The son of Francesco Arrighetti and Fiammetta Ginori, as a young man he was a private student of Galileo’s, together with his cousin Andrea Arrighetti. Around 1614, Arrighetti assisted Galileo in replying to an attack by Giorgio Coresio on his views of the behaviour of bodies in water. Arrighetti maintained a close interest in Galileo’s experiments in physics and his mathematical work (notably on the flow of water in both straight and twisting channels). It was also Arrighetti who brought Galileo news from Benedetto Castelli about the dispute between Castelli and Cosimo Boscaglia, that prompted Galileo to write his Letter to Benedetto Castelli. A number of Galileo’s notes, sketches and drawings on various topics, including motion, were recorded or copied by Arrighetti.
