= Alfonso X (1221-1284) was the enlightened King of i.a. Castile and one of the greatest patrons of learning of the Middle Ages. His main scientific interests were astronomy and astrology: he prepared the so-called 'Tablas Alfonsies' (Alfonsine Tables), containing diagrams and figures on planetary movements, and the Libros del saber de astronomia (Books of Astronomical Lore), describing astronomical instruments.
