Spain was so dynamic a center of medieval Arabism as to draw scholars from throughout Christian Europe, notably Gerard of Cremona, Herman of Carinthia, Michael Scotus, and Robert of Ketton. In 1143, Robert of Ketton made the first Latin translation of the Qur'an, at the request of Peter the Venerable, abbot of Cluny. Marcos de Toledo produced another translation of the Qur'an in the 13th century under a mandate from archbishop Rodrigo Ximénez de Rada, who later edited the landmark "Historia Arabum" ("history of the Arabs"), drawing on the work of al-Razi for the knowledge of al-Andalus prior to the Almoravid conquest.
