Wellcome MS.683 as a Voynich Comparator

Some manuscripts are designed as finished books.

Others become books by being used.

Wellcome MS.683 belongs to the second category.

It is a mid-fifteenth-century North-East Italian collection of medical recipes written on paper by two main hands and then extended by several contemporary hands. Its first thirty folios follow a head-to-toe therapeutic arrangement partly modelled on the ninth book of Rhazes’s Almansor. Later pages accumulate additional recipes. The final section explicitly extracts preparations from the Antidotarium of Bartolomeo da Montagnana.

This is not a perfectly unified authorial monograph.

It is a working medical object.

Wellcome MS.683 matters to Voynich because it shows how a fifteenth-century practical manuscript can combine inherited authorities, local recipes, multiple hands, additions, marginal notes, changing organisation and physical damage while remaining functional.

Quick Read

Wellcome Collection reference: MS.683.
Date: mid fifteenth century.
Probable origin: North-East Italy.
Material: paper.
Extent: 39 leaves, with damage and losses affecting parts of the volume.
The main recipe collection on ff. 1r–30v follows a head-to-toe medical arrangement and partly draws on Rhazes’s Liber nonus ad Almansorem.
The manuscript does not simply copy Rhazes: many sections contain unidentified commentary and/or recipes, and later chapters diverge.
Recipes on ff. 31r–35v were added by the second scribe and other contemporary hands.
Ff. 36r–37v contain excerpts from Bartolomeo da Montagnana’s Antidotarium, including ointments, plasters, oils, powders, pills and pessaries.
F. 38r-v adds still more recipes in another cursive hand.
Multiple readers added marginal notes and nota signs.
The manuscript therefore gives Voynich research a real control for an accretive technical book: a codex whose informational architecture changed through use.

Comparator Firewall

MS.683 is not proposed as a Voynich source, exemplar or decoded genre. It is a control for manuscript behaviour: how practical medical information can be copied, reorganised, extended and repaired by several users.

The chronological and regional proximity makes the comparison useful.

It does not create genealogy.

The First Lesson: A Working Book Does Not Need One Authorial Voice

Modern publishing trains us to think of a book as a closed product.

One author.

One edition.

One final sequence.

One table of contents.

MS.683 resists that model.

The Wellcome catalogue identifies two main hands in the core text and several additional mid-fifteenth-century Italian cursive hands in the appended material. Readers also supplied marginal notes.

The manuscript therefore contains several layers of agency:

an organiser who chose a head-to-toe medical framework;
scribes who copied and adapted material;
users who added recipes;
readers who marked useful passages;
later binders and conservators who altered the physical object.

Not every layer needs the same purpose.

This is directly relevant to Voynich, where we already know that original production, later foliation, month names, ownership marks, binding and marginalia belong to different historical moments.

A manuscript can be one object without being one event.

The Head-to-Toe Order Is a Retrieval System

The main receptarium is organised broadly a capite ad calcem: from head downward through the body.

This is not merely a literary convention.

It is an interface.

A practitioner with a problem in the head begins near one end.

A disorder lower in the body belongs farther along.

The book turns anatomy into navigation.

This provides an important control for Voynich sectioning. A sequence of visually different units might reflect a retrieval path rather than a narrative progression.

Order can answer a user question.

It does not have to tell a story.

Authority Is Borrowed, Then Reworked

The core of MS.683 partly follows the chapter organisation and beginnings of Rhazes’s Liber nonus ad Almansorem.

But it is not simply a clean copy of Rhazes.

The Wellcome description notes that many chapters begin like the corresponding Rhazes chapters while the text that follows consists of unidentified commentary and/or recipes. Later chapters diverge more strongly.

This is a beautiful example of practical transmission.

An authoritative framework can survive while its contents change.

borrowed architecture → local filling → later addition

The manuscript can remain recognisably connected to an inherited medical tradition without reproducing one source word for word.

That sets a high bar for Voynich source claims.

If Voynich adapts a known medical source, we should expect a transformation mechanism—not necessarily exact copying, but enough repeated structure to distinguish adaptation from coincidence.

The Manuscript Moves From Authority to Experience

The later additions are where MS.683 becomes especially human.

On f. 31r appears a recipe introduced as an experimentum for treating a fistula.

The word matters because practical recipe culture often preserves knowledge through reported use, testing, experience and local authority as well as through canonical books.

A medieval medical notebook can therefore contain several epistemic levels at once:

ancient authority;
university authority;
copied commentary;
local practice;
named experiment;
personal annotation.

The boundaries between those levels may be visible through script, position or rubric.

They may also blur.

This is exactly why a manuscript should be read stratigraphically.

Bartolomeo da Montagnana Enters as Extracted Working Knowledge

Ff. 36r–37v explicitly contain recipes extracted from the Antidotarium of Bartolomeo da Montagnana.

The opening rubric identifies them as recipes extracted from Montagnana’s large antidotary.

This is a remarkable transmission edge.

A prominent Paduan physician writes or compiles pharmaceutical knowledge.

A practical manuscript extracts selected preparations.

The selections include different dosage/preparation forms: ointments, plasters, patches, oils, powders, pills and pessaries.

Knowledge has moved from scholarly authority into a working recipe environment.

This is one of the clearest reasons to avoid treating “university medicine” and “practical recipe culture” as separate worlds.

Extraction Changes the Unit of Knowledge

When a practitioner copies one useful recipe from a larger treatise, the unit changes.

In the source book, the recipe belongs to an organised argument or collection.

In the working receptarium, it becomes portable.

It can sit beside recipes from other authorities.

It can lose some context.

It can gain a local heading.

It can be modified.

It can become memorable because a user marked it as successful.

Copying a recipe is not merely copying text. It is re-hosting an executable unit inside a new information system.

This Helps Explain Why Technical Books Can Look Patchy

A working manuscript grows according to need.

Useful blank space invites additions.

A new owner may add a remedy.

A student may copy a respected professor.

A practitioner may mark one passage.

A later reader may supply a synonym.

The physical codex becomes an accumulation of decisions.

This is different from saying Voynich must be a working notebook.

It gives us a control for features that otherwise look suspicious:

local changes in script;
different kinds of entries;
section transitions;
marginal additions;
mixed authorities;
partial reorganisation;
blank or damaged space;
non-uniform density.

A heterogeneous manuscript can be functional rather than incoherent.

Paper, Watermarks and Production Geography

MS.683 is written on paper rather than parchment.

The Wellcome catalogue records several watermarks, including bull’s-head types and a triple-mount watermark comparable to a Vicenza example dated 1442.

Watermark comparison contributes to the North-East Italian localisation.

This gives us an important provenance lesson.

Geography becomes stronger when different evidence layers converge:

script;
paper;
watermarks;
language;
textual authorities;
local transmission.

Voynich localisation needs the same kind of convergence.

One Italian-looking drawing is weaker than independent material, palaeographic and textual indicators pointing to the same region.

Damage Does Not Erase Function

MS.683 is not pristine.

One folio is fragmentary.

The collation has losses.

The current binding is modern.

Yet enough physical and textual evidence survives to reconstruct large parts of its history.

This is another useful control for Voynich.

An incomplete manuscript can still support robust conclusions about organisation and use.

At the same time, losses create local uncertainty.

Damage lowers confidence where evidence is missing. It does not license invention.

A Receptarium Is Not Necessarily a Clean Recipe Database

Modern data thinking encourages us to imagine recipes as neatly normalised records.

Disease.

Ingredients.

Quantity.

Method.

Dose.

Medieval working manuscripts can be messier.

Some instructions are abbreviated because the intended reader already knows the missing steps.

Some ingredients use synonyms.

Some measures are conventional.

Some additions assume context from an earlier page or oral practice.

The manuscript can therefore contain tacit knowledge.

This is crucial when testing Voynich medical hypotheses.

Absence of an obvious modern-style instruction field does not immediately disprove practical use.

But the theory must still explain how an intended reader could recover enough information to act.

What MS.683 Can Legitimately Teach Voynich Research

A fifteenth-century medical book can grow through accretion rather than one authorial plan.
Several contemporary hands can contribute without making the manuscript meaningless.
An inherited chapter framework can survive while local content changes substantially.
Practical recipes can be extracted from major authorities and re-hosted in working collections.
Head-to-toe order is a retrieval interface, not necessarily a narrative.
Marginal notes and nota signs are evidence of use.
Paper, watermarks and script can combine to support regional localisation.
Damage and missing leaves create structured uncertainty without destroying all reconstructability.
Practical recipe books can preserve tacit knowledge and abbreviated execution.
Heterogeneity can be a sign of use history rather than incoherence.

What MS.683 Does Not Prove

that Voynich is a receptarium;
that Voynich was produced in North-East Italy;
that its sections were added by different practical users;
that Currier A/B corresponds to different recipe hands;
that Voynich’s star entries are medical recipes;
that its plant pages or vessels derive from Rhazes or Montagnana;
that every irregularity should be explained as manuscript accretion;
that missing information can be supplied from an imagined oral tradition without evidence.

A Working-Book Test for Voynich

Map physical boundaries: quire, bifolium, folio, foldout.
Map handwriting or hand-style variation independently.
Map textual regimes such as Currier, labels and paragraphs.
Map visual regimes independently.
Test whether abrupt changes align with physical insertion boundaries.
Search for later-looking additions, local formulae or marginal behaviour.
Compare the alignment against known accretive medical manuscripts such as MS.683.
Keep an accretion hypothesis only where it predicts multiple independent layers.

This prevents “different-looking page” from becoming “different author” by reflex.

Student Lens: Books Can Have Histories Inside Them

Primary: compare a new workbook with one used by several family members. Notes, corrections and additions reveal different moments.

Lower Secondary: give students a mixed notebook and ask them to identify which sections were copied from a textbook, which were personal notes and which were later additions.

Upper Secondary: reconstruct a document’s chronology from handwriting, paper, margins and cross-references without relying on content alone.

JC and adult readers: model the manuscript as an append-only knowledge store in which authority, local practice and later annotation coexist with different provenance.

The Final Idea

MS.683 is valuable because it looks less like an ideal book and more like knowledge living in the world.

Authority enters.

A scribe adapts it.

A second hand adds something useful.

Another practitioner extracts a respected Paduan recipe.

A reader marks a passage.

A leaf is damaged.

The book keeps working.

If Voynich is a practical knowledge object, its irregularities may have to be explained historically rather than smoothed away statistically. MS.683 shows us what a real working manuscript looks like when use itself becomes part of authorship.
