Marco Fabio Calvo’s Latin Hippocratic Opera is printed at Rome
In 1525 a Latin Opera of Hippocrates associated with Marco Fabio Calvo was printed at Rome, putting humoral treatises into a language Western faculties already taught. In the causal graph this event strengthens Infectious-Disease Transmission, a driver that weakens Life expectancy at birth — a worsening welfare path.

Read the full account
In 1525 a Latin Opera of Hippocrates associated with Marco Fabio Calvo was printed at Rome, putting humoral treatises into a language Western faculties already taught. The book is a completed printing. It is not a Greek critical text and not a clinical trial. Latin recipes travelled farther than Greek manuscripts had.
Context
Renaissance physicians read Latin more easily than Greek. A Latin Hippocratic set therefore mattered more for bedside humoral practice than the 1526 Aldine Greek did. Bloodletting, purging, and climatic regimen could now be cited from a printed ‘prince of physicians’. Later cholera and yellow-fever depletions used that authority.
Hippocrates of Cos is not the sole author of every Greek medical treatise later copied under his name, and he is not the signer of every later oath or code that quoted him. Shared work with unnamed Coan practitioners, Alexandrian compilers, Galen, Latin printers, medical faculties, and twentieth-century medical associations does not erase the Cos identity Plato used, and it does not make a fifth-century physician the author of the 1948 Declaration of Geneva.
Why it matters
Worsening path onto later infectious-disease handling via humoral recipes. Medium confidence on the lag into 18th–19th century practice.
Print can spread observation and also spread depletion. The Aldine Greek is the access gain. This Latin set is the recipe-book risk.
A printed corpus does not vaccinate a child. An oath does not staff a clinic.

The heading is Hippocratic. The Latin prescriptions and the print run are Calvo’s and the Roman press’s.

What the sources establish
NLM and Britannica independently describe Latin reception of the corpus. Surviving 1525 copies are catalogued in research libraries. Wikipedia is not used as the causal source.
Established: a Latin Hippocratic Opera was printed at Rome in 1525. Not established: that Calvo caused a specific epidemic death total, or that Hippocrates wrote every translated treatise.
The documentary trail can name an office, printer, code, trial, or treatise heading; it cannot name a complete Coan patient register. Confidence belongs on the impact path. Estimates of later harm from humoral treatment, where historians publish them, are attributed to those historians, not invented here.
A Cos vita, a medieval oath manuscript, a Venetian folio, and a twentieth-century medical-association code are different instruments even when they share a heading. Hippocrates’ contribution, where it exists, is the name and the later use of treatises grouped under that name, not a modern ministry signature. Sharing labour with printers, editors, prosecutors, or assemblies is not a reason to drop the row and not a reason to treat the row as a clinical trial. If a number of deaths, doses, or pupils is not in the official or independent record named above, it is not supplied here.
