Morgan M.873 showed us the world before the remedy.

The next manuscript changes the architecture.

It gathered plants, animals, minerals, extracted substances and manufactured materials into a visual inventory. It made the medical supply universe searchable, but it rarely carried the reader through the complete sequence from recognised substance to executed treatment.

The Carrara Herbal, British Library Egerton MS 2020, does not merely point towards medicinal matter. It joins that matter to an extensive pharmacological text, translates inherited medicine into a local language, surrounds it with unusually accomplished illustrations and installs the result within the political and intellectual world of late-fourteenth-century Padua.

This is where the book of substances becomes a book of meanings.

Morgan M.873
What materials can enter medicine?
Carrara Herbal
What properties and actions are attributed to them,
and how can that knowledge be installed in Padua?

The Carrara Herbal therefore occupies a different position from Morgan.

Morgan maps the inputs.

The Carrara Herbal begins to expose the medical operating system.

The object

The British Library dates Egerton MS 2020 to approximately 1390–1404. It contains a fourteenth-century Italian translation associated with Jacopo Philippo of Padua, probably made through a Latin version of a pharmacological work originally written in Arabic by the author known in Latin Europe as Serapion the Younger. The manuscript was produced for Francesco Novello da Carrara, lord of Padua from 1390 until the Venetian conquest in 1405. (British Library Archives)

The work from which it descends was the Kitāb al-adwiya al-mufrada—the Book of Simple Medicines—associated with Ibn Sarābī, described in scholarship as an Arabic-speaking Christian physician working in al-Andalus. A Latin translation was circulating in Italian medical schools by around 1290. (ResearchGate)

The transmission route can be represented as:

Arabic pharmacology
→ Latin translation
→ Italian medical-school circulation
→ Paduan vernacular translation
→ Carrara court manuscript
→ illustrated local knowledge system

This was not simply the copying of an old herbal.

It was the relocation of an international medical tradition into a particular city, language and political environment.

A book about simples

A simple medicine was a substance considered before its incorporation into a more complex compound.

It might come from:

• a plant;
• an animal;
• a mineral;
• a gum or resin;
• a seed, root or fruit;
• a processed but individually recognised substance.

The word simple did not necessarily mean easy, weak or uncomplicated.

It identified a medicinal material as a unit.

That unit could still possess several properties, produce different effects under different conditions and require careful preparation.

The Carrara Herbal’s underlying pharmacological world therefore begins with a structured question:

What does this substance do?

Morgan M.873 helped locate the substance within the material universe.

The Carrara Herbal adds another series of relationships:

substance
→ quality
→ action
→ affected body
→ possible use
→ possible danger

The visual object now acquires pharmacological behaviour.

From inventory to semantics

Consider the difference between two kinds of entry.

An image-and-label system may tell the reader:

This is the object called X.

A pharmacological entry can tell the reader:

X has these qualities.
X acts in these ways.
X may affect these bodily conditions.
X may be prepared or applied under these circumstances.

The second is not necessarily a complete prescription.

But it moves significantly closer to medical reasoning.

The Carrara Herbal is therefore not merely more complete than a picture collection. It is a different type of machine.

The two systems can cooperate.

They should not be mistaken for one another.

Why the translation matters

The Latin translation of Serapion could circulate within learned medicine.

But the Carrara Herbal was produced in a Paduan vernacular with Venetian inflections rather than remaining only in university Latin. The British Library places the manuscript within a wider late-fourteenth-century Paduan culture in which Francesco Novello gathered learned men who produced books in both Latin and the local language. (British Library)

Translation changed more than vocabulary.

It changed access.

A medical work in Latin primarily entered one reading corridor:

university
→ cleric
→ learned physician
→ Latin-literate court reader

A vernacular version could enter a wider and partly overlapping corridor:

court household
→ educated administrator
→ local practitioner
→ apothecary environment
→ non-university elite reader

This does not mean the book became a popular household handbook.

It remained an expensive and elaborate court manuscript.

But the use of the vernacular moved pharmacological knowledge closer to the language of the city.

The knowledge had crossed from one linguistic operating environment into another.

Translation is not neutral transport

A translated medical work does not simply replace one word with another.

The translator must negotiate:

• substances whose names have travelled through Arabic and Latin;
• materials with several regional names;
• concepts built inside inherited medical theory;
• plants that may not be locally familiar;
• distinctions that do not map neatly between languages;
• technical terms with no exact vernacular equivalent.

The translation pathway may therefore contain several transformations:

[
\text{Arabic object-name}
\rightarrow
\text{Latin medical term}
\rightarrow
\text{Paduan expression}
\rightarrow
\text{reader’s material understanding}
]

Every transition can preserve knowledge.

Every transition can also introduce ambiguity.

This makes the illustrations important.

The image can help hold the translated word near a visible object, although it cannot guarantee that every reader will correctly match the painting to a dried or processed shop substance.

The manuscript combines three stabilisers:

inherited authority
+
vernacular language
+
visual representation

That is a much stronger interface than any one component alone.

The page as a medical assembly

A Carrara Herbal page brings several systems together.

At the upper level sits the pharmacological text.

Below or around it, the painted plant extends across the parchment. Roots, branches, flowers, fruit, leaves and tendrils may occupy substantial areas of the page. The illustrations are among the most accomplished medical images associated with the period, and the British Library explicitly identifies their exceptional skill. (British Library)

The page therefore operates simultaneously as:

medical text
botanical representation
vernacular translation
courtly artwork
indexable manuscript entry

This is not decorative text with a plant added.

Nor is it a plant portrait with an incidental caption.

The page was engineered to let verbal and visual knowledge coexist.

The two-channel system

The textual channel provides:

• inherited names;
• medical qualities;
• actions;
• therapeutic associations;
• organisation through chapters and entries.

The visual channel provides:

• overall plant habit;
• distinctions among leaves, fruit and flowers;
• visible parts;
• a memorable spatial form;
• a means of differentiating neighbouring entries.

Together they create a dual representation:

[
\text{Medical substance}

\text{what authorities say it does}
+
\text{how the manuscript makes it visible}
]

The channels are related but not interchangeable.

A beautiful image cannot supply dose.

A pharmacological text cannot always ensure physical recognition.

Their conjunction reduces some kinds of uncertainty while leaving others unresolved.

The plant is no longer merely a symbol

The Carrara Herbal is especially notable for the variety and naturalistic force of many of its plant illustrations.

Its cucumber and melon images, for example, have been studied for the way they preserve identifiable differences among cultivated forms. Later research has described the manuscript’s cucumber image as exceptionally accurate for the medieval period. (PubMed Central (PMC))

This does not mean every image was painted directly from a living specimen.

The manuscript contains stylistic diversity, inherited visual traditions and different representational strategies. Scholarship places it within a complex meeting point of imitation, observation, courtly art and medical knowledge rather than treating it as a modern field guide produced by uniform botanical observation. (ResearchGate)

The important development is not a simple transition from “bad medieval image” to “scientifically accurate image.”

It is the expansion of what a medical plant picture could do.

Some illustrations could now carry:

• inherited identity;
• local visual observation;
• therapeutic significance;
• aesthetic prestige;
• evidence of the patron’s command of knowledge.

The plant had become part of several systems at once.

Padua as the execution environment

The Carrara Herbal could not have emerged from text alone.

Its production required several Paduan systems to converge.

University
+
Carrara court
+
medical translators
+
scribes
+
painters
+
manuscript workshops
+
pharmacological sources
+
local linguistic culture

The University of Padua supplied an established environment in which Arabic medical works translated into Latin could circulate, be taught and interpreted.

The court supplied patronage, political purpose and the resources required for a luxury manuscript.

The city supplied artists, scribes, learned intermediaries and a living vernacular.

The commercial-medical environment supplied the material reality behind the substances.

The Carrara Herbal was produced where these systems overlapped.

The University and the court were not duplicates

The University organised knowledge through:

• lectures;
• authoritative texts;
• disputation;
• professional formation;
• Latin literacy;
• medical theory.

The Carrara court organised knowledge through:

• patronage;
• collection;
• representation;
• prestige;
• dynastic identity;
• vernacular cultural production.

The same pharmacological tradition could mean something different in each environment.

Inside the University, Serapion was part of learned medicine.

Inside the Carrara Herbal, Serapion also became part of a prince’s representation of rule.

Scholarship interprets the manuscript as connecting Francesco Novello to an ideal of the ruler capable of protecting the moral and physical health of Padua—the image of a form of physician-prince. (ResearchGate)

The manuscript therefore performs two operations simultaneously:

It describes medicines.
It describes the kind of ruler who possesses,
translates and preserves medical knowledge.

Medicine becomes government

A ruler does not need personally to compound every remedy for a medical manuscript to serve political meaning.

Health is already a governing problem.

A city requires:

• food supply;
• water;
• sanitation;
• hospitals and charitable care;
• physicians and surgeons;
• apothecaries;
• responses to epidemic disease;
• protection of commercial and institutional continuity.

A prince associated with medical knowledge can be represented as someone capable of understanding and maintaining the body of the city.

The Carrara Herbal transforms pharmacology into an image of competent rule.

healthy substance
→ healthy body
→ healthy household
→ healthy city
→ legitimate ruler

This does not make the manuscript mere propaganda.

Its medical content remains real and substantial.

But the courtly setting gives that content another function.

The book could preserve therapeutic knowledge while also presenting the Carrara lordship as learned, protective and civilised.

The manuscript’s Production Energy

The Carrara Herbal is an expensive convergence object.

Its production required:

[
P_E =
A + T + L + V + I + P + C
]

Where:

• (A) = access to Arabic-derived pharmacology;
• (T) = translation through Latin into Paduan;
• (L) = learned medical interpretation;
• (V) = visual design and illustration;
• (I) = institutional support;
• (P) = patronage;
• (C) = coordination.

None of these components alone explains the manuscript.

The object appears when all become simultaneously available.

This is why its Paduan location matters.

Late-fourteenth-century Padua already contained the required convergence: the University, the Carrara court, learned medicine, vernacular literary production and highly capable manuscript artists. The British Library describes the cultural scene as driven by precisely this combination. (British Library)

The manuscript was costly.

But it did not require an impossible civilisation.

Its production energy lay within the city’s operating envelope.

Morgan M.873 and the Carrara Herbal

The relationship between Morgan and Carrara is best understood functionally rather than as a proven direct copying route.

Morgan M.873 establishes the broad material universe:

plants
animals
minerals
extraction
manufacture
medical supply

The Carrara Herbal installs another layer:

qualities
actions
medical interpretation
vernacular explanation
courtly ownership
political meaning

Together they reveal that materia medica had at least two separate maps.

The material map

Where does the substance come from?

How does it enter circulation?

What physical object is being named?

The pharmacological map

What does the substance do?

What qualities are attributed to it?

How does it relate to the body?

The maps need one another.

A correct medical theory attached to the wrong physical material is dangerous.

A correctly identified material without pharmacological guidance remains incomplete.

The larger system therefore requires:

[
\text{Material identity}
\times
\text{Pharmacological meaning}
]

Morgan strengthens the first term.

Carrara strengthens the second.

Masson 116 and the Carrara Herbal

Masson 116 preserved a visual medical corpus with little of the explanatory text apparently anticipated by its page design.

The Carrara Herbal shows the opposite condition.

Its images and substantial text were successfully installed together.

Masson:
the image layer survives while the fuller textual layer remains absent
Carrara:
image, text, translation and patronage converge in one completed system

This comparison is important because it demonstrates that medieval medical manuscripts were not defined by one fixed architecture.

Their components could be joined differently:

• image without extended text;
• text with limited illustration;
• image and caption;
• text and image in a coordinated court manuscript;
• later copies preserving one layer while altering another.

The manuscript world was modular.

Carrara is one of its most elaborate assemblies.

The book does not reach the entire treatment runtime

The Carrara Herbal moves much further towards executable medicine than Morgan or Masson.

But even Carrara does not preserve everything required for medical practice.

A treatment still requires:

patient examination
→ diagnosis
→ selection of substance
→ quality judgement
→ dose
→ preparation
→ combination
→ timing
→ administration
→ observation
→ correction

A pharmacological description of a simple can support several of these decisions.

It does not replace them all.

Much of the remaining knowledge would have lived in:

• medical training;
• physicians’ experience;
• apothecary practice;
• antidotaries and formularies;
• recipe collections;
• household knowledge;
• oral instruction;
• professional coordination.

The Carrara Herbal therefore closes part of the apparent void.

It does not close the entire void.

The human runtime around the manuscript

The book implies several distinct users.

Jacopo Philippo or the translating scribe

He connects inherited Latin medical material to the Paduan vernacular. The British Library cautiously describes him as copying and probably translating the work. (British Library)

The medical interpreter

Someone must ensure that the pharmacological tradition remains sufficiently coherent during translation.

This role may overlap with the translator, but the functions should not automatically be treated as identical.

The artists

They translate named substances into visual forms.

Different images may depend on inherited models, local observation or workshop practice.

Francesco Novello

As commissioner and courtly owner, he supplies patronage and political context.

He need not be the manuscript’s everyday medical operator.

The physician

A trained physician could connect the text’s account of simples to diagnosis and therapeutic selection.

The apothecary

The apothecary could connect the named substance to physical stock, quality, preparation and compound production.

The court household

The manuscript could be read, displayed, discussed, preserved or used as evidence of the court’s learning.

These users do not share one identical relationship with the book.

Commissioner ≠ translator
Translator ≠ painter
Painter ≠ physician
Physician ≠ apothecary
Owner ≠ daily operator

Separating them prevents the manuscript from being assigned a simplistic single purpose.

The later Roccabonella branch

The Carrara Herbal did not end with its original court environment.

The Roccabonella Herbal, produced around the middle of the fifteenth century and preserved in Venice, reproduced images from the Carrara Herbal with modifications while retaining much of their visual quality. (PubMed Central (PMC))

This establishes an important transmission edge:

Carrara visual system
→ later copying and adaptation
→ Roccabonella Herbal

The original manuscript therefore became more than a finished court object.

It became a source.

Its illustrations could be extracted from their initial political setting and installed in another medical book.

Again, the components prove modular:

court ownership can disappear
while the plant image continues travelling

The manuscript’s medical and visual knowledge outlived the precise circumstances of its commission.

1405: the runtime breaks before the book does

The Carrara Herbal was produced during Francesco Novello’s rule.

In 1405, Padua fell to Venice. Carrara government ended, and Francesco Novello and members of his immediate family died in Venetian custody soon afterward. (Treccani)

This gives the manuscript an unusually sharp historical boundary.

1390–1404:
court commission, production and installation
1405:
political operating environment collapses
after 1405:
the manuscript survives beyond its original regime

The book’s parchment did not need to be destroyed for its first runtime to end.

Its commissioner lost his city.

The courtly network changed.

Ownership, access and purpose could be reconfigured.

The manuscript moved from being an active product of Carrara rule to being a surviving object from a terminated political system.

This is the difference between object continuity and runtime continuity.

The Explanatory Energy rises

Before 1405, the manuscript could be understood through its surrounding environment:

Carrara prince
+
Paduan court
+
University
+
translator
+
artists
+
medical readers
+
local language

After the disappearance of that world, later observers encounter:

an illustrated Paduan pharmacology
without its original court

The manuscript itself has not become more complicated.

Its lost neighbours make it more difficult to explain.

That is the rise in Explanatory Energy.

Modern research must reconstruct relationships that were once physically present:

• why this work was selected;
• why it was translated;
• why the vernacular mattered;
• why the images were so ambitious;
• how medicine served Carrara identity;
• who could move between the book and practical treatment;
• how the object survived the fall of its commissioner.

What the Carrara Herbal establishes

The manuscript securely establishes several parts of the world we are building.

1. Arabic-derived pharmacology was deeply installed in northern Italian medicine

Serapion’s work had entered Latin medical circulation and could be translated again into a Paduan vernacular. (ResearchGate)

2. Medical knowledge moved beyond the University without leaving learned culture

The Carrara Herbal brought an established pharmacological text into a luxury court manuscript while retaining its connection to Paduan medical learning.

3. Vernacular language could carry complex medical knowledge

The local language was not confined to casual household remedies. It could support an extensive, prestigious pharmacological work commissioned by a ruling prince. (British Library)

4. Images and medical prose could be engineered as one system

Unlike Masson’s largely separated surviving layers, Carrara preserves substantial verbal and visual programmes together.

5. A medical book could perform political work

The manuscript linked Carrara patronage to learning, bodily health and the ruler’s representation as protector of the city. (ResearchGate)

6. The visual system remained transferable

The later Roccabonella Herbal demonstrates that Carrara imagery could be copied and adapted after the original court environment had disappeared. (PubMed Central (PMC))

What it does not establish

The Carrara Herbal does not by itself prove:

• that Francesco Novello personally practised medicine;
• that the manuscript was routinely used at a patient’s bedside;
• that an apothecary consulted this exact copy;
• that every illustration was drawn directly from nature;
• that the book contained every step necessary to execute a remedy;
• that its later custody can be reconstructed simply from the fall of Padua;
• that all Paduan medical practice followed Serapion uniformly;
• that vernacular translation made the book broadly accessible to ordinary citizens.

These edges must remain open.

The manuscript is powerful enough without forcing it to perform unsupported roles.

The third layer of the world

Our growing architecture now has three major regions.

Morgan M.873
The medical input universe:
what matter can be collected, extracted or manufactured?
Masson 116
The transferable visual corpus:
how can medical objects remain visible and copyable?
Carrara Herbal
The pharmacological meaning layer:
what are these substances believed to do,
and how can that knowledge be installed in Padua?

Together they take us much further towards a working medical world.

[
\text{source}
\rightarrow
\text{substance}
\rightarrow
\text{image and name}
\rightarrow
\text{quality and action}
\rightarrow
\text{selection}
\rightarrow
\text{preparation}
\rightarrow
\text{treatment}
]

The Carrara Herbal occupies the region of quality and action.

The later stages remain distributed.

A city translating the world into itself

The Carrara Herbal began with knowledge that had travelled across languages, regions and institutions.

Its substances came from plants, animals and stones.

Its pharmacology came through Arabic and Latin traditions.

Its final language belonged to Padua.

Its material form belonged to a courtly manuscript workshop.

Its political meaning belonged to the last Carrara regime.

Its images later travelled beyond that regime.

The complete transformation is therefore:

Mediterranean medicine
→ Italian university knowledge
→ Paduan language
→ Carrara political identity
→ illustrated manuscript
→ later visual transmission

The Carrara Herbal is not merely a container of old remedies.

It is the record of a city installing the medical world into its own language and presenting that act as evidence of civilisation.

Morgan showed that medicine required the world to supply its materials.

The Carrara Herbal shows that a city must then translate those materials into meaning.

That is the next layer.

What the Carrara Herbal now lets us resolve

The Carrara Herbal does more than add another manuscript to the medical world reconstructed in this series.

It gives us a high-resolution control.

Because its historical host, pharmacological ancestry, language, commissioner, substantial text and visual programme are comparatively well preserved, it allows us to ask a more exact question:

What does an organised medieval medical knowledge system look like before its surrounding world, labels, page relations and practical operators become difficult to recover?

This matters because many surviving manuscripts preserve only part of their original system.

Some retain images but lose explanatory text.

Some retain names but not practical context.

Some preserve page organisation while the meaning of their visual divisions becomes uncertain.

Some survive after their workshops, courts, readers and operating environments have disappeared.

The Carrara Herbal shows what becomes visible when many of those layers remain joined.

It can therefore help us identify what has been lost elsewhere without claiming that another manuscript must be Carrara, descend from Carrara or perform the same function.

The governing firewall is:

[
\text{structural comparison}
\neq
\text{identity claim}
]

Carrara is not the answer key to every difficult medical manuscript.

It is a resolution instrument.

From the complete entry to the hidden architecture

The Carrara Herbal presents a comparatively integrated medical entry.

At minimum, the reader can encounter:

[
\text{identified substance}
+
\text{illustration}
+
\text{extended pharmacological text}
+
\text{entry boundary}
]

The text can carry inherited names, qualities, actions, bodily associations and possible uses.

The image can stabilise the substance as a visible object.

The page can keep the two channels near one another.

The manuscript’s larger organisation can preserve the entry inside an inherited pharmacological sequence.

This means that a medical manuscript is not merely:

[
\text{picture}
+
\text{words}
]

It is a layered record:

[
\text{field}
+
\text{partition}
+
\text{object}
+
\text{address}
+
\text{relation}
+
\text{text}
]

Carrara makes these layers easier to see because the pharmacological prose remains substantial.

When those layers are damaged, abbreviated or separated in another manuscript, the first task should not be to guess the plant or translate an isolated word.

The first task should be to recover the record architecture.

The manuscript page is a hierarchy

The Carrara Herbal teaches us to distinguish several levels that can otherwise be collapsed into one.

Object level

A depicted substance is made locally recognisable.

Label or name level

A compact textual form can identify or address that substance.

Entry level

The object and its text belong to one bounded record.

Chapter or category level

Several entries may belong to a larger inherited pharmacological division.

Manuscript level

The chapter sequence forms a complete knowledge object.

Institutional level

The manuscript is hosted by translators, artists, patrons, medical readers and the Paduan learned environment.

Civilisational level

Arabic-derived pharmacology is translated, re-hosted and installed inside another language and political world.

The hierarchy is therefore:

[
\text{substance}
\rightarrow
\text{entry}
\rightarrow
\text{category}
\rightarrow
\text{manuscript}
\rightarrow
\text{institution}
\rightarrow
\text{city}
\rightarrow
\text{transmission world}
]

A page-level mark should not automatically be assigned a manuscript-level meaning.

An illustration should not automatically be treated as a complete remedy.

A commissioner should not be treated as the daily medical operator.

A visual resemblance should not automatically become textual or functional identity.

Resolution depends upon keeping the levels apart.

The two textual scales

The deeper manuscript analysis suggests that medical pages may operate with at least two textual scales.

Item-level text

A short form may attach locally to one illustrated substance or component.

Its possible roles include:

• name;
• index form;
• identifier;
• abbreviated heading;
• local descriptor;
• or another compact address.

Record-level text

A longer prose unit may carry:

• qualities;
• actions;
• distinctions;
• preparation information;
• inherited authority;
• commentary;
• or the relation binding several items together.

Carrara demonstrates what happens when item identity and extended pharmacological meaning remain strongly connected.

Other manuscript architectures may separate them.

The resulting possibilities include:

[
\text{image}
+
\text{short label}
]

[
\text{image}
+
\text{short label}
+
\text{extended prose}
]

[
\text{several images}
+
\text{group anchor}
+
\text{one shared paragraph}
]

[
\text{visual corpus}
+
\text{missing or unfinished prose layer}
]

These are not necessarily different subjects.

They may be different assemblies of the same broad manuscript components.

A medical page can group before it explains

One of the most important results from the branch is that page organisation can carry information before any word is decoded.

A manuscript can communicate:

[
\text{these objects belong together}
]

through:

• proximity;
• repeated rows;
• shared paragraph fields;
• larger group-level images;
• headings;
• labels;
• blank-space boundaries;
• or recurring page positions.

The page itself may perform part of the grammar.

This means that a medical manuscript may possess a recoverable structural statement such as:

[
A_j
\rightarrow
{x_{j1},x_{j2},\ldots,x_{jn}}
]

where:

• (A_j) is a group-level anchor;
• (x_{ji}) are individually addressable members;
• and the arrow means only that the members belong to one local record.

At first, we should not translate the arrow as:

• “combine”;
• “store inside”;
• “use for”;
• “substitute with”;
• or “prepare as.”

The safest initial reading is:

These members are grouped under this anchor.

That is already a structural decode.

It recovers hierarchy without inventing semantics.

Grouping is not yet containment

A container-shaped image beside medical components naturally invites a literal interpretation.

It may indeed represent a vessel.

But the page can use a vessel-like form in several ways:

• literal storage container;
• preparation-state marker;
• category emblem;
• chapter heading;
• batch identifier;
• visual divider;
• or relation marker.

The secure operation may be:

[
GROUP(x_1,x_2,\ldots,x_n)
]

before it is:

[
CONTAIN(x_1,x_2,\ldots,x_n)
]

Carrara helps discipline this distinction.

Its elaborate images are visibly medical and courtly, but even Carrara does not allow every visible relationship to be converted directly into bedside execution.

The page can preserve pharmacological knowledge without depicting the complete treatment process.

In the same way, another manuscript may preserve a category architecture without depicting literal physical containment.

The possible relations inside a medical batch

Once grouping has been demonstrated, several relations remain possible.

AND

[
x_1 \land x_2 \land x_3
]

The members are combined in one preparation.

OR

[
x_1 \lor x_2 \lor x_3
]

The members are alternatives, substitutes or conditional choices.

IS-A

[
x_i \in C
]

The members belong to one category.

STATE

[
STATE(x_1,x_2,\ldots,x_n)
]

The members share one preparation, preservation or material condition.

SOURCE

[
B_j = SOURCEUNIT_j
]

The group preserves an inherited chapter, list or source division.

LIST

[

[x_1,x_2,\ldots,x_n]

]

The members are simply enumerated.

Carrara makes several of these historically plausible because its underlying pharmacology already belonged to a structured tradition of simples, qualities, actions and transmitted textual divisions.

But historical plausibility cannot choose the operator by itself.

The manuscript under examination must supply the internal evidence.

How the operators can be distinguished

Each possible relation predicts a different internal pattern.

A combined preparation should tend to show

• diverse members;
• strong item-to-prose dependency;
• possible member order;
• repeated preparation structure;
• or common ingredients recurring in several groups.

A substitute or alternative class should tend to show

• parallel individually labelled members;
• structured variation;
• contrastive or repeated prose patterns;
• and possible reuse of one member under several conditions.

A category should tend to show

• strong group-heading or anchor relationships;
• individually distinct member labels;
• and prose operating at the class level.

A shared preparation state should tend to show

• similar truncation, bundling or represented parts;
• recurring anchor forms;
• and strong anchor-to-prose relationships.

An inherited source unit should tend to show

• stable paragraph and entry boundaries;
• variable visual similarity among members;
• and strong textual continuity even when the member set is heterogeneous.

A merely spatial list should tend to show

• weak member cohesion;
• weak label-to-prose attraction;
• interchangeable group anchors;
• and no improvement over shuffled arrangements.

These predictions allow function to be tested rather than declared.

Three kinds of cohesion

Every proposed medical group can be measured through three independent channels.

Visual cohesion

Do the members resemble one another more than matched members elsewhere on the same page?

This should be tested through:

• branch structure;
• terminal form;
• junction geometry;
• repeated internal markings;
• asymmetry;
• and rare anomalies.

Broad resemblance such as “both are roots” or “both are three-lobed” is too weak.

Item–text cohesion

Do the short labels associated with the members fit their own prose unit better than neighbouring prose units?

This does not require exact word repetition.

It may involve a recurrent morphological family or a stable conversion between display form and running-text form.

Anchor–text cohesion

Does the group-level label or image fit the opening and framework of its own paragraph better than those of neighbouring groups?

These three measures produce a diagnostic triangle:

[
T(B)=[V,I,A]
]

where:

• (V) is visual cohesion;
• (I) is item–text cohesion;
• (A) is anchor–text cohesion.

Different patterns imply different record types.

For example:

[
V\text{ low},\ I\text{ high},\ A\text{ medium}
]

would be compatible with a diverse ingredient collection.

[
V\text{ high},\ I\text{ low},\ A\text{ high}
]

would be compatible with a visually defined category explained at group level.

[
V\text{ low},\ I\text{ low},\ A\text{ high}
]

would be compatible with a preparation class, category heading or inherited source unit.

This lets the page reveal where its organising information resides.

Rare structure matters more than broad resemblance

The branch also establishes a necessary visual discipline.

A proposed correspondence should not be promoted because two drawings share:

• a bulb;
• a fork;
• fibres;
• three lobes;
• or a broadly plant-like outline.

Those forms recur naturally inside a restricted visual vocabulary.

Higher-value evidence includes:

• off-centre enclosed regions;
• unequal bilateral division histories;
• split-and-rejoin paths;
• compound collars or boundaries;
• fixed-count bundles;
• selective internal markings;
• displaced attachments;
• interrupted symmetry;
• nested terminals;
• and repeated unusual asymmetry.

The correct family unit is:

[
\text{broad class}
+
\text{rare anomaly}
+
\text{supporting topology}
]

A rare anomaly must also recur.

A unique feature may be a drawing accident.

A repeated feature confined to one folio may be a local artistic habit.

A feature recurring predictively across independent manuscript units becomes evidence of a portable visual family.

Resemblance is not correspondence

The complete promotion ladder is:

[
\text{resemblance}
\rightarrow
\text{candidate correspondence}
\rightarrow
\text{supported correspondence}
\rightarrow
\text{recurrent class}
\rightarrow
\text{dependency}
\rightarrow
\text{predictive dependency}
]

A visual pair should move upward only when:

1. its structural features were defined before the match was selected;
2. it outperforms hard false alternatives;
3. the same transformation recurs elsewhere;
4. text or codicology supplies independent support;
5. and the rule predicts a hidden example.

This is how Carrara should be used in the wider cloud.

Not as:

This other manuscript looks medical, therefore it is Carrara-like.

But as:

Carrara shows which layers a coordinated medical manuscript can contain. We can now test which of those layers survive in the other manuscript.

The page must be allowed to be incomplete

Masson 116 already demonstrated that a planned manuscript can preserve one production layer while another remains absent.

Carrara demonstrates a more complete convergence of image and substantial text.

Together, they establish a range:

[
\text{visual corpus with missing extended text}
\longleftrightarrow
\text{coordinated visual–pharmacological manuscript}
]

A difficult manuscript may fall somewhere between them.

Its page architecture may remain recoverable even when:

• some labels were never completed;
• explanatory prose was lost;
• a planned layer was abandoned;
• images were copied from another source;
• text and image were assembled at different stages;
• or later damage removed one channel.

Missing information should therefore be marked:

[
\text{unobservable}
]

rather than automatically:

[
\text{semantically absent}
]

This prevents unfinished production from being misread as intentional silence.

The likely production layers

A medical manuscript can be assembled through separable stages:

[
\text{page planning}
\rightarrow
\text{ruling}
\rightarrow
\text{image allocation}
\rightarrow
\text{image production}
\rightarrow
\text{prose}
\rightarrow
\text{group labels}
\rightarrow
\text{item labels}
\rightarrow
\text{colour}
\rightarrow
\text{binding}
]

The exact order may differ by manuscript.

The important principle is modularity.

The survival of one layer does not prove that every other layer was completed.

The absence of one layer does not prove that the remaining page was meaningless.

A component can survive, travel and acquire a new use after its original assembly has broken.

Carrara’s later visual transmission into the Roccabonella tradition demonstrates this modular portability. Its images could continue travelling after the political host that commissioned them had disappeared.

Labels may change when they enter prose

A short label attached to an image and a related form in running prose need not be identical.

The branch therefore separates:

[
x
]

as a possible display or label form from:

[
T(x)
]

as a possible prose-integrated form.

One candidate transformation is:

[
x
\rightarrow
q+x
]

But this should not yet be translated as “use,” “with,” “of” or any other word.

Several possibilities remain:

• q may be a reference marker;
• q may integrate a label-like base into ordinary prose;
• q may be one member of a wider prefix system;
• another prefix may perform the same role;
• the relevant change may instead be a suffix;
• or the apparent relation may arise automatically from the script’s word templates.

The correct question is not:

Can a label and a prefixed form both be found?

It is:

Does the transformed form occur preferentially in the correct record, outperform matched non-label bases and competing transformations, survive alternative transcriptions and predict unseen examples?

Until then:

[
x\rightarrow q+x
]

is a candidate structural correspondence, not a lexical decode.

The hard null must come first

Every apparent manuscript relationship must compete against the possibility that it arose automatically.

For visual matches, controls should preserve:

• broad outline;
• component class;
• branch count;
• complexity;
• and drawing environment.

For textual matches, controls should preserve:

• word length;
• prefix and suffix template;
• frequency;
• paragraph position;
• language state;
• scribal hand;
• and transcription uncertainty.

For page relationships, controls should shuffle:

• labels among items;
• paragraphs among groups;
• anchors among member fields;
• and visual components among matched positions.

The manuscript’s observed arrangement should outperform those alternatives.

The strongest test is predictive:

1. learn the rule from some records;
2. hide another page or bifolio;
3. predict the correspondence, boundary or textual relation;
4. reveal the original arrangement;
5. record success and failure without changing the rule.

This converts manuscript interpretation into a falsifiable experiment.

The minimal medical-page grammar

The branch allows us to write a neutral grammar that can be applied without identifying the objects.

Let:

• (A) be a group-level visual anchor;
• (a) its optional short label;
• (x) an illustrated member;
• (l) its optional item label;
• (p) an associated prose unit.

Then:

[
PAGE
\rightarrow
BATCH^{+}
]

[
BATCH
\rightarrow
ANCHOR
+
MEMBER_FIELD
+
PROSE
]

[
ANCHOR
\rightarrow
A[a]
]

[
MEMBER_FIELD
\rightarrow
ROW^{+}
]

[
ROW
\rightarrow
ITEM^{+}
]

[
ITEM
\rightarrow
x[l]
]

This does not say that the anchor is a jar.

It does not say that the members are ingredients.

It does not say that the prose is a recipe.

It says only:

The page contains repeated group-level records. Each record contains a prominent anchor, one or more individually addressable illustrated members and associated running text.

The operations recovered at this level are:

[
SEGMENT
]

[
GROUP
]

[
ANNOTATE
]

These are genuine document operations even before semantics are known.

What Carrara contributes to this grammar

The Carrara Herbal occupies a richer position in the same analytical space.

Its entries show that a medical record can coordinate:

[
\text{visible substance}
+
\text{name}
+
\text{pharmacological prose}
+
\text{inherited textual authority}
+
\text{local language}
]

This helps us understand what a shorter, divided or damaged record may be missing.

Carrara supplies several controlled possibilities:

A picture may support identity without supplying use

A name may stabilise retrieval without supplying recognition

Extended prose may carry qualities and actions without supplying the complete treatment runtime

A manuscript may preserve pharmacology without being the object used to compound every remedy

A vernacular translation may widen access without becoming popular household medicine

A court commission may host medical knowledge without making the commissioner its practitioner

A later copy may preserve the image while changing the book’s ownership, sequence or use

These distinctions become the firewalls for analysing less explicit material.

Why Carrara belongs inside the wider manuscript cloud

Carrara should remain inside the research cloud because it provides a high-resolution example of successful knowledge re-hosting.

Its path is:

[
\text{Arabic-derived pharmacology}
\rightarrow
\text{Latin learned circulation}
\rightarrow
\text{Paduan vernacular}
\rightarrow
\text{court manuscript}
\rightarrow
\text{later visual descendants}
]

The important transferable capabilities are:

• substance-to-property mapping;
• image–name stabilisation;
• translation across knowledge environments;
• separation of patron, translator, painter and operator;
• modular manuscript construction;
• visual transmission beyond the original political host;
• and preservation of pharmacological meaning without preservation of the complete practical runtime.

Carrara therefore helps answer a narrower question than:

Is another manuscript the same kind of book?

It helps answer:

Which components of a medieval medical knowledge system are present, absent, separated, compressed or re-hosted in the other book?

That is a much safer and more useful comparison.

The resolution packet Carrara now supplies

The manuscript can now be represented across several coordinates.

Object coordinate

OBJECT:
Carrara Herbal / Egerton MS 2020
TYPE:
illustrated vernacular pharmacological manuscript
NOT:
complete bedside treatment runtime
ordinary field guide
proof of universal Paduan medical practice

Representation coordinate

living or traded substance
→ inherited name
→ Latin pharmacological term
→ Paduan expression
→ painted image
→ manuscript entry
→ later copied image

Capability coordinate

recognise
name
retrieve
classify
interpret qualities
associate actions
translate
teach
copy
preserve

Each capability should be marked:

• demonstrated;
• supported;
• possible;
• absent;
• or unknown.

Human-role coordinate

patron funds
translator re-hosts language
scribe installs text
artist makes the substance visible
medical interpreter preserves pharmacological coherence
physician connects the entry to diagnosis
apothecary connects the name to physical stock
reader retrieves and compares

Transmission coordinate

text
image
name
entry order
page architecture
medical authority
courtly meaning

These components can travel together or separately.

Failure-and-survival coordinate

Carrara political host ends
manuscript survives
ownership changes
original readership disperses
visual components continue travelling
later users reinterpret the object

This is the deeper value of the Carrara Herbal.

It lets one manuscript be read simultaneously as:

• a medical text;
• a visual system;
• a translation event;
• a court object;
• a production network;
• a transmission source;
• and a survivor of institutional collapse.

What Carrara can resolve—and what it cannot

Carrara can help us recognise:

• that text and image may form separate but coordinated channels;
• that page hierarchy may be meaningful before its words are translated;
• that labels may operate at different resolutions;
• that one manuscript can combine inherited and locally produced components;
• that images can travel without preserving the complete original function;
• that knowledge can survive the political host that assembled it;
• and that medical capability remains distributed beyond the book.

Carrara cannot by itself prove:

• that another manuscript was made in Padua;
• that another script encodes Paduan, Latin or Arabic;
• that another plant-like image is medicinal;
• that a container-shaped drawing is a literal apothecary vessel;
• that grouped components are combined ingredients;
• that a visual resemblance establishes direct copying;
• that an incomplete manuscript once contained Carrara-like prose;
• or that a repeated textual form has a particular translation.

The control manuscript narrows possibilities.

It does not remove the need for internal proof.

The deeper Padua stack

The Carrara Herbal now occupies one layer in a complete vertical Atlas.

[

Atlas 60 expands horizontally across many worlds.

The Padua manuscript stack moves vertically into one world.

Together they create:

[
\boxed{
\text{world breadth}
\times
\text{local depth}
\times
\text{typed transmission}
}
]

The Carrara Herbal is therefore not only a subject inside the Atlas.

It is one of the instruments that increases the Atlas’s resolution.

The final methodological result

The Carrara Herbal shows us what an unusually successful medical assembly can look like:

[
\text{substance}
+
\text{image}
+
\text{name}
+
\text{pharmacology}
+
\text{translation}
+
\text{institution}
+
\text{patronage}
]

The wider manuscript investigation teaches us how to proceed when those elements are no longer securely joined.

The sequence should be:

[
\text{recover the field}
]

[
\rightarrow
]

[
\text{recover its partitions}
]

[
\rightarrow
]

[
\text{identify group-level and item-level nodes}
]

[
\rightarrow
]

[
\text{test local label attachment}
]

[
\rightarrow
]

[
\text{test image–text dependency}
]

[
\rightarrow
]

[
\text{compare competing relation operators}
]

[
\rightarrow
]

[
\text{challenge every result with matched nulls}
]

[
\rightarrow
]

[
\text{require prediction before semantic promotion}
]

Only after that should historical identity or medical function be proposed.

The governing laws are:

[
\boxed{
\text{resemblance is not correspondence}
}
]

[
\boxed{
\text{correspondence is not dependency}
}
]

[
\boxed{
\text{grouping is not containment}
}
]

[
\boxed{
\text{association is more secure than direction}
}
]

[
\boxed{
\text{historical plausibility is not internal proof}
}
]

Carrara does not solve another manuscript by resemblance.

It teaches us what must be recovered before another manuscript can be understood.

That is its new place inside the cloud:

The Carrara Herbal is both a completed Paduan pharmacological world and a control instrument for measuring how much of a medical knowledge system survives when image, label, prose, operator, institution and practical runtime begin to separate.
