Book of Alfonsine Tables

The Alfonsine Tables is a medieval book containing astronomical tables prepared for King Alfonso the Wise. They contain observations made in Toledo's firmament from January 1st, 1263 to 1272 and record the movement of the respective celestial bodies on the ecliptic with precise positions. The aim of the tables was to share a schema of practical use to anticipate the position of the sun, moon, and the planets according to geocentrism.
