Giulio Cesare Casseri

Giulio Cesare Casseri, also written Giulio Casserio of Piacenza and in Latin Iulius Casserius Placentinus, was an Italian anatomist who lived from 1552 to 1616. Born in Piacenza, he moved to Padua as a young man and became an assistant to the anatomist Hieronymus Fabricius, and his teachers included Girolamo Mercuriale. He fell out with Fabricius, apparently because Fabricius resented the students' enthusiasm for his teaching. He is best known for the Tabulae anatomicae of 1627, with ninety seven copper engraved pictures, and for De vocis auditusque organis historia anatomica, printed in 1600 and 1601 in Ferrara. He was the first to describe the Circle of Willis.
