Prochoros Kydones (Greek: Πρόχορος Κυδώνης; c. 1330 – c. 1369), Latinized as Prochorus Cydones or Prochorus Cydonius was an Eastern Orthodox monk, theologian, and linguist. An advocate of Western Aristotelian thought, his translation of Latin Scholastic writings, brought him into conflict with Hesychasm, the leading school of Byzantine mystical theology, and its most vigorous defender, Gregory Palamas.
