On July 4, 1483 German printer Erhard Ratdolt, working in Venice, published Tabulae Alphonsinae or the Alphonsine Tables, a compilation of astronomical data tabulating the positions and movements of the planets.
The Alphonsine Tables were among the first mathematical tables printed. The tables were computed at Toledo, Spain, from 1262 to 1272 by about 50 astronomers (human computers) assembled for the purpose by King Alfonso X of Castile and León, known as el Sabio, "the learned." They were a revision and improvement of the Tables of the Cordoban mathematician/astronomer Abū Ishāq Ibrāhīm al-Zarqālī, retaining the Ptolemaic system for explaining celestial motion. The original Spanish version was lost, and the tables became known through Latin translation.
