The Alfonsine tables (sometimes spelled Alphonsine tables) provided data for computing the position of the Sun, Moon and planets relative to the fixed stars. They are named for Alfonso X of Castile, upon whose order they were prepared in Toledo, Spain around 1252 to 1270. Alfonso X assembled a team of scholars, including both Jews and Moors, to produce new tables that updated the Tables of Toledo. The new tables were based on observations by Islamic astronomers and on earlier astronomical works preserved by Islamic scholars. The instructions for the Alfonsine tables were originally written in the Castilian Spanish, but a version in Castilian has not survived. What are now called Alfonsine tables seem to have originated in Paris around 1320 in Latin. They were calculated in that city by two Frenchmen, Pierre de Saint-Cloud and Jean de Murs, who retained the name of Alfonso X.
