The Arabs undertook large-scale efforts at translation. Having conquered the Greek world, they made Arabic versions of its philosophical and scientific works. During the Middle Ages, translations of some of these Arabic versions were made into Latin, chiefly at Córdoba in Spain. King Alfonso X el Sabio (Alphonse the Wise) of Castille in the 13th century promoted this effort by founding a Schola Traductorum (School of Translation) in Toledo. There Arabic texts, Hebrew texts, and Latin texts were translated into the other tongues by Muslim, Jewish and Christian scholars, who also argued the merits of their respective religions. Latin translations of Greek and original Arab works of scholarship and science helped advance European Scholasticism, and thus European science and culture.
