Elias (Greek scholar)
Elias was a Greek scholar and a commentator on Aristotle and Porphyry.
He was a pupil of Olympiodorus in Alexandria in the late-6th century. His name suggests that he was a Christian. A commentary on Porphyry's Isagoge written in Greek has survived. Some fragments survive of a commentary he wrote on the Prior Analytics of Aristotle, and he is known to have written on the De Interpretatione of Aristotle. It is also possible that the extant Commentary on Aristotle's Categories which is attributed to David was actually written by Elias.
In addition, a second extant commentary on Porphyry's Isagoge was falsely ascribed to Elias. The commentary was also falsely ascribed to David, and it has been conjectured that it may have been written by Stephen of Alexandria.
