Voynich and Padua | Which Euganean Bath? The Local-Parameter Test

“The Voynich figures are bathing.”

Even if that were true, Padua would still not follow.

Medieval Europe had many bathing traditions.

The Padua hypothesis only gains serious geographic value when the question becomes much narrower:

Which Euganean bath?

Abano is not Monteortone.

Montegrotto is not Sant’Elena.

San Pietro Montagnon is not a generic pool.

The local-parameter test asks whether a Voynich page preserves enough specific structure to distinguish one therapeutic landscape from another.

Quick Read

University of Padua’s MEDICAMENTA project identifies a network of Euganean thermal sites discussed by medical authors.
Named sites include Abano, Monteortone, San Bartolomeo, San Pietro Montagnon, Montegrotto and Sant’Elena at Battaglia Terme.
The same source also describes the Domus novae, linked to salt-production experiments associated with Iacopo Dondi.
Bartolomeo da Montagnana and Michele Savonarola are among the Paduan medical authors who described the thermal region.
This creates geographically specific therapeutic nodes rather than one vague “Paduan bath” idea.
A Voynich connection becomes meaningful only if page structure predicts a local spring, treatment sequence, mineral use, bathing mode or site-specific feature.
Generic water, pools, tubes or naked figures remain low-value for localisation.

The Word “Abano” Has Been Doing Too Much Work

Abano is famous.

Pietro d’Abano is famous.

Voynich has water-like imagery.

The mind connects them immediately.

But the Euganean thermal system was distributed across several sites with different physical and historical identities.

That distribution is useful because it gives us internal controls inside the Padua hypothesis itself.

Abano Is One Node

Abano was among the major thermal sites described in the Paduan medical tradition.

Its importance is real.

But a hypothesis should not stop at fame.

If Voynich truly encoded Abano, we would want structure that differentiates Abano from neighbouring thermal sites rather than simply “people in water”.

Monteortone Creates a Separate Site Test

MEDICAMENTA identifies Monte Ortone among the baths described in the regional medical corpus.

A site-specific model would ask whether its therapeutic use, water characteristics, access, treatment practices or associated textual descriptions differ enough to generate a unique manuscript signature.

If no such discriminator exists, Monteortone cannot be separated from Abano in Voynich terms.

San Pietro Montagnon Gives Us Another Coordinate

The thermal tradition also names Sanctus Petrus, identified with San Pietro Montagnon.

This matters because the region is not represented by one undifferentiated hot-water environment.

A serious local test would build a site matrix:

water source;
temperature;
mineral properties;
bathing method;
drinking use;
conditions treated;
seasonality;
infrastructure;
medical author describing it.

Only after that can a Voynich diagram be compared meaningfully.

Montegrotto Is Not Just Another Name

MEDICAMENTA explains Montegrotto through the historical form Mons Aegrotorum, the “mount of the sick”.

The phrase itself captures the therapeutic identity of the landscape.

If Voynich ever yields a readable local place-name or phrase that corresponds to such a tradition, the evidential value would be much greater than image resemblance.

But until then, the name belongs to the control corpus, not the solution.

Sant’Elena Gives Us a Natural Cave

The baths of Sancta Helena are identified by the University of Padua with a natural thermal cave at Battaglia Terme.

This is exactly the kind of specific physical feature that a local-parameter test wants.

A cave-based thermal environment should generate different spatial and practical descriptions from an open pool or constructed bathing facility.

If Voynich’s spatial grammar could be shown to encode a cave-like therapeutic site, Sant’Elena would become more relevant.

If not, the analogy remains weak.

The Domus Novae Add a Technical Layer

MEDICAMENTA also describes the Domus novae, constructed as salt-production facilities following experiments associated with Iacopo Dondi.

This is one of the most interesting intersections in the entire regional model.

The same Paduan technical world that includes astronomical computation also interacts with thermal resources materially.

That creates a local network among:

thermal water;
medicine;
salt and mineral extraction;
technical experimentation;
Dondi-family knowledge.

This is a much richer hypothesis than “Voynich shows baths”.

But the Domus Novae Do Not Explain Voynich Tubes

The temptation is immediate.

Technical facilities.

Thermal water.

Salt production.

Voynich tubes.

But we still need operational correspondence.

A genuine relationship would require:

flow logic;
processing stages;
repeated apparatus classes;
material transfer;
textual labels that align with operations.

Without those, the Domus novae are a fascinating control and nothing more.

Montagnana Gives the Local Medical Layer

Bartolomeo da Montagnana matters because he belongs to practical medicine in Padua during the Voynich window and wrote on the local baths.

That means the thermal landscape is not merely a tourist environment.

It enters learned and practical medical discourse.

The stronger comparison is therefore not image to bath.

It is therapeutic protocol to therapeutic protocol.

Savonarola Gives the Comparative Bath Catalogue

Michele Savonarola later wrote extensively on thermal waters and preserved descriptions of the Paduan thermal region alongside other Italian sites.

This is useful because it gives us internal and external comparisons.

If a treatment is common across many Italian baths, it has little localising power.

If one procedure or site description is unusually Euganean, its value increases.

What a Site-Specific Voynich Match Would Need

A thermal interpretation that first passes basic hydraulic and therapeutic tests.
A repeated procedure rather than one visual resemblance.
A feature distinguishing one Euganean site from generic European baths.
Independent textual, geographic or technical confirmation.
A chronology compatible with the relevant medical source.

Possible Local Parameters

The most promising variables are not the people in the pools.

specific spring or cave geometry;
named therapeutic sequence;
mineral or salt-processing operation;
site-specific water temperature or use;
regional place-name;
repeated relation between bathing and particular medical conditions.

These are the thermal equivalent of the Padua meridian.

They turn landscape into coordinate.

The Matched-Control Requirement

Every proposed Euganean match must be tested against other bath traditions.

German, Austrian, French, Tuscan and other Italian thermal sites belong in the denominator.

If the same feature is common elsewhere, it cannot localise Padua.

the question is never “can Padua explain this?” It is “does Padua explain this specific feature better than matched thermal alternatives?”

What Would Strengthen the Euganean Connection?

a local place-name inside a robust reading;
a site-specific therapeutic protocol;
diagram geometry matching a distinctive installation;
a Dondi-related thermal-technical operation;
multiple independent local correspondences.

What Would Weaken It?

Voynich tubes failing hydraulic logic;
human figures behaving as category tokens rather than patients;
features proving common across European bathing manuscripts;
no local Paduan/Euganean parameter emerging;
a stronger non-thermal interpretation of the same pages.

The Final Idea

“Baths near Padua” is no longer a useful endpoint.

If the Euganean hypothesis is real, the manuscript should eventually tell us not only that water matters, but which local therapeutic system matters and why. The next valid question is not “is this Abano?” It is “what evidence distinguishes Abano from every other bath?”
