Vatican Manuscripts Added Week 5 of 2026

On Friday of this week eighteen manuscripts were digitized, the only day of activity. Of those, sixteen were from Ott.lat, and one each from Chig and Vat.lat.

At the right is f.121r from Ott.lat.2150, a glossed copy of Porphyry's Isagoge dated to the 13th C. This text is roughly an introduction to Aristotle's Categories and formed the basic textbook on logic for much of the middle ages. This page begins "De sophisticis aute[m]" which is the start of Aristotle's "Sophistici Elenchi"

At the bottom is a nearly incomprehensible line of text from f.8r of Ott.lat.2121, a 16th C collection of medical excerpts. This page begins a section on the causes of fevers
