La ciroxia vulgarmente fata.

Saliceto was Professor of Surgery at Bologna about 1268; his treatise on surgery, written about 1275, was the leading work on the subject in the 13th century. William broke with tradition by claiming that pus formation was bad for wounds and for the patient. His treatise on surgery promoted the use of a surgical knife over cauterizing. 

This Italian translation is the first medical book printed in Italian, and probably the first work on surgery ever printed; the original Latin text was printed two years after the Italian edition. Book IV contains the first known treatise on surgical anatomy. English translation by Leonard D. Rosenman as The Surgery of William of Saliceto (2002).  ISTC no. is00027000.
