustine, and that of Isidore of Seville.

Augustine (354 – 430 AD) had been of Phoenician parentage, had a passion for studying the stars (in a combined astronomy-and-astrology), then became attracted to the original form of Manichaeism, at that time  one of the major world religions and which by the tenth century was established to as far as the borders of China. Along those eastern roads, it was a major provider of centres for traders and travellers –  groups largely associated with the spread of that religion.  In north Africa, however, Augustine had eventually abandoned his early interests, converted to Latin Christianity and through his writings become one of western Christianity’s earliest and most revered theologians.

With regard to astronomical learning, and the seeking of  wisdom from Egypt, I might also mention Gregory the Great (540 – 604 AD), author of the ‘Commentary on Job’, but Isidore, his contemporary, had much broader and more lasting influence.

Isidore of Seville lived from 560-636 AD.  His huge work,  Etymologiae, remained the standard reference  for information about  .. well, almost everything…  from the time of its composition to as late as the sixteenth century.  Today there survive more than a thousand manuscripts in which the work is found copied in part, entire, or as a compilation of excerpts. According to one anonymous modern author, the full text of the Etymologies was printed in ten separate editions between 1470 and 1530, that is, at the height of the Renaissance. 

We can safely suppose, therefore, that what Isidore says about the stars would have been known to the monks of Burgos, as to the scribes in northern France who made Brit.Lib. MS Add. 17808 in that same century.  Of this second manuscript, more below.   Here are some of Isidore’s dicta: 

Astronomy distinguished from astrology.

The difference between astronomy and astrology

There is some difference between astronomy and astrology. Astronomy concerns itself with the turning of the heavens, the rising, setting, and motion of the stars, and where the constellations get their names. But astrology is partly natural, and partly superstitious.

It is natural as long as it investigates the courses of the sun and the moon, or the specific positions of the stars according to the seasons; but it is a superstitious belief that the astrologers (mathematicus) follow when they practice augury by the stars, or when they associate the twelve signs of the zodiac with specific parts of the soul or body, or when they attempt to predict the nativities and characters of people by the motion of the stars.

Bk2 xxvii.

Despite that last sentence, his Etymologiae was still copied, and then published to a willing public, long after the ‘zodiac body’ became a commonplace in medical texts.

Proper purpose for stars – including those of the zodiac.

Constellations (sidus) are so named because sailors ‘take bearings on’ (considerare) them when they set their course, lest they be led elsewhere by deceptive waves and winds. And for that reason some stars are called signs (signum), because sailors observe them in steering their rowing, taking note of their keenness and brightness, qualities by which the future state of the sky is shown. 
But everyone pays attention to them for predicting the qualities of the air in the summer, winter, and spring seasons, for by their rising or setting in specific places they indicate the condition of the weather.

Bk.III, lxx.4

That is why so many medieval breviaries and calendars can include emblems for the 12 constellations. It is not evidence for, nor indication of, astrological reference, but that has proven difficult for some Voynicheros to absorb, since today many regard any zodiac as if astrological by definition, and regard the constellation emblems as no more than ‘birth signs’.

Mathematics and improperly ‘calculating’ the stars.

For Isidore – and thus for most medieval Europeans – the evil uses were those employed by a calculating mind.

 But whatever the type of superstition with which they have been named by men, the stars are nevertheless things that God created at the beginning of the world, and he set them in order that they might define the seasons by their particular motions. Therefore, observations of the stars, or horoscopes, or other superstitions that attach themselves to the study of the stars, that is, for the sake of knowing the fates – these are undoubtedly contrary to our faith…

But some people, enticed by the beauty and clarity of the constellations, have rushed headlong into error with respect to the stars, their minds blinded, so that they attempt to be able to foretell the results of things by means of harmful computations, which is called ‘astrology’ (mathesis) .

Bk.III.lxxi.23

and again:

24. These are commonly called astrologers (mathematicus); the Romans call this kind of superstition ‘constellations’ (constellatio), that is, observation of the stars – how they relate to each other when each person is born.

The first interpreters of the stars were called Magi (magus), as we read of those who made known the birth of Christ in the Gospels; afterwards they only had the name mathematicus.

Knowledge of this skill was permitted only up until the time of the Gospel, so that once Christ was born no one thereafter would interpret the birth of anyone from the heavens. 

Bk. VIII.ix.24-25

A scholastic miscellany made in France between 1309 and 1316, Brit.Lib.Burney MS 275 includes matter from Boethius, Aristotle, Euclid, Adelard of Bath, and Ptolemy and its tables (e.g. on f. 398) are written in Hindu-Arabic numerals.

Nonetheless, the margin of f.336r includes a visual ‘warning off’ about these numerals as founded on matter ‘of the devil’.

In depictions of the liberal arts, the teacher is normally an allegorical figure, but here she is made alive, a woman looking upon these innocent students and with wide, bold eyes (i.e. in an ‘unwomanly-wicked’ way). Even so late in European history, there was plainly some residual suspicion of Arabic numerals, introduced to Europe as they had been in association with the Arabs’ ‘mathesis’.

Understanding these ideas, it is easier to appreciate what implications might be carried by two large green stars set in the margin of a page in Brit Lib. MS Add 17808, whose incipit (first phrase) reads:

 ‘Mathematica Alhandrei – summi astrologi..’

Mathesis and astrology and from a foreign author and he not Christian.

Very worrying stuff for an eleventh-century monastic scribe, concerned for his immortal soul, yet bound by a vow of obedience even as Isidore’s words came to mind, “harmful computations, which is called ‘astrology’ (mathesis)”.. “undoubtedly contrary to our faith”.

Green stars.

green stars faith hours BritLib Add MS 1708 header
green stars alone from Brit Lib Add 17808
detail folio 108r

These marks are so unusual that the cataloguer describes them as “stars(?)”.

They are not formed like the asterisks which, in Latin manuscripts, mean that a passage ‘a‘ links to passage ‘b‘. Nor are these like Quire 20’s flower-stars.

The Latins’ textual asterisk was formed as an ‘X’ with a dot in each quarter – as Isidore says:

In the eleventh-century manuscript (Brit.Lib. Add. MS 17808) the first of those two ‘green stars’ is set beside an area left blank.

We would usually suppose that the space had been left for the pictor to add some image, and since the other ‘starred’ paragraph names the 12 constellations of the zodiac, we might expect that image to be a depiction of the 12 constellations or their emblems, and further suppose that the pictor just never got around to it. This is not the only example of such blank spaces in medieval manuscripts.

However, those easy assumptions are not so easy in this case, because the character of this text is unorthodox for that time and someone – presumably the same overseer who put those green stars in the margin – has instructed the scribe to go back and insert into what had been a paragraph space, immediately after the names of the twelve constellations, the text of biblical passage and to write it all in capital letters.

The passage is from the book of Genesis. Its quotation, in this context, conveys a caution – even a warning – to scribes and subsequent readers. Given the nature of the text and Isidore’s proscriptions, the addition of the sentence: ‘God disposed them as signs for the hours of the night’ reminds a reader that the purpose in copying this material is to assist with correct observations of the night offices and the calendar, so as to remain in step with the divinely ordered heavens.

For that, no anthropomorphic images of ‘pagan’ gods were necessary; the constellations (constellatio) need not be drawn. The hours’ stars could be pointed out in the sky and calculation limited to that needed for computus, to establish the date of easter.

An entire side of folio 100 is also left blank.

That manuscript is very well known today and despite any effort to keep its use on the right side of a theological line, the Liber Alchandi came to be associated chiefly with ancient mysteries and near-magic. Not everyone felt so averse to picturing the pagan constellations, of course.

Thorndike refers to this manuscript when noting that Peter  of Abano, in his  Lucidator astronomiae (1310) “mentions Alchandrus…

“..as a successor of Hermes Trismegistus in the science of astronomy but as flourishing before the time of Nebuchadnezzar.”

Thorndike comments

Al chandrus was  scarcely as ancient as that, but the treatise ascribed to him also exists in Latin in a manuscript of the tenth century.. it is full of Arabic and Hebrew words, and professes to cite the opinions of Egyptians, Ishmaelites, and Chaldeans in general as well as those of Ascalu the Ishmaelite and Arfarfan or Argafalan or Argafalaus  the Chaldean in particular.”

In sum: Editorial ‘green pencil’?

All of which, together, leads me to think that the ‘green stars’ in that French manuscript are more like marks from an editor’s blue pencil – Someone had to instruct the scribe to add the biblical passage, and perhaps instructed the pictor that his work would not be needed for some parts of the copying.

Might the green stars on folio 67v of Beinecke MS 408 be another case of an overseer’s corrections, rather than indication of the three stars’ having some special significance?

I’ll take a closer look at that in the next post and touch on the fascinating topic of colour and its associations in pre-Renaissance period.

More ideas from Isidore about the stars.

Isidore was a man of his own time, not ours and also believed the following:

lxi. The light of stars (De lumine stellarum). Stars are said not to possess their own light, but to be illuminated by the sun, as the moon is.


lxii. The location of the stars (De stellarum situ) Stars are unmoving and, being fixed, are carried with the heavens in perpetual motion. They do not set during the day, but they are obscured by the brightness of the sun.


lxiii. The course of the stars (De stellarum cursu) Stars are either carried or move. The ones that are fixed in the sky and turn with the sky are carried. But some [like] planets, that is, ‘wanderers,’ move. However, they carry out their roaming courses within a defined boundary.

Addendum to Part A. extracted from a much longer post first published in Findings (May 15th., 2010). I add it for those interested in the traditions which came to inform western medieval ideas and art, but not to assert or imply that the makers of our fifteenth-century manuscript were so deeply informed.

The ‘bearded sun’ wasn’t the first intimation that the manuscript’s pictorial text’s themes and forms  do not originate in medieval European culture, but it was an important detail, and the idea of a bearded sun was not unfamiliar, but chimes rather well with what Georg Baresh believed about how the material for the manuscript had been gathered.

Carthage between the horns and wine-dark sea as city of god

 I began explaining the diagram and its implications quite early, sharinngthat information, initially, in a post of April of 2010,  and adding more in subsequent posts to clarify e.g. a link to Carthage, to the ‘grape-pressing’ motif seen in early Latin representations of (St.) Barbara and explaining that character’s ancient origin in North Africa, where the ‘grape-crushing’ is partly an allusion to suffering, but also to the “wine-dark sea” as Homer knew. 
Barbara tanit Phoenician stele
 
As late as the fifteenth century, Ibn Majid confirmed that the mariner-pirates of the north African shore had the same skills and star-lore as his own, and that the two were therefore brethren by that an inheritance which predates the 7thC Ad.  Here’s a little of what I posted on  May 15th., 2010, including the two previous illustrations above and those below. (Notice also the wreathed face at the apex of that Punic tombstone).
In Vezelay, the carver knew, pretty well, what he was about. He knew this figure, the spirit of the wine, was ‘la femme de le barbe’ – or ‘la femme a barbe’ though today the commentary is likely to argue the figure a saintly ‘master’ rather than celestial mistress of the wine. The carver has even known to place the figure’s foot on the highest leaf of the vine
In the classical period, North Africa had a very considerable industry in wine and grapes. It was remembered by the maker of the Atlas Catala, Abraham Creques, who wrote that after the Flood, Noah came to rest in North Africa, and first planted the vine there on the shores between the sea and Monte Clara.
Bedu woman with traditional tattoos. The Bedus traditional star lore relates to wayfinding and maintains proverbs of astonishing antiquity, remembering when Canopus (the ‘lucifer’) fell from a higher place and when the northern pole star was one in Draco, which astronomers inform us was the case from 3942 BC, until 1793 BC when alpha Draconis held that place
The Berber and Bedu tribes of North Africa had been largely instrumental in finding the way for the Muslim armies to successfully enter Spain. At that time they spoke of themselves as the “men of the ribat” – the military tower. The same term is used in that region for the sequence of lunar asterisms which the Arabs call the moon’s resting-places, or manzil al kamar. That sequence described as of 27 or of 28 asterisms is a convenient way to make finer divisions of the year’s circle, and thus to reckon such things as direction time and tide.
The name ‘Barbara’ sounds innocuous enough, but it seems it anciently named the star-[worshipping] people who considered stars to be small, distant lights: “grandchildren of the sun” [bar-bar-ra].
Hourani reports of the eastern tribe of the Azd, formerly of Arabia, that when were these Arab mariners [of the eastern sea] found themselves deep in a trough between mountainous waves, a chant was started which ran: “Barbara and Jafuna: look to your waves. Jafuna and Barbara: your waves are wild [lit: mad]. Jaffna is still the name of a Tamil area in Sri Lanka; the Barbara belonged to both the eastern and western horns of Africa. The greeks employed a similar term to mean ‘barbarians’ as persons who did not speak Greek.

David Pingree

In 1982, the Journal of the Warburg and Courtauld Institutes (Vol. 45) published the paper:

David Pingree,  ‘An Illustrated Greek Astronomical Manuscript. Commentary of Theon of Alexandria on the Handy Tables and Scholia and Other Writings of Ptolemy Concerning Them’.  ( pp. 185-192).

I begin by mentioning it for several reasons.

The late Prof. Pingree is one of the “two Davids” whose works are among those indispensable for study of what some pre-modern peoples knew about stars and – most pertinent to our chief study – how they thought about and imagined the heavens.

The ‘other David’ of the two is David A. King, whose works include the Ciphers of the Monks, in which King drew attention to the same Picard instrument whose orthography for month-names is – as I think Pelling first observed – closely similar to that of the Voynich month-names’.

Since the matter of  ‘Occitan month-names’ is among those affected by metaphorical ‘palimpsest-ing’,  I add more detail.

Writing in 2004, Shaun Palmer credits Stolfi with the proposal and (quite properly) notes that Pelling had come earlier than himself and independently to hold a similar view.  Pelling’s book (2006) then treated and illustrated the issue in  detail (pp. 21-23).  Those three  references should give you a clear idea of the evidence and substance behind this now-widely-accepted view.Searching for ‘Occitan’ today at voynich.nu I found the references given on this point to be an anonymous blogpost of 2012  and a note of thanks to Don Hoffman for providing Zandbergen with bibliographic details of King’s book. Following the principle that  “no acknowledgement asserts no debt”, readers might assume all  unprovenanced matter on that page (which is copyrighted  to  the owner as is every blogpost)  must be a result of the owner’s own research, crediting Zandbergen accordingly.

That paper by Pingree is chiefly concerned with the manuscript Ambrosianus H. 57. sup. (= 437). The ‘tables’ in question are known as  ‘Ptolemy’s Handy Tables’ but were compiled from Ptolemy’s data a century later, by Theon of Alexandria.  Researchers working on the Voynich manuscript might like to consider, in addition, matters associated with Ptolemy’s Geography, as balance for a tendency to associate Ptolemy solely with astrology, or even solely with astronomy. See e.g.

  • Dmitry Shcheglov, ‘Hipparchus’ Table of Climata and Ptolemy’s Geography’, (available through academia.edu)

 

Question 1: Is there Astrological matter in the month folios?

Caution Newcomers should be aware  that nothing in the manuscript has yet been proven related to any branch of occult or pseudo-scientific practice including that of astrology, though  speculation has been so common –  thanks initially to Wilfrid Voynich and his inflation of the ‘Rudolf rumour’ – that many imagine it has been proven beyond doubt.  Yet the stars are part of the natural world and natural, too, may be their observation and depiction.  To represent the theological position of the earlier medieval west, we may refer again to  Augustine:

Amiens Cathedral exterior: Virgo = Threshing               see   labours of the months.

Who can fail to perceive how great is the difference between useful observations of the heavenly bodies in connection with the weather, such as farmers or sailors make … and the vain hallucinations of men who observe the heavens not to know the weather. or their course … but merely to pry into the future ….

from Augustine’s Letters  55 15

  • Anne Lawrence-Mathers, Medieval Meteorology: Forecasting the Weather from Aristotle to the Almanac (2019)
why is the astrological  idea a problem?

Objection 1.  The idea’s introduction depended entirely on ideas about John Dee’s connection to the manuscript, in combination with consideration (only) of the month-names and central emblems from the month-folios.  The latter were taken to depict the ‘signs’ forming a tropical zodiac, rather than taken literally as a depiction of the physically-visible constellations which appear in sequence through the seasons of the year.  The conflation of constellation with astrological ‘sign’ is endemic in Voynich discussions, even today.  

Even if the emblems did constitute a representation of the zodiac ’12’ there is no necessary connection between their depiction and that aspect of mathematics which defined astrology in the medieval world.  In other words, there is no necessary connection between a depiction of the ecliptic constellations and tropical- or sidereal astrology.  

That the opposite idea should be so prevalent in Voynich writings today is due to the fact that most modern readers, living in an industrialised society and urban environment, don’t need to know the stars as people did in earlier times.   Today, we use clocks, watches and phones to know the time; we learn from the weather man what sort of weather we’ll have today; we rely on automatic or printed calendars to tell us where we are in the cycle of months and seasons.   Reflection from city lights, and nights spent indoors (or outdoors) under artificial lights means  many see none but a few of the brightest stars in the night sky.   And all this, together, means that the word ‘zodiac’ instantly evokes the motifs of ‘birth-signs’ and daily horoscopes for us today, and thus seems the ‘most obvious’ interpretation for any comparable series, especially if stars are depicted. 

 Thus, the constant error has been an imposition on a manuscript  six hundred years old, the hierarchy of ideas proper to twentieth- century urbanites.

Things were different six centuries ago.

Objection 2.  No  zodiac sequence contains (as the month-emblems do) two goats, or two sheep,  or a sheep and goat adjacent to one another.

This issue and others raised by the month-emblems are rarely even noticed today by Voynich writers. and of the few who do notice, fewer speak, and of the very few who do mention a problem, the majority do not address that problem so much as seek a way to turn back into the fold any who show signs of doubting that “its-a-zodiac-and-zodiac-means-astrology” proposition chain.    In private conversation a Voynichero once said that he didn’t include both pros and cons in his own writings  because “if your mind is too open, your brains fall out” – which sounds to me like some conservative slogan gone wrong. 🙂

Objection 3. Even if we grant that,  in adding the month-names later, the person who did that truly  believed  the emblems represented constellations from the zodiac, more cannot be deduced from it than  he had  regarded the series as a series of months and their stars.  It is no support for an idea that  “months+stars means astrology”.  

Objection 4. is that the the Voynich series names only  ten months, and the months omitted (January and February) are – perhaps coincidentally or perhaps not –  the months when the fields were dormant, and when  ships of the Mediterranean stayed in harbour. The ‘sailing year’ ran from March until (nominally) November but the historical records show that in fact ships of the harbours where the most competent seamen were based might continue  sailing coast wise even as late as December.

Other points:

  • An argument that the remnants of two cut pages following  the month-diagrams  had once contained two more diagrams of that sort is – like theorised astrological purpose – only speculation at present. 
  • As I’ve explained elsewhere, correlations of month-name, month-marking constellation, and associated ‘labour’ were not uniform  even within Latin Europe., and the correlations made in the month-diagrams between emblem and month-name are not those of the northern latitudes (England, Germany and northern France).
  •   When responding to a Voyichero’s query,  Prof. Ewa Sniezynska-Stolot of the Jagiellonian University in Cracow – whose area is given as the history of European art, especially its traditions of astrological imagery-  also mentioned calendars in connection with the month-diagrams’ central emblems.  Here the difficulty is that her opinion was a short note written in response to a Voynichero’s query and it appears she was given no indication there was any reason to doubt that the content in this manuscript might have any but a medieval Latin European origin.  The answer of an expert is typically provided within the framework of the question posed.  Not knowing that explains why William Friedman got so little from Panofsky, where Anne Nill had received so much more  – and we’re not talking word-count here.
  • Nor do we know what Sniezynska-Stolot was shown of the manuscript at the time (2000), or whether in colour or copy-flo.   As translated by  Rafel Prinke and  reported in Reeds’ mailing list, her note has a distinctly off-hand tone.

By  13 Jan 2001 her note’s content was already reported to Reeds’ mailing list and members were discussing it in  connection with specific problems of the kind no longer acknowledged as existing by the most conservative faction and whose discussion is thereby discouraged, with ‘blanking’ from the record of any non-conservative who might do so. 

Still – let’s move on to one possible hint of the astrological… and trust our brains won’t fall out. 🙂

Astrological versus (purely) Astronomical

Exaltation and Depression?

Consider the following pair  from the first of the ‘April’ diagrams (folio 70v-ii), keeping in mind that the fifteenth-century draughtsman could draw ‘nicely’  but for reasons as yet unclear, didn’t wish to.  What message are we to take from their presentation? What aspects are we supposed to  read as meaningful? What about their postures, for example?

 

Did the original maker  intend the male  figure is to be read as ‘elevated’/’exalted’ and the female as ‘dejected’ or dismayed?   Or are our  subjective reactions focusing on details he would have dismissed as irrelevant?

If he meant attention paid to their posture, we must realise that such terms as ‘elevation’, ‘exaltation {Gk. ὕψωμα]  and ‘dejection/depression’ [Gk. ταπείνωμα] were used technically of the planets in Byzantine astrology, while  “seldom, if ever, found in the West” -as Pingree observes, though he finds that their illustration  in  Ambrosianus H. 57. sup is drawn ‘in western style’.

Indeed, the draughtsman’s style may be western, but it has  little in common with that of the person who drew the unclothed figures in the Voynich month-folios, except perhaps a common implication (also found in certain Islamic texts) that when figures from polytheistic religions are presented, the images should express moral censure. (see further, below) I say ‘perhaps’ because we have no proof thus far that the Voynich figures were intended as deities or anything of the sort. Neither have I seen any argument which proves that  the Voynich manuscript depicts any of the five planets, let alone all of them.

*The planets proper, the ‘wandering stars’, included only Mercury, Venus, Mars, Jupiter, and Saturn in medieval times.

re planets…2001

In 2001, a member of the first (Reeds’) mailing list responded to Robert Firth’s comment on the fact that the ‘celestial’ folios hadn’t served as key to the written text as many hoped they might,  by saying  that “we” ‘ ..have quite a number of good (even if not dead certain) [identifications]:- the Pleiades and Aldebaran; – the seven planets; – two sets of twelve labels in 12-segmented circles; – one (or two?) set of 28 segments, “obviously” indicating the mansions of the moon. (12 Jan 2001).  All members of that list, at the time, would have known which of them had contributed each item, with what evidence and what argument (if any) but as yet I don’t know. If you can enlighten me on the point, please do. I’ve seen nothing one could call a cogent argument for it between 2008 and today.

detail) Milan, Ambrosianus H.57.sup. f.112v. Venus – on which see Pingree (1982) p.32

The unclothed pagan deities for each planet are depicted with a certain censure in the Ambrosianus manuscript  –  e.g. Venus (right) is depicted as as a debauchee – given the face of a young and pretty woman but a body heavy, old and exhausted from bearing children by various fathers. I see little obvious similarity between the draughtman’s style and that in the Voynich month-folios.  Expressions of moral censure in depiction of figures from polytheistic religions are  also seen in some Islamic works, notably in the  ‘Book of Marvels’ ‘Kitab al Bulhan’ (MS. Bodl. Or. 133) a seventeenth-century work (or copy) where Voynich-like “glyphs” were also inscribed.

That-last point was initially brought to notice by – I believe  – by Nick Pelling in his review (2008) of Okasha El Daly’s book. A detail (‘Crab’) from the same Bodley ms was later considered by one Voynich blogger whose blog I cannot find online today. In two posts of 2013 the present writer commented on several of  images from that manuscript, together with  other examples of ‘Voynich-like’ glyphs.

An image posted to pininterest by Marco Ponzi associates a detail from the Bodleian ms with one on folio 67v 2. His commentary may appear elsewhere but I’m not willing to join that site to find out.  (Again, if anyone already has more detail, I’d be happy to include it in the comments section below this post.)

On the Greek astrological terms and their significance see e.g.

  • Roger Beck, (2017) A Brief History of Ancient Astrology  pp. 242ff.
  • Chris Brennan, Hellenistic Astrology: The Study of Fate and Fortune.
  • James Evans. Time and Cosmos in Greco-Roman Antiquity (p.135). Evans’ equating ‘Chaldean’ with ‘Babylonian’ is over-confident.
  • Tamysn Barton,  Ancient Astrology (2002).

Neither  Aratus/Cicero’s Aratea, nor Manilius’ Astronomica  (written  c.30–40 AD) makes use of the planets, a point to be kept in mind given the date for Vat.gr. 1291 and possible  pre-Christian (but anti-Greek? anti-polytheist?) origin for its ‘women of an hour’ (see previous post).

Manilius in the west

Goold believed that before his election to Pope, Gerbert d’Aurillac had found in Bobbio a copy of Manilius’ Astronomica bound (as Gerbert said) with a copy of Boethius’ text on mathematics. Other scholars have doubted this, attributing the west’s knowledge of that text (as we have it) to Poggio Bracciolini’s practice of  commandeer manuscripts from monastic libraries by his position as papal secretary.  The ‘discoveries’ were then copied (at a price) for members of the Italian literati, who appreciated Poggio’s ‘little arm’. His own view is recorded in one colophon, which translated reads “This oration, formerly lost owing to the fault of the times, Poggio restored to the Latin-speaking world and brought it back to Italy, having found it hidden [sic] in Gaul, in the woods of Langres.” If he had acquired it from Bèze abbey, that copy is unlikely to have been older than the 11th-12thC.

Again with the older period in mind, and possible bridges between  pre-Christian astronomical works and the early fifteenth century when the Voynich manuscript was made, I’ll add here part of the description of Niceforous’ visit to Cyprus in the fourteenth century.  There was still a Lusignan ruler in the island, one who with his chief scholar George Lapithes asked the noble visitor from Constantinople to summarise for them as many astronomical texts as they could gather. They brought him copies of Ptolemy’s works, including the  Tetrabiblos, called Ἀποτελεσματικά ετράβιβλος in the Greek – but also,  according to  Niceforous (I quote from another paper by Pingree):

“all the books that still existed composed about such matters, by Ptolemy’s predecessors and by more recent authors as well as those that had been written in antiquity and by the  Chaldaeans and the Persians”. 

  • George Lapithes and David Pingree, The Byzantine Version of the “Toledan Tables”: The Work of George Lapithes?’, Dumbarton Oaks Papers, Vol. 30 (1976), pp. 85+87-132.

Pingree offers evidence and argument for a/the Greek translation of the Toledan Tables’  in Cyprus during the first half of the fourteenth century, to which same period, as it happens, I assign their ‘return to the Mediterranean’ phase for  the majority of parts in the Voynich manuscript.

Ambrosiana H.57. sup. – evolution 2ndC AD – c.1458..

Claudius Ptolemy lived in the 2ndC AD.  Theon of Alexandria in the 3rdC AD.   So then, discussing the content in the Amrbosiana manuscript, Pingree tells us:

We may conclude, then, that the original [i.e. the Ambrosiana] manuscript was copied in 1358, and that a series of owners for the next century added to it, rearranged it, and annotated it. It is likely that the manuscript was copied in Byzantium, and remained there while these changes and additions were being made to it. There is no absolute proof for this supposition in the manuscript itself, but it is known that the texts in Ambrosianus H. 57. sup. were copied in part from Laurentianus 28, 7;3 and that manuscript can be shown to be Constantinopolitan. (Pingree, op.cit. p.186)

and

There is no doubt, on the evidence of the script, that the codex could have been written in Constantinople in 1357-58. It is in the style associated with the Hodegoi scriptorium over a period of about half a century.  Western connexions of this scriptorium are not apparent. If they existed they would be more likely at this time to have been with Venice than with Southern Italy.   (ibid. p.192)

.. yet when it comes to those miniatures …(emphasis is mine)

The consensus of opinion is that the style of the miniatures is basically Western, though with an admixture of Byzantine elements. Islamic tradition lies behind the curious iconography, in which the planets are shown with their day- and night-houses, exaltations and dejections: this is seldom, if ever, found in the West. No immediate model has been located in an admittedly cursory search. An artist active in Southern Italy or Sicily may be indicated by the mixture of Italian and French styles. It is not impossible that an artist of, say, the Neapolitan school was working in Constantinople in the mid-fourteenth century – a time when others (Barlaam of Seminara, for example) travelled freely between that city and Italy. No artist answering to this description can, however, be securely documented in Constantinople at this time. Nor can it be assumed that the manuscript was decorated in the same place as it was written: the illustrations may be later additions. Indeed, they look very much as if they are.    (ibid. p.192)

 

For those who managed to come so far   –  here’s the sweet….

B. Astronomical?

Returning to the pair on folio 70v-ii, a closer look at the female figure…Short-ish hair, large head, figure’s right side drawn with a swelling line, indicating a breast. But where the figure’s left breast would be, there’s only what appears to be a piece of skin, marked with lines evoking sutures or something of that kind. Obviously not a skin-graft  (skin-grafting, history of)

We have a word for females who display just one breast. It’s from the Greek: a- (ἀ-) which means lacking and mazos (μαζός), which means breast   ..so, …”without breast”= Amazon.

Classical Greek and Roman imagery doesn’t depict Amazons  lacking a breast. They show a figure who is usually short-haired,  sometimes in armour which can include a breast-cover, or with only one breast covered by clothing and/or armour.

Interestingly, on fol. 70v-ii, the breastplate has been understood by the draughtsman to be of the high-collared type. The two images (at right) are shown simply to demonstrate that high-collared breastplates,  for females, are not entirely unattested.  An amazonian caryatid in Dresden wears armour very similar in deign to the Keralan type. That caryatid is described (by a seller of prints) as  ‘an ancient wall sculpture’. I can only say that their definition of ‘ancient’ is unusual.

The Keralan tradition marks by such means one of the eight chief patron- ‘mother’ goddesses, known to be warrior-women when necessary.

To this day women archers may don a breast cover in addition to the cover always provided for the forearm by the long, skin-tight sleeve and/or by a wrist-guard which might be better called a forearm-guard (but isn’t).  These were traditionally made of thick leather; The present day Olympian (below) wears ones of modern materials.

When you consider that women in pre-Renaissance Europe didn’t normally ever handle a bow, and that  the two drawings in the lower register were made  two thousand years apart from each other, the conceptual image informing the physical image per se has evidently survived remarkably well. The fifteenth-century draughtsman understood his exemplar.

 

So now – which star(s) if any might have been identified as  ‘Amazon’ by any tradition of star-lore, at any time between the 5thC BC and 15thC AD? Here are two possibilities from the Greco-Latin-Arab traditions with which I think readers will be most familiar.

 

  1. alpha [α] Virginis (Lat.Spica) ?

According to the 15thC Yemeni, Ibn Majid, the star α Virginis serves as the manzil (lunar station/mansion) and in that context is known as Simak al A’zal, ‘warrior without a spear’ (Tibbett’s translation p.100). And the figure from the first April diagram certainly has none.  However, women of the Arab tribes in Arabia, and more particularly of the Yemen, appear from the early accounts to have been treated more on par with men and in the pre-Islamic period to have been decidedly martial. By comparing with both older and early medieval works, it appears that until the seventh century AD, α Virginis may  have been often envisaged as a female warrior, one who roared or howled in the attack.   As Virgo, she is still armed in an image within the 9thC Byzantine manuscript Vat.gr.1291.

9thC Greek  (prob. from a late classical source)

A star-ceiling made in Egypt under the patronage of the Roman emperor Tiberius in 50BC, shows Virgo holding a ‘spike’ staff of some kind. The image shown here (below, right) is  as illustrated by Wallace Budge.

1stC BC. image in late-Hellenistic Dendera. If the spike is papyrus, the use of palm and scroll as alternative is understandable.

While Virgo’s spike-star  was generally envisaged as a stalk or sheaf of wheat for most of the Latin period, the alternative tradition was not forgotten, and the late image seen below shows how it was preserved – as a martyr-like palm branch held delicately by a more passive and ladylike virgin angel.

So if this is the intention behind the ‘Amazon’ on folio 70v-ii, her being without a weapon may be due to the same cultural attitudes (not necessarily Arab) which sees  the ‘ladies of an hour’ drawn with arms deprived of strength in Vat.gr.1291 folio 9r- as we also see   in the month-folios of the Vms.

Libra

In both instances, the informing ideas appear to me  indicative of deep-seated belief that the stars had effective power to harm and I doubt such fear derives from the classical Greeks or from the Orthodox Christians of ninth-century Constantinople. That Vat.gr.1291  has drawn on ideologically opposed traditions is evident if one compares the charming figure for Virgo in the ‘helios’ diagram (folio 9r) with the frankly unnerving and skeltal ‘ghost’ which is one of the few figures un-erased from the same manuscript’s planispheric ‘night sky’. (right)

So let’s return to the charming Virgo.  Unlike her counterpart on folio 23r of that manuscript, hers is not  the stocky body we associate with Europe’s late Roman art. She is envisaged as a slender and elegant messenger, whose ‘spike’  now appears more like rolled scroll. (angelos means ‘messenger’.)

This may be a good moment to remind readers that Alain Touwaide said the Voynich manuscript’s appearance suggested to him the sort of Byzantine hospital workers’ notebooks called iatrosophia, though it wasn’t one.

Touwaide has studied such manuals within his wider area of specialisation, and among his publications  is

  • Alain Touwaide, ‘Byzantine Hospital Manuals (Iatrosophia) as a Source for the Study of Therapeutics’, in Barbara S. Bowers (ed.), The Medieval Hospital and Medical Practice  pp.147-173 of Vol. 3 of AVISTA Studies in the History of Medieval Technology, Science and Art, (2007).

I agree that in the  Vms, we have a compilation of matter brought together for an entirely practical purpose, and find it possible the ‘bringing together’ may have occurred in comparable circumstances, and even within the Byzantine sphere, but having already treated in detail a large proportion of the Vms’ imagery,  I am glad that I am not in the unenviable position of having to differ from Professor Touwaide on the ‘practical handbook’ issue, or the ‘compilation’ issue, though I should have been obliged, unhappily, to do so had he said the whole was a work of medicine, or even of astrological medicine.

  • at the moment I can’t refer you to the printed version of Touwaide’s Voynich talk (or, rather first Voynich talk) at Mondragone.  The book is unobtainable, and Stephen Bax’ site where it had been shortly reviewed is presently infected by some virus.  Maybe later.

2. gamma [γ] Orionis.

Hinkley Allen informs us that in  “the Alfonsine tables” (no version or copy is specified) the star γ Orionis has a previously-unattested name, as  Bellatrix – a term from Latin and which means again, a female warrior.

Note – Ptolemy’s Tables, Alfonsine or Toledan Tables in Voynich studies

I was surprised to find no mention of any of these tables in Voynich writings or chats until speculations about occult topics had taken been current for about ninety years.

One would have thought an examination of standard sources for astronomical knowledge would be tested first before resort was had to speculation, but things went the other way.  Perhaps, yet again, we must attribute this oddness in the study first to Wilfrid Voynich’s tale, and a feeling among some that support for the ‘Rudolf’ idea had to marshalled.   However that may be, even today (Nov.2019), I find no mention of the Toledan tables at Nick Pelling’s site, or at voynich.nu.  I believe there was some talk of them in comments to Stephen Bax’ site, but at present it is under ‘virus interdiction’. I hope to check it and properly credit anyone who posted there if/when the site and its comments return.

Otherwise, I have found nothing about the Alfonsine or Tioledan tables (do let me know if you know better) until 2002 (ninety years after Voynich acquired the manuscript), when Luis Vélez’ says in  Reeds’ mailing list (Tue, 16 Jul 2002):

Thus, students of medicine at Bologna… learnt astrology [sic.] for four years, including grounding in Euclid’s geometry and Ptolemy’s Almagest. In addition, they learnt how to use instruments such as the astrolabe and the quadrant, and were taught how to use the Alfonsine Tables along with their canons. ..

 

Hinkley-Allen suggests ‘Bellatix’  was gained by mis-translation of an Arabic term, ‘roaring lion’.  I should have been inclined to dismiss this altogether, as mere transposition of some term for a star in Virgo – except that it survives experiment extremely well.  Experiment involves cultural and specific context, in addition to the image’s individual characteristics and drawing-style.

As you see, where the chap looks quite upbeat, the female looks decidedly “down”, doesn’t she?

Those interested in the written part of the Voynich manuscript might care to research uses for the opposition between elevation/exultation and subjection/ being downcast as applied by older works to matters other than planetary dispositions.

And with these two feasible identifications, mentioned  I’ll leave the astronomical and astrological possibilities for you to think about, except a last note that in another place, according to Tibbett’s note, al ibn Majid identifies Bellatrix with Orion’s hand [lit. Yad al Jauza’, usually Betelgeuse],  and it is in connection with this passage that Majid relates a condensed ‘cipher’ mnemonic for some fairly technical and mathematical matter.

Should it be of interest to any reader, description of that ‘cipher-mnemonic’ runs from the last paragraph on p.87 to the end of the first paragraph on f.88 in Tibbett’s English translation..

Postscript: From the research into historical and cultural context – I think one topic should have been mentioned, viz. the Indian tradition.  Thus, our Bellatrix (γ Orionis) is still recorded as ‘Yad al Jawzã’ al-Yusrã’ on astrolabes made in Lahore by a ‘dynasty’ of astrolabe makers in the sixteenth- and early seventeenth centuries.

  • see e.g. Mubashir ul-Haq Abbasi and Sreeramula Raeswars Sarma, ‘An Astrolabe by Muḥammad Muqīm of Lahore Dated 1047 AH (1637-38 CE)’, Islamic Studies, Vol. 53, No. 1/2 (Spring-Summer 2014), pp. 37-65

In the same context, the ‘serpentine’ extension behind Betelgeuse may allude to the ‘Ketu’ (headless body) of Rahu Ketu in Tamil and Hindu astronomy.  The sources differ considerably and I don’t want to give an impression that I place much importance on it.)

Also, we know that the Indian and Muslim traditions were both still present in Iberia during the fourteenth century, as Chabas and Goldstein (among others) have said:

quote stars Jews Spain astronomical tables 14thC Indian trad

Chorography..

I had meant to now talk about chorography, and identifications of stars with places – not by astrology but by an older system of observation and  a mythos of locality.. as well as by nominal superimposition of  celestial and terrestrial co-ordinates (made easier in medieval times if one had an astrolabe).

I would have begun from the classical sources’ identification of Amazon lands, by Herodotus and later authors, illustrated by a couple of maps, and then moved on to the technical correlations for star-and-place as well as the various astrological equations of peoples and regions …. coins, legends, Manilius, Dorothea of Sidon etc., remarks on Genoa’s colonies in the Black Sea (from c.1290s to the time the Plague came..) and so, eventually,  to Ptolemy’s co-ordinates.

But this post is already a trying length, almost 4,700 words, so I’ll leave all that material from my logs aside, except to say the Voynich ‘strings’ may bind place and star.

The star-place correspondence system has to be conceptual or temporary because the vernal equinox moves, as the first minute of right ascension doesn’t.  Then there are also the eastern navigator’s “fetterings” but …alas.. who’d ever read so much?

At least you have some sources for this last and  far from unimportant section.
