Entity: standard reference for European astronomers before Copernicus
Triple: [Alfonsine Tables, historicalSignificance, standard reference for European astronomers before Copernicus]

The Alfonsine Tables were a 13th-century set of astronomical tables, commissioned by King Alfonso X of Castile, that provided planetary positions and became the principal computational tool for European astronomers until the Copernican revolution.
