Vincentio Reinieri

Who was Vincentio Reinieri?

Vincentio Reinieri was an Italian mathematician and astronomer. He was a friend and disciple of Galileo Galilei.

Born at Genoa, he was a member of the Olivetan order. His order sent him to Rome in 1623. He met Galileo at Siena in 1633. Galileo had Reinieri update and attempt to improve his astronomical tables of the motions of Jupiter's moons, revising these tables for prediction of the positions of these satellites.

Reinieri's work led him to Arcetri, where he befriended Vincenzo Viviani. Reinieri enjoyed the same spirit of inquiry and love of debate as his mentor. On February 5, 1641, Reinieri wrote Galileo from Pisa: "Not infrequently I am in some battle with the Peripatetic gentlemen, particularly when I note that those fattest with ignorance least appreciate your worth, and I have just given the head of one of those a good scrubbing."

Reinieri became professor of mathematics at the University of Pisa on the death of Dino Peri. He also taught Greek there. His astronomical work consisted of adding new observations of Jupiter's moons to Galileo's. To some degree, Reinieri improved the Galilean tables on the motions of these satellites.
