Galeno, Commento a Officina Medici (Un nuovo incipit per il III libro)

By the means of a reexamination of the manuscript tradition of the galenic commentary to Hippocrates' De Officina Medici, this paper proposes to reconsider the incipit of the third book of the commentary itself, as it is printed in modern editions since the princeps. A strong evidence supporting the author's hypothesis is given by the arabic compendium of Ali ibn Ridwan, written in the XIth century A.D., whose third section starts with the same sentence recognised here as the real incipit of the third book.
