John Sarrazin was probably a friend of John of Salisbury. He may have written his commentary on the "Celestial Hierarchy" of pseudo-Dionysius in around 1140. Then, in around 1167, he may have translated the works of Dionysius. Until this point, theologians in the Latin-speaking West had had to read Dionysius using the ninth-century translation made by Johannes Scotus Eriugena, which was not easy to understand. In contrast, Sarrazin produced a clearer version which was used by Albert the Great and Thomas Aquinas, and had a significant effect on later European mystical writing. Only in the thirteenth century, with the translation of Dionysius made by Robert Grosseteste, and then the fifteenth century translation of Ambrose Traversari, did Sarrazin's translation become superseded.
