About a third of this post is for people working on Voynichese. Those paragraphs are marked with the partial-derivative symbol (right).
edited to correct mis-spelling – 25th Sept – somewhere along the line ‘Lippencott’ made its way into the spell-check’s ‘don’t check’ list. My apologies to the scholar.
Two lobsters: July
For newcomers – the ‘Calendar’ emblems so far:
Many Voynich writers focus on where the manuscript might have been made.
Our aim is more like the linguists’ and cryptographers’ – to understand what information the original speaker(s) intended to convey. Just as linguists don’t presume a new spoken language was invented for this manuscript, so we don’t presume the drawings are without precedents.
However, because so few among the manuscript’s drawings speak the visual language of medieval Latin Europe, our aim is (of course) also to identify their original source. In that, the relatively few which do ‘speak Latin’ (or something like it) are like the end of a thread which may guide us into, and then through, the maze of possibilities. Among those few are the small central emblems with which the ‘calendar’ diagrams are provided.
Diagrams referring to astronomical matters don’t exactly speak a universal language, but were – and are – less dependent on local customs for their understanding than is a written or a pictorial text.
Comparing information in some Voynich astronomical diagrams.
We don’t know what purpose the Voynich ‘calendar’ diagrams were meant to serve, but independent specialists have assured us they are not astrological charts.
At present we are asking whether the emblems offer astronomical information compatible with that found in two other astronomical diagrams (on folio 85r and on folio 67v-i).
These posts being exercises in analytical method, we are considering just two examples: the emblems inscribed ‘November’ and ‘July’.
* * * *
The ‘November’ emblem, as we found, is meant for a crocodile and is derived ultimately from one aspect of an originally-composite figure for the ‘croucher by the Scales’. Known as Ammit, its character was expressed by combining elements of the most savage bringers-down of prey: crocodile, hound/jackal, lion and hippopotamus, with all but the last reaching medieval western Europe as an expression of “scorpion nature” or as the Physiologus’ ‘crocodrill’.
Only one documented example of a ‘crocodile Scorpius’ has been seen, so far, from medieval Latin Europe before c.1350 AD. That was in BNF 7351, so that is where we take up the thread again – but not until committing to memory every detail of the image to be researched.

Observations:
Caution – the difference between someone naturally suited to a study of ancient and medieval art and artefacts, and someone whose talents lies elsewhere, often shows up at this first analytical stage. Be honest with yourself. If you feel impatient with process, over-confident, and want to rush to the ‘bottom line’ – this sort of work is not for you.
1. Remarkable absence of depth or perspective for a work often presumed created first in Latin Europe in the fifteenth-century. It is no product of the atelier. No attempt to provide background, whether of solid pigment, pattern, wash or a schematised landscape. Yet the quires are of vellum, albeit second-rate, and not paper which even by the fourteenth century would be used for rough work.
2.Each of the paired creatures is carefully distinguished – by its facing and by use of pigment. This is a characteristic of the ‘calendar’ diagrams overall; their many anthropoform figures are carefully differentiated by form, proportion, gestures, facing and/or facial expressions – which is a remarkable feat, if you consider their number, and the scale to which they were drawn. That even the month names which had to be inscribed twice are written differently, and evidently to avoid ‘replication’ argues in the original maker (and possibly in the fifteenth-century copyists) a cultural avoidance or ‘tabu’ which – though certainly attested at certain times and places – was never native to the Latins’ tradition.

3. Anatomy – (3.1) The creatures’ upper body (thorax) is made bulbous, not slender. Somewhat ant-like. Arcs are drawn on the thorax, left and right.
(3.2) No large front claw(s) as one would expect in a work produced from a fifteenth-century atelier in Europe.
(3.3) Abdomen ribbed to indicate segments.
(3.4) Divided ‘feet’ are given to eight slender legs extending sideways from the abdomen, Thicker-drawn versions of the same for the front legs to which claw(s) attach in a living specimen of prawn, lobster, crab etc.
(3.5)A tail is shown, fan-shaped and with four lobes.

(3.6) The head is given three points!
(3.7). Antennae emerge – one from each gap between those points – though in the upper figure the copyist may have been, initially, confused or affected by the scale at which he was working; one antenna seems, at first, part of the line or cord linking the two creatures.
In one sense this emblem is not ‘well-drawn’ but diverges from the literal less than a first glance might suggest. The creature is no fantasy beast. Following Lippincott and Gheuens, we’ll call it a ‘lobster’ though ‘crayfish’ or even ‘prawn’ might do.
Here’s the lobster’s anatomy…

… so what might be seen as errors come down to these:
(i) omitting any large front claw(s) ; (ii) confusing the positions of swimmerets and walking legs; (iii) giving all the walking legs split ends, where only the first four should have them; (iiii) giving the creature a head formed of three points (N.B. not one, two, or four, but three).
swimmeret: a swimming-foot; a pleopod; an abdominal limb or appendage usually adapted for swimming, and thus distinguished from the ambulatory or chelate thoracic limbs, fitted for walking or seizing.
If any series matching the series of Voynich ‘calendar’ diagrams, or its series of emblems has been found – or any match for this emblem – I’m unaware of it. To be a match for the ‘July’ emblem, the example would have to include two creatures of this form, similarly differentiated, and including all the characteristics just listed.
In the absence of any match, only comparisons can be offered and our first defining element will be the creatures’ “three-point” head.
Koen Gheuens has already followed the ‘legs-for-swimmerts’ confusion from the time of Michael Scot (d.1232) forwards, noting some instances across northern France and then in works produced by one artisan. That essay is linked below. Gheuens referred readers to Kristen Lippincott’s ‘Saxl Project’ pdfs and so do I. As far as possible, I’ll cite illustrations from that resource.

Lobster as Cancer – not so unusual.
What happened after c.1440 is of little interest to us. For this exercise, it is also necessary to count, as characteristics of the image, that these Voynich emblems are inscribed in a Romance dialect or language, and that this emblem is labelled ‘July’ – being in this unlike most Latin breviaries, books of hours and ‘Labours of the months’ series which assign the astronomical Cancer to June, and have the ‘sign’ straddle June and July.
On the brighter side, examples of Cancer’s being assigned, alone, to July, and Scorpius to November are not limited to the Voynich manuscript and the twelfth-century, Byzantine-influenced Otranto mosaic. Here (below) is the same assignment of emblem to month in a manuscript made about the same time as that mosaic but in south-eastern England. (Note here the single, loose loop for the Scorpion’s tail and that all the crab’s walking legs are given two ‘toes’, with the scorpions’ being given three).

Gheuens began with works composed by Michael Scot in Sicily – or rather with copies that were made later in Italy, but we are looking instead for the ideas and customs in art which influenced Scot’s thinking and that of the people who illustrated those Italian copies regarded as the four most important to survive.
*Glenn Michael Edwards, ‘The Liber Introductorius of Michael Scot’, thesis (PhD), University of Southern California, 1978
Michael Scot‘s lifetime (1175- c. 1232) overlaps with those of several other prominent Latin scholars whose names have been invoked at various times by various Voynich writers. The list includes the first ‘Gerard of Cremona‘ (1114 – 1187), or the second (13thC); the Flemish Franciscan friar, Thomas of Cantimpré (1201 -1272); the German Dominican friar, Albert of Lauingen (1200-1280), the English Franciscan friar, Roger Bacon (d.1292), and Robert Grosseteste (ca. 1168–1253), bishop of Lincoln and tutor of Oxford.
All save the Gerard(s) of Cremona spent some years pursuing higher studies in Paris, and it was from the region around Paris we have our only other documented ‘Crocodile-Scorpius’ in Latin Europe – so far – before c.1350. Scot and Albert of Lauingen also studied in Italy.
In a later post, I’ll speak about the activities of the papal court while located in Avignon (1309-1375 AD), but at present our focus is on matter that was current in Scot’s time,
When Michael Scot was born, about the second third decade of the twelfth century, texts and manuscripts were gained chiefly from copies made in monastic scriptoria, By the time of his death, such work was increasingly being done by students of the larger universities, particularly in France where some colleges associated with the University of Paris set aside a room for that purpose. Scot would also have seen the beginning of an increase in the commercial producers of manuscripts, in what were described as bottegas or ateliers. In Italy, there existed a system known as the ‘pecia’ system, whereby a student might copy from quires or sections of a manuscript which a stationer had broken into parts, the students paying for materials and for use of the wanted sections.
Outside the world of formal scholarship, ‘informal’ texts were being made, a majority on paper and the greater number of those we still have from Europe were made for and by its non-Latin communities, or communities united by their (non-academic) occupations.
Crab, prawn’ and lobster etc., in pre-Christian western art.

We’ve seen that images of the crocodile, in literal style, existed in Latin Europe in mosaics and other media as relics of the pre-Christian Roman era. There were also many naturalistic images of sea-creatures in such media, with North Africa preserving a large number of this type. The images shown at right, and below, are from Roman-Byzantine mosaics from north Africa. Those shown are described as Roman.

In some early astronomical illustrations from Latin Europe, the classical traditions in art remain evident, though did not long survive with the same clarity. The Crab in the Leiden Aratea is a case in point. The illustration’s classical lineage is unmistakeable and raises the possibility that we have it from an early copy of the first Latin translations from the Greek,

Compare that crab, for example, with the style in which the same creature is represented on an early (pre-Roman) coin made for Akragas in Sicily.

That coin was made a little before the birth of Eudoxus, the eastern Greek astronomer who spent time in Sicily and whose astronomical works were summarised and cast into poetry by Aratus.
I should also like to suggest that although the forms of drawing for constellations degenerated through the medieval centuries, that there may have persisted in some regions, and as a kind of folk-tradition, older ideas about the stars and constellations, and particularly associations between certain stars and constellations, and certain places. As the crocodile (for Scorpius) was universally associated with Egypt and the Nile, the Crab and ‘prawn’ spoke of Sicily and the Straits of Messina, respectively, as they had done even before the birth of Alexander.
The strait of Messina, between Sicily and the mainland, was renowned then as it is today for its dangers and for the chimerical images we call mirages or ‘Fata Morgana’.
The strait [of Messina] has strong tidal currents …. A natural whirlpool in the northern portion of the strait has been linked to the Greek legend of Scylla and Charybdis. In some circumstances, the mirage of Fata Morgana can be observed when looking at Sicily from Calabria.
After Rome conquered the island and thus claimed to rule the strait, we find a coin in which Latin permits, as canting, the Greek ‘Scylla’ to be Latin ‘scilla’ – a prawn. But the allusion is still to Sicily and that dangerous strait. Moon and tides are inextricably linked, so ‘to know your moon’ was to know your tides. This image is a Roman equivalent for ‘Britannia rules the Channel’.

What makes these antecedents of ‘lobster-prawn-Crab’ imagery so interesting is their age, and that they appear on these coins at much the same time that the astronomical texts were first composed on which Latin European scholars would rely from the time Rome fell until that of Michael Scot: Eudoxus to Aratus to the Aratus latinus and the abysmal ‘Astronomicon poeticon’ which is so unkindly attributed to Hyginus.
Another fascinating image from the same pre-Christian era was made for a Gallic tribe, the Averni. Aratus and Germanicus may have understood what these figures meant to the Averni, but modern numismatists simply call the form above the horse, ‘lobster-like’. It has been provided with antennae and there are three spikes or points to its head.

Ovid, we know, made one Latin translation of Aratus’ poem. Another is said to have been made by ‘Germanicus’ though just who he was is unclear. ‘Germanicus’ means ‘subduer of Germania’ but as Baldwin put it, “as a method of precise identification, the unadorned name of Germanicus [is] intolerably vague. Too many men bore the cognomen…”

TYPES of TEXT
From this point onwards, in addition to considering the emblem’s form, and the month assigned it, and its inscription in a Romance language or dialect, we’ll also take note of the textual setting in which a cited comparison occurs. So that those chiefly interested in the written text can skim the rest, I’ve marked those paragraphs with this symbol ∂
It is probably too much to hope that exemplar(s) used for this whole section in Beinecke MS 408 have survived, so it may help those working on the written text, too, if we find comparable images or assignments occur regularly in connection with some particular written source(s).
Figure 6 (above) came from Brit.Lib. Cotton Julius VI.
That manuscript relates to what is known as ‘computus’ – mathematical and religious works relating to calendrical calculations, including reconciling the lunar cycles with the solar year to determine the date of Easter.

Brit.Lib. MS Cotton Julius VI. Computistical texts and tables.
ff. 3r–8v: A metrical calendar (a version of the text known as the Metrical Calendar of Hampson), illustrated with the Labours of the Month and astrological[sic] symbols. ff. 9r–17v: Further computistical texts, tables, diagrams and a wheel linking months, lunar cycles and a T-O map (f. 15r), including a ‘Sator square’ palindrome written in Greek letters (f. 11r). ff. 18r–19v: A hymn beginning ‘Assunt o socii’ and excerpts from the Easter Sunday liturgy, beginning ‘Et valde mane’, were added in 12th-century hands to blank and erased folios. ff. 19r–71r: An imperfect Expositio hymnorum with a near-continuous Old English gloss. The text on f. 19r-v has been erased, but some initials are still visible. ff. 71r-72v: Three hymns for Trinity Sunday; ff. 72v-89v: Monastic canticles with an Old English gloss. f. 90r–v: The hymn ‘O genetrix aeterni’ and a fragment of the Latin poem beginning, ‘Ad mensam philosophie sitientes currite,’ both accompanied by neumes, were added in the last quarter of the 11th century.
Both the liturgical and the civil calendars began from Easter (falling in March or April) and the custom of dating documents or private letters by the saint’s day would continue to as late as the seventeenth century.

Maths texts don’t need pretty pictures.
The context in which we find FIG. 6, raises the uncomfortable possibility that the text which informed the Voynich ‘calendar’ diagrams might also be a mathematical treatise. Whether bound singly or in a miscellany, the Latins’ mathematical and mathematical-astronomical texts are typically chaste, devoid of illustrations other than a few terse diagrams which – in marked opposition to the Voynich calendar – were usually produced with compass and ruler.
In cases where pictures, as such, were desired, the usual practice seems to have been to include as excerpt or copy matter from a text of quite a different origin and type – as indeed was the case for BNF lat. 7351.
The chances are perhaps 50-50 that the Voynich calendar’s emblems have come from a very different source than that which provided the information for the diagrams. We see this too in copies made of the only other work to which the ‘calendar’ diagrams have been compared – the Libros made some decades after Scot’s death, under the auspices of Alfonso X (r. 1252-1284).
* * * *
Another instance of this practice comes from a manuscript which includes the earliest example I’ve seen (so far) of the ‘three-point’ head for Cancer: Oxford, Bodleian Laud. Misc. 644. It is given a ‘face’, and shows arcs drawn on the left and right on the creature’s thorax, gives the legs two ‘toes’ and forms the front legs in the same way as the rest . In this case, these constellation-figures were gained by copying from a copy of Aratus already not less than 200 years old and possibly 400 years old. As the catalogue says of folio 8 “”Good coloured drawings copying a model of 9th or 11th century, …” The manuscript which copies those older drawings was made in late thirteenth-century Bayeux.

The makers’ choosing so venerable an exemplar suggests a monastic library and scriptorium, and reverence for the oldest forms of image as most authenic, but it would be a mistake to suppose the manuscript is affected by intellectual conservatism. On the contrary, the rest of its content consists of what were, at that time, the most respected and most advanced mathematical works used in Europe.

Bodleian Laud Misc. 644 contains (not in order):
- Robert Grosseteste, ‘De sphaera‘ – an introductory text on astronomy.
- __________, ‘correctorius‘
- ________, ‘De lineis, angulis, et figuris; Mathematical reasoning in the natural sciences.
- Albumasar, ‘Flores astrorum‘ (in Latin trans.) Arabic title translates as “Book of the revolutions of the years.”
- Alfraganus, ‘Liber de aggregationibus [stellarum]’ (in Latin trans).
- Azarchel, –1100: Canones ad tabulas toletanas. (‘Toledan tables’)
- Boethius, ‘De institutione arithmetica’ – text and commentary. Latin.
- Boethius, ‘De institutione musica’ – text and commentary, Latin.
and of course the illustrated section:
Under ultra-violet light can be found an inscription informing us that, by the fifteenth century, Oxford, Bodleian Laud miscellany 644 was in the possession of Charles, duke of Orleans. Charles was the son of Valentina Visconti, through whom he had already inherited Asti, a town about 30 miles west of the Milan-to-Genoa road, and linked to it.

Picking up the thread…
And so, at last, we return to BNF lat. 7351, mis-called the ‘Liber Albandini’ which provided our ‘crocodile Scorpion’. Folio 41v shows these drawings (below), both described by the holding library as forms for Cancer.

Nonetheless (see Lippincott’s pdfs) the upper type is not rare as a form for Scorpius.
The manuscript was made in northern France during the 1300s, Its history before the fifteenth century is unknown but shortly before, or soon after the Voynich quires were inscribed, it was in the possession of Louis de Bruges, whose name might ring a bell if you read the post before last. This compilation’s content isn’t particularly religious, either. (catalogue entry).
It includes

- Pierre de Dacie, Kalendarium (Fragment)
- Albumasar (?), Liberimultitudinum (twice);
- plus ‘Sphere of life and death’; Astrological treaty in French; Text in Latin on critical days or the so-called ‘Egyptian days’; Correspondence between signs and months and ‘De Duodecim Zodiaci Signis Eorumque Effectibus’.
- The manuscript includes a removeable paper astrolabe (f.13v)

Pierre de Dacie’s text is no school primer. Sacrobosco would describe it as “algorismum vulgarem’.* meaning ‘ordinary mathematics’ or even ‘commercial maths’ as distinct from computus. Sacrobosco thought highly enough of de Dacie’s text to provide it with a commentary and, together, they proved an immensely popular text in western Europe.
Its primary notability is that it has a better method for extracting cube roots (better than the pre-existing method reported by Johannes de Sacrobosco).

Inferences
What these first examples have indicated is that, in Sicily at least, an association between the forms for Crab and prawn was ancient – ancient enough that they could have influenced astronomical images from the time of Eudoxus, who resided and studied for a time in Sicily.
We have also seen a ‘lobster’-like form, in association with the horse, dating from the time when Aratus made his poetic version of Eudoxus’ work. We have also seen that the style in which the Crab is pictured in Carolingian time, in Latin Europe, had preserved those earlier and more literal forms for Cancer.
Reverence for older forms and learning was a constant in the history of western Europe, with greater emphasis placed on pre-Christian forms as the ‘renaissance’ (so-called) began to flower in southern Europe during the fourteenth century.
Altogether, we must be prepared for the possibility that the Voynich ‘calendar’ diagrams as such may be informed by recent technical information, yet be provided central emblems gained from considerably older sources.
Cancer with a ‘three-point head’ and with arcs drawn on the thorax is a form as old at least as the eleventh century and possibly as old as the ninth century. By 1350, at least in northern France, the same manuscript in which we have a ‘crocodile’ Scorpius could accept for Cancer the form of both crab and prawn, these together or separately having referred to Sicily during the time of Greek, Carthaginian and Roman ascendancy, and an air-borne ‘lobster-like’ creature attested in Gaul no later than the first century BC.
It is entirely possible that there had existed copies of astronomical works, including globes, older than those used by the Carolingian court in which the constellations took a form different from those we now expect to see, and though one or two of the Voynich calendar emblems show evidence of what we might call ‘modernisation’, most of them including those which seem at first idiosyncratic, clearly have roots which are venerable at least and in some cases still evince a lineage decidedly ancient.
… continued next post…
Afterword
A little more on authors of the texts included in Oxford, Bodleian, Laud Misc. 644, manuscript made about thirty years after Michael Scot’s death. The authors of the mathematical sections:

GROSSETESTE. Scholar and Bishop of Lincoln, Robert Grosseteste particularly supported the Franciscan order (of which Roger Bacon became a member). Grosseteste “seems to have spent some time in France during the years 1208–14”. By.1229/30 he was teaching at Oxford, as reader in theology to the Franciscans, who had a community there by about 1224. He remained in that post until March 1235.Roger Bacon was his most famous pupil, and is said to have acquired an interest in scientific method from him. Those of his works included in Laud.Misc. 644 were written between 1220 to 1235.
∂ Works by Grosseteste not included in that volume:
- ‘De luce’. On the “metaphysics of light.” ( described as ‘the most original work of cosmogony in the Latin West’)
- ‘De accessu et recessu maris’. On tides and tidal movements. (although some scholars dispute his authorship).
- De iride’. On the rainbow.
ALBUMASSAR’ is Abu Ma’shar. (see end note)

‘ALFRAGANUS‘ is al-Farghani. Born in Uzbekistan in the 9thC AD. His ‘Jawami ilm Al-Nujum (A Compendium of Astronomy)* is thought to have been written in Egypt, becoming immediately and widely known among speakers of Arabic and Hebrew, and then being another among the works whose translation into Latin was made in Spain and credited to ‘Gerard of Cremona’.
- *Liber de aggregationibus scientiae stellarum et principiis celestium motuum, quem Ametus qui dictus est Alfraganus compilavit; cum figuris. cf. 524 AdBSB Clm 234.

AZARCHIEL. Toledo and Cordova. His work is commonly found together with that of Jacob ben Machir Ibn Tibbon’s ‘Treatise on the astrolabe’. See e.g. Oxford, Bodleian MS Laud Or 93. (1400-1475)
The Latin translation of the Toledan Tables ‘Canones ad tabulas toletanas’ is generally credited to the first Gerard of Cremona. Michael Scot said he had found these particularly helpful.

BOETHIUS was born in Italy in 480 AD, after the Roman empire’s capital had becme Constantinople and while the city of Rome lay under Ostragothic rule. He died in 524 (aged 44), but his ‘Arithmetica’ remained the standard text for teaching arithmetic and basic maths, until and even after the early fifteenth century.

∂ *Michael Scot died in c.1232. His studious interests were in mathematics, medicine-and-pharmacy and astronomy-astrology. The wiki article vastly exaggerates the magical- and under-states the astronomical and scientific content of Scot’s works for Frederick in Sicily, as well as conveying a false impression of Frederick as ’emperor’. In reality, Frederick reigned chiefly as king of Sicily and his court was regularly under interdiction, which prohibited any Latin Christian from engaging with him. HIs foray into diplomacy in the Holy Land was an effort to overcome those restrictions, whose results included refusal to acknowledge or use one of Frederick’s great accomplishments – sponsoring a Latin translation of al-Idrisi’s new astronomical-geography of the world, which took fifteen years under Roger, but of which no Latin version had been sent to Rome. Idrisi’s work became the foundation of a radically new form of education across North Africa when Idrisi finally returned there.

∂ According to N.G. Wilson, the first appearance of Aristotle’s biological writings in the West are Latin translations by MIchael Scot of an Arabic edition. According to Wilson, it was this work by Scot, rather than Thomas of Cantimpre, which formed the basis of the book de Animalibus by Albert of Lauingen though the opinion is not generally held:
- N. G. Wilson, A Descriptive Catalogue of the Greek Manuscripts of Corpus Christi College, Oxford (Oxford, 2011) pp. 20-21, Plates 43-46.
“‘Albumasar”‘s work, as ‘Flowers of astronomy’ began appearing in Latin, in print from about three generations after the Voynich quires were inscribed, but we know that 46 editions were printed between 1488-1506. These included illustrations, but we have no information about the source(s) used by the block-makers. As a rule they were commissioned from free-lance artists hired by individual printers, and once a printer had a convenient block, it might be used in any kind of text. Here, Cancer does have arcs on the thorax and lobster-like abdomen, but the tail has only three lobes, the abdomen has as neither legs nor swimmerets attached to it; both front legs are provided with claws, the antennae have a rippled edge, and though the head is given three points it is plainly based on that of the ‘prawn-like’ type.
