Alfonsine tables

The Alfonsine Tables (Spanish: Tablas Alfonsíes, Latin: Tabulae Alphonsinae), sometimes spelled Alphonsine Tables, provided data for computing the position of the Sun, Moon and planets relative to the fixed stars.

The tables were named after Alfonso X of Castile, who sponsored their creation. They were compiled in Toledo, Spain, and contain astronomical data starting on June 1, 1252, the date of the coronation of the King.
