(Εὔδωρος) is mentioned by Alexander Aphrodisiensis (ad Arist. Metaph. p. 26, ed. Paris. 1536, fol.) as a commentator on Aristotle's Metaphysics, in which he is said to have altered several passages. Simplicius likewise speaks of a Peripatetic philosopher of this name, and relates that he had written on the Aristotelian Categories. We do not know, however, if this be the same person. Eudorus, whom Alexander Aphrodisiensis mentions, was a native of Alexandria, and had, like Ariston of Alexandria, written a work on the Nile. (Strab. xvii. p.790; comp. Fabric. Bibl. Graec. vol. i. p. 845, vol. iii. pp. 172, 492).
