What it is

A translation hub where, after the Christian conquest of 1085, teams of clerics, Jews and Mozarabs rendered works of astronomy, medicine, mathematics and philosophy from Arabic into Latin and Castilian, among them the Almagest (Gerard of Cremona, 1175). It was the gateway for Greek and Arabic learning into Latin Europe.

“School of Translators” is a historiographical label: it was not a formal institution but a series of initiatives, that of Archbishop Raymond (1125-1152) and that of Alfonso X (1252-1284), and both the archbishop's exact role and the continuity between the two are debated.

What it led to

  • arrival in Europe of the Almagest, Avicenna, Averroes and al-Khwarizmi's algebra in Latin
  • a boost for the scholastic universities and Latin science
  • Castilian as a language of learning under Alfonso X
