RENIERI, Vincenzio (1606-1647). Tabulae Mediceae secundorum mobilium universales quibus per unicum prosthaphaereseon orbis Canonem Planetarum calculus exhibetur. Florence: Amador Massi and Lorenzo Landi, 1639.

First edition of Renieri’s "Medicean" planetary tables, dedicated Ferdinand II de’ Medici, Grand Duke of Tuscany. The author, Renieri, was a friend and disciple of Galileo. He worked extensively with Vincenzo Viviani to continue Galileo's observations of Jupiter's moons, but this is his only lifetime publication and unrelated to that project, which had the ultimate goal of perfecting a method for determining longitude at sea. The present work is an update to Kepler's Rudolphine Tables, offering a new method for calculating longitudes. Due to his premature death, the manuscript of his Jupiter observations was never printed and eventually lost. Carli and Favaro 174; Drake, Galileo at Work; Riccardi I.2 348 n 2.
