One of the easiest ways to reject the Padua hypothesis is to compare Voynich only with the Carrara Herbal.
One of the easiest ways to rescue the Padua hypothesis is to ignore the Carrara Herbal completely.
Both moves are wrong.
Padua produced more than one kind of book.
A court manuscript, a university study book, a collection of consilia, a miscellany, a monastic codex and a practical medical compilation can all emerge from the same city while looking profoundly different.
If Voynich is to be tested against Padua, we need the full manuscript ecology—not one beautiful courtly control treated as the local template.
Quick Read
- The Carrara Herbal represents one securely Paduan book type: an elite, illustrated, court-associated medical manuscript.
- Research from the University of Padua on Paduan university manuscripts shows a different fifteenth-century book population designed for specialised academic readers.
- These university books had material and organisational features shaped by study and consultation rather than court display.
- The fifteenth-century Paduan corpus includes a notable spread of miscellaneous codices containing several texts needed for study.
- Such miscellanies could collect consilia, quaestiones, legal, medical and philosophical materials.
- This creates a historically real Paduan model in which multiple technical units can coexist inside one codex.
- A British Library manuscript copied by a monk of Santa Giustina in Padua provides a separate fifteenth-century control for local book production and later movement to Venice.
- None of this proves that Voynich is a Paduan university miscellany.
- It does mean that “Voynich does not look like the Carrara Herbal” cannot by itself exclude Padua.
The Single-Comparator Trap
The Carrara Herbal is exceptionally valuable because its Paduan identity is secure.
That very security creates a trap.
We can begin treating it as though it defines what a Paduan manuscript must look like.
But a city is not a style sheet.
Books are shaped by:
- receiver;
- function;
- budget;
- institution;
- language;
- available exemplar;
- scribe;
- artist;
- production speed;
- expected lifetime of use.
A luxury court book and a student’s technical volume can belong to the same intellectual environment while sharing very little surface appearance.
The Court Book
The Carrara Herbal gives us the elite pole.
It is large.
Illustrated.
Heraldically marked.
Connected to Francesco Novello’s court.
Its textual tradition is identifiable.
Its vernacularisation itself participates in cultural display and accessibility.
This tells us what one high-investment Paduan medical manuscript could be.
Voynich does not visibly occupy the same social interface.
That difference should remain evidence.
The University Book Has a Different Job
Research on Paduan university manuscripts emphasises that late-medieval university culture produced books with precise material and functional requirements for specialised readers.
The user is not primarily a prince being shown prestige.
The user may be a student, lecturer, jurist, physician or philosopher trying to retrieve arguments and technical material.
That changes the interface.
court book optimises display and patronage; university book optimises study, comparison, consultation and reuse.
The Paduan Miscellany Is a Major Control
University of Padua research on the “tools of knowledge” in Paduan manuscripts identifies one especially important feature of fifteenth-century university production: the broad diffusion of miscellaneous codices.
These books could preserve different texts needed for study inside one physical codex.
The research specifically mentions collections of:
- consilia;
- quaestiones;
- legal material;
- medical material;
- philosophical material;
- larger works assembled alongside other study units.
This is one of the most important structural comparators yet identified for Voynich.
Not because Voynich is therefore a university miscellany.
Because a Paduan technical codex did not have to represent one modern subject or one continuous text.
Mixed Codex Does Not Mean Random Codex
A miscellany can contain multiple works without being arbitrary.
The selection can be organised around the needs of one reader.
A medical student may need theory, questions, consilia and practical material.
A teacher may need several authorities.
A practitioner may add new material over time.
The codex becomes a personal or institutional stack.
multiple textual populations can share one receiver even when they do not share one genre.
This is a much better model for testing Voynich’s apparent section changes than assuming six modern topics were intentionally bound as six textbook chapters.
The Voynich “Six Sections” May Be an Interface Error
Voynich is commonly divided into herbal, astronomical, zodiacal, biological or balneological, pharmaceutical and recipe sections.
These are descriptive labels created by modern observers.
A university-miscellany control asks whether the better unit might be:
- several copied texts;
- several teaching units;
- a core text plus additions;
- separate functional modules;
- materials gathered for one specialist receiver.
This changes the analysis dramatically.
Differences in vocabulary or layout between sections no longer necessarily demand different languages or meanings.
They may reflect different source units.
Currier A and B Become More Interesting
Voynich scholarship has long recognised statistical differences commonly labelled Currier A and Currier B.
A miscellany model does not solve those differences.
It gives them another historical comparator.
If different source units, scribes or teaching materials were assembled into one codex, we might expect textual populations to vary.
The test then becomes codicological.
Do changes in textual statistics align with:
- quires;
- hands;
- layout;
- image families;
- production sequence;
- later reordering?
If not, the miscellany explanation weakens.
A Study Book Should Reveal Retrieval
University manuscripts are not simply piles of text.
They have to be usable.
This brings back the retrieval problem.
If Voynich was a specialist study book, how did its reader navigate it?
Possible structures include:
- visual section recognition;
- repeated paragraph openings;
- labels;
- stable page grammar;
- quire memory;
- internal cross-reference systems;
- an index now lost;
- receiver familiarity with the sequence.
The fact that modern readers cannot see the retrieval system does not mean one never existed.
But any university-book interpretation must reconstruct it.
The Illustration Problem Remains
Voynich is heavily visual.
Many university study books are much more text-centred.
This is a genuine mismatch.
We should not erase it.
A Paduan university-book hypothesis must explain why images are so structurally central.
Possible reasons could include a discipline requiring visual identification or diagrams.
But that claim must be demonstrated page by page.
The Absence of Obvious Latin Is a Bigger Problem
University technical manuscripts commonly use Latin, sometimes alongside vernacular material.
Voynich’s main script does not reveal an accepted Latin text.
Therefore a Paduan university context cannot be invoked without addressing the language problem.
Possible models include abbreviation, cipher, constructed notation, vernacular transformation or another system.
None is currently proven.
A plausible book type does not solve an unknown script.
Santa Giustina Gives Us a Separate Fifteenth-Century Paduan Book Route
British Library Add MS 30154 provides a useful non-medical control.
The catalogue describes a fifteenth-century paper manuscript written by Eusebius, a monk of Santa Giustina in Padua.
A note records the book as belonging to the Congregation of the monks of Santa Giustina and later assigned to the monastery of San Giorgio Maggiore in Venice.
This gives us a concrete object route:
Padua monastic production/ownership → Venetian monastic custody.
It has nothing to do with Voynich content.
That is why it is useful.
It proves that fifteenth-century books could move through institutional routes from Padua to Venice without needing Carrara court ownership.
The Court-to-University Contrast
We can now define two Paduan poles.
Court Book Pole
- elite patronage;
- heraldry;
- luxury illustration;
- prestige;
- known commission environment;
- high visual finish.
University Working-Book Pole
- specialised reader;
- study function;
- multiple texts;
- consilia and quaestiones;
- consultation;
- modular organisation;
- possible accumulation over time.
Voynich does not fit cleanly at either pole.
That is useful.
It means we should test whether it occupies a third category rather than force it into one.
A Third Possibility: The Specialist Private Compilation
The comparator library suggests another manuscript job.
A specialist can assemble a private working codex that borrows from university knowledge without being an official university textbook.
This kind of book could:
- mix sources;
- omit obvious patronage;
- use dense specialist shorthand;
- be visually structured for one user;
- change over time;
- sit outside conventional literary presentation.
This remains a hypothesis class, not a Voynich identification.
But it is historically more realistic than treating every manuscript as either luxury commission or formal textbook.
What This Changes in the Padua Test
We should no longer ask only:
Does Voynich resemble the Carrara Herbal?
We should ask:
- Which Paduan book population is the correct control?
- Does Voynich behave like a court book, study book, miscellany, practical compilation or something else?
- Do its quire boundaries align with textual or functional modules?
- Does its page architecture support retrieval by a specialist receiver?
- Are its visual systems more central than in ordinary university manuscripts?
- Can a Paduan production hypothesis explain both its similarities and its major mismatches?
What the University-Manuscript Control Can Support
- Fifteenth-century Padua produced specialised books for academic readers.
- Paduan university manuscript culture included miscellanies with multiple technical texts.
- Medical, philosophical and consilia materials could coexist within such study environments.
- A Paduan manuscript did not need to look like a Carrara luxury commission.
- Post-1405 Padua retained manuscript and institutional book culture under Venice.
What It Cannot Support
- that Voynich was a university textbook;
- that its sections are separate copied texts;
- that Currier A and B correspond to a miscellany structure;
- that its unknown script is student shorthand;
- that Santa Giustina or another Paduan institution owned it;
- that mixed content proves Padua.
The Best Next Test
The manuscript-production question now has a concrete next step.
Build a control corpus of securely fifteenth-century Paduan university manuscripts and compare them with Voynich across:
- quire structure;
- page dimensions;
- ruling and pricking;
- text density;
- paragraph architecture;
- miscellany boundaries;
- marginalia;
- illustration frequency;
- abbreviation;
- retrieval aids;
- binding and later reordering.
Then compare the same variables with Bologna, Ferrara, Venice, Lombardy and Central European controls.
Only then can “Paduan manuscript behaviour” become a discriminating claim.

The Final Idea
Padua did not produce one kind of manuscript.
That sounds simple.
It changes the hypothesis profoundly.
The Carrara Herbal tells us what a Paduan court could commission. University miscellanies tell us what specialised Paduan readers could use. Voynich must now be tested against the whole manuscript ecology—and it must still explain why it is unlike every known control in some of its most important features.
