She was forced into war by Mastino della Scala, lord of Padua, Vicenza, Treviso, Feltre and Belluno, as well as of Verona, who imposed a duty on the transport of Venetian goods.
Vittorino dei Rambaldoni da Feltre (1378-1446) was a famous educator and philosopher of his time.
The first great school of the Renaissance was that established by Vittorino da Feltre at Mantua, where he resided for the last twenty-two years of his life (1424-1446).
Raised to the see of Feltre in 1512, he went on another embassy to Maximilian in 1513, and was created cardinal priest of San Tommaso in Pavione, 27th of June 1517.
He learned Latin from Vittorino da Feltre, and made such rapid progress that in three years he was able to teach Latin literature and rhetoric. His reputation as a teacher and a translator of Aristotle was very great, and he was selected as secretary by Pope Nicholas V., an ardent Aristotelian.
