Shovel of Ascanio Piccolomini in the Accademia della Crusca

Ascanio was a mathematics pupil of Bonaventura Cavalieri.[2] He hosted Galileo in Siena.[3] According to Dava Sobel, Galileo's ability "to rise from the ashes of his condemnation by the Inquisition" and complete perhaps his most influential book, the Two New Sciences, was "due in large measure to Piccolomini's solicitous kindness".[4]

He was the younger brother of commander Ottavio Piccolomini.

While bishop, he was the principal co-consecrator of Carlo Fabrizio Giustiniani, Bishop of Accia and Mariana (1656).[1]
