This is a print on demand publication. Berengario da Carpi obtained his doctorate in med. in Bologna in 1489. He was elected to the chair of surgery in 1502 & to that of med. in 1505. In 1508 during an outbreak of plague he was charged by the city gov’t. with combatting its ravages as chief health officer. In 1517 Berengario was called to Ancona, where Lorenzo dei Medici had been wounded, resulting in an occipital fracture & consequent shock trauma. His treatment is described in “De Fractura,” f. 25 b. The event represented a significant advance in Berengario’s professional experience, recorded in the “De Fractura Calvae sive Cranei,” which was inspired by the occurrence. He dedicated the work to this patient, Lorenzo, to whom Machiavelli had also dedicated “The Prince” in 1513. Illus.
