Note 3 — Dedication.
Reading edition
Angelo Cato, born at Sopino, in the diocese of Benevento, was “a person of exemplary life, great learning, extreme modesty, and wonderful knowledge of mathematics.” In his youth, he entered the service of the princes of Anjou; but, being sent by them on a mission to the Duke of Burgundy, he transferred his allegiance to that prince, at whose court he began his life-long friendship with Commines. Cato was a skilful astrologer, and predicted to Charles the Bold that he would lose the battles of Granson and Morat. After the fulfilment of his predictions, he took leave of the duke, and was immediately taken into the service of Louis XI., who appointed him his physician and almoner, and made him Archbishop of Vienne in 1482.
