Peter of Toledo
While not much is known of his life, from his fluency in Arabic he is assumed to have been a Mozarab. His activities as a translator suggest he worked at the Toledo School of Translators, which was supported by the archbishop of Toledo, Raymond de Sauvetât. Deficiencies in the translation of Apology of al-Kindy, on which he is known to have worked, indicate that his knowledge of Classical Arabic was limited.
In 1142, Peter the Venerable visited Spain and recruited a team of translators who were to translate five Arabic texts, including the Qur'an. The translation work went on in 1142-3. Peter of Toledo appears to have been the principal translator of only one of the texts, the Apology of al-Kindy, but he played a key role in the project as a whole, collaborating with three other people who were familiar with Arabic, Robert of Ketton, Herman of Carinthia, a Muslim called Mohammed and also with Peter of Poitiers, who undertook the polishing of the Latin. Kritzeck credits Peter of Toledo with having planned and annotated the collection, but this interpretation depends on the Peter being the author of anonymous glosses in a manuscript which has survived in France. 
- Bishko, C. Peter the Venerable's Journey to Spain. Bishko identifies Peter of Toledo as "the probable link between the first translation of the Koran into a western language and Peter (the Venerable)'s anti-Islamic croisade intellectuelle, on the one hand, and the Toletan translators clustered about the cathedral school of Archbishop Raymond, on the other."

- Kritzeck, J. Robert of Ketton's translation of the Qur'an: Peter the Venerable recounted that because Peter of Toledo was not as familiar with Latin as he was with Arabic, he was assisted by another brother, Peter of Poitiers.
