Alfonsine Tables

c. 1252–1270 · 13th century

The Alfonsine Tables were astronomical tables for calculating the positions of the Sun, Moon and planets, compiled in Toledo under Alfonso X of Castile by the Jewish scholars Isaac ibn Sid and Judah ben Moses. Spread in Latin versions from Paris and first printed in 1483, they remained the standard tables in Europe until the Copernican Prutenic Tables of 1551.
