Voynich and Padua | Pal. lat. 742: The 30-Florin Appraisal — When a University Book Gets a Formal Market Value

A manuscript price can mean several different things.

What someone paid.

What someone asked.

What an official appraiser thought the book was worth.

Pal. lat. 742 gives us the distinction historians need.

The manuscript is a Bolognese Infortiatum made around 1290. By the late fourteenth century it belonged to Arduino Geremia, a Sicilian student documented at Pavia. Heidelberg’s catalogue reconstructs a transfer from Arduino to Cosimo Veronesi.

Then another note does something different.

On 9 August, the manuscript is formally valued:

Inforciatum domini Cosme de Veronixijs de Cicilia extimatum Florenis triginta auri.

Cosimo’s Infortiatum is appraised at 30 gold florins.

Heidelberg says it is quite possible that the appraisal was connected with Cosimo’s later sale of the manuscript.

Possible.

Not proven.

Pal. lat. 742 owns one of the most important provenance distinctions in the whole series: valuation is evidence of market value; it is not automatically evidence that a sale occurred at that price.

Quick Read

Pal. lat. 742 is a parchment Infortiatum with the ordinary gloss.
It was produced in Bologna around 1290.
The manuscript preserves marks of university pecia production.
Its first documented owner is Arduino Geremia, a student recorded at Pavia from 1392 to 1398.
Heidelberg reconstructs a transfer from Arduino to Cosimo Veronesi.
A separate note records the codex being appraised at thirty gold florins.
The appraiser’s name is recorded as Ambrosinus de Pergamo.
The catalogue says the appraisal may have been connected with Cosimo’s later sale of the book.
The appraisal itself does not identify the buyer or prove a completed sale.
Cosimo later brought the manuscript into Padua, probably in 1407.
By 13 August 1419, Antonius brought the same physical book into Padua, proving that ownership had changed by then.
The manuscript therefore separates acquisition, appraisal, probable later disposition and subsequent ownership.

Comparator Firewall

Pal. lat. 742 does not give us a sale receipt for thirty florins unless another document independently proves the transaction.

Its canonical job is to keep three monetary concepts separate: appraisal, asking price and completed purchase price.

The University Book Was a Market Asset

Pal. lat. 742 was produced within the Bolognese university-book system.

Its pages preserve pecia traces and correction marks.

This matters because a university codex is not simply intellectual property in the loose modern sense.

It is movable material property.

It can be bought.

Sold.

Pawned.

Inherited.

Appraised.

Carried across city borders.

Pal. lat. 742 lets us see the valuation machinery that makes such transactions possible.

Arduino Geremia and Cosimo Veronesi Form the Earlier Ownership Layer

Arduino Geremia is documented at Pavia as a student in the 1390s.

Heidelberg’s catalogue states that he transferred or sold both this Infortiatum and Pal. lat. 759 to Cosimo Veronesi.

The exact note is compact and has generated scholarly interpretation, but the ownership transition is supported strongly enough for the catalogue to present Cosimo as the later possessor.

This gives the manuscript an established value before the appraisal note even enters the story: it is already circulating among university-trained jurists.

The Appraisal Has Its Own Verb

The critical word is extimatum.

Appraised.

Estimated.

Valued.

The manuscript is not merely described as having cost thirty florins.

It is assigned a formal value of thirty gold florins.

Ambrosinus de Pergamo is named in connection with the appraisal.

This indicates an evaluative act separate from ordinary reading or ownership.

book + appraiser + valuation = market state.

Why Appraise a Book?

The surviving manuscript does not tell us with certainty why the appraisal was made.

Historically, valuation can serve several functions:

preparing a sale;
securing a loan or pledge;
dividing an estate;
assessing compensation;
valuing collateral;
recording institutional property.

Heidelberg says the appraisal may have been connected with Cosimo’s later sale.

That is plausible because by 1419 the book belongs to someone else.

But no surviving note in the appraisal itself names that later buyer or states that thirty florins were actually paid.

Appraisal Is Not Purchase Price

This distinction is easy to lose when numerical data are exciting.

A historian finds “30 florins” in the manuscript.

The temptation is to write “Cosimo sold the book for 30 florins”.

That would outrun the evidence.

The safest structure is:

known: the book was appraised at thirty gold florins;
plausible: the appraisal related to Cosimo’s later disposition of the book;
unknown: whether a sale occurred immediately, who bought it, and whether thirty florins was the final transaction price.

This is not pedantry.

It is how monetary evidence stays useful.

The Comparison With Pal. lat. 731 Clarifies the Difference

Pal. lat. 731 gives us an eighty-florin transaction in which buyer, intermediary and principal seller are identified.

Pal. lat. 742 gives us a thirty-florin appraisal.

Those are not interchangeable receipts.

Pal. lat. 731: money belongs inside a completed acquisition record.
Pal. lat. 742: money belongs inside a valuation record whose connection to a later sale remains probable but not demonstrated.

number alone does not tell you which economic event occurred.

Cosimo Brings the Book to Padua

Under ultraviolet/quartz-lamp examination, Heidelberg reports an earlier customs note on folio 1r reading Dominus Cosmas conduxit in Paduam.

Because Pal. lat. 731, 742 and 759 share the same owners, the note belongs to Cosimo’s documented Padua movement around 1407.

The manuscript therefore moves with Cosimo after the earlier Pavia ownership layer.

Again, movement and market value are separate fields.

13 August 1419: A New Owner Gives Us the Terminus for Cosimo’s Disposal

On 13 August 1419, a man named Antonius brings the manuscript into Padua.

The physical codex has therefore left Cosimo’s ownership by that date.

This gives us a useful bounded interval:

Cosimo owns the book → appraisal occurs → sometime before 13 August 1419 ownership changes → Antonius imports it into Padua.

The appraisal may sit inside that transfer process.

The exact sale receipt is missing.

Formal Valuation Creates a New Provenance Evidence Class

We can now add another edge type to the custody vocabulary.

purchase;
sale;
gift;
loan;
import;
export;
use;
valuation.

Valuation does not transfer title.

It changes the object’s market state.

A book that has been formally appraised is positioned for some economic or administrative operation even if that operation is not yet known.

Why This Matters to Voynich

The Voynich Manuscript’s later modern history includes explicit commercial transactions.

Its earlier history may have involved sale, pledge, valuation, inheritance or institutional transfer.

If archival research finds a price-like number next to a candidate manuscript description, Pal. lat. 742 warns us not to label it automatically a purchase price.

We must ask:

Who set the value?
Does the verb indicate appraisal or sale?
Is a buyer named?
Is payment recorded?
Does title change afterward?

The economic verb matters as much as the number.

What Pal. lat. 742 Adds

A Bolognese Infortiatum around 1290.
An earlier Arduino Geremia ownership state.
A later Cosimo Veronesi ownership state.
A formal appraisal at thirty gold florins.
A named appraiser, Ambrosinus de Pergamo.
A plausible—but not proven—connection between appraisal and Cosimo’s later sale.
An earlier Padua entry under Cosimo.
A 1419 Padua entry under a later owner, Antonius.
A precise distinction between valuation and completed transaction.

What It Does Not Add

No proof Cosimo sold the book for exactly thirty florins.
No buyer named in the appraisal note.
No exact date for the later sale.
No Voynich valuation record.
No basis for turning an appraised value into modern currency without context.

The Valuation Protocol

Identify the economic verb in the manuscript or document.
Separate extimatum from emi, vendidit and other transfer language.
Record appraiser, amount, currency and date.
Search for a later buyer or payment receipt.
Use subsequent ownership change to bound the possible transfer interval.
Never convert valuation into sale without a transfer edge.
Apply the same discipline to any monetary clue connected with Voynich provenance.

Evidence Ledger

Known

Pal. lat. 742 was produced in Bologna around 1290, passed from Arduino Geremia to Cosimo Veronesi, and was formally appraised at thirty gold florins. It was later imported into Padua under Antonius in 1419.

Strongly supported

Cosimo disposed of the manuscript before the 1419 Antonius entry.

Plausible

The thirty-florin appraisal was connected to Cosimo’s preparation to sell or otherwise transfer the book.

Open

The actual buyer, final transaction price and exact transfer date between Cosimo and the later owner.

Unsupported

Any claim that a thirty-florin sale is explicitly recorded or that this valuation has any direct relationship to Beinecke MS 408.

Research Sources

The Final Idea

Pal. lat. 742 gives us thirty gold florins.

But it refuses to give us permission to call them a sale price.

That refusal is valuable.

A number becomes historical evidence only when we preserve the operation it actually describes. In provenance, valuation is not transfer—and the difference can decide whether a chain is real or merely convenient.
