In the Middle Ages, some Arabic authors were familiar with and extended Archimedes' work on balances and centre of gravity; in the Latin West, however, these ideas were virtually unknown except for a handful of limited cases.[11][12] It is only in the Renaissance that the results found in On the Equilibrium of Planes began to spread widely. Archimedes' mathematical approach to physics, especially, became a model for subsequent scientists such as Guidobaldo del Monte, Bernardino Baldi, Simon Stevin, and Galileo Galilei.[13][14]
