 Three works attributed to Elias have been published: a commentary on Porphyry’s Isagoge, a commentary on Aristotle’s Categories (both in Commentaria in Aristotelem Graeca Vol 18) and a third, highly truncated work on Aristotle’s Prior Analytics (see Westerink 1961). The author of these works may have been a pupil of Olympiodorus, and in that case it is quite possible that the commentary on the Isagoge was composed in the form of a transcript of Olympiodorus’ lectures.
