The '''''Alfonsine tables''''' (also sometimes spelled '''''Alphonsine tables''''') were [[ephemeris|astronomical tables]] drawn up at [[Toledo, Spain|Toledo]] by order of [[Alfonso X]] around [[1252]] to 1270 to correct the anomalies in the [[Tables of Toledo]]; they divided the year into 365 days, 5 hours, 49 minutes, 16 seconds. They were originally written in [[Castillian]]{{Fact|date=January 2008}} and later translated into [[Latin language|Latin]]. [[Georg Purbach]] used the ''Alfonsine tables'' for his astronomy book ''Theoricae novae planetarum''.
The Alfonsine tables were the most popular astronomical tables in Europe until late in the 16th century, when they were replaced by [[Erasmus Reinhold]]'s ''[[Prutenic Tables|Prutenic or Prussian Tables]]'' of 1551 (dedicated to Duke [[Albert of Prussia]]) which were based on [[Nicolaus Copernicus]]'s ''[[De revolutionibus orbium coelestium]]''. Erasmus Reinhold had re-calculated afresh, from Copernicus's basic parameters, a new set of astronomical tables.
