David (Greek: Δαυΐδ; fl. 6th century) was a Greek scholar and a commentator on Aristotle and Porphyry.
He may have come from Thessaly, but in later times he was confused with an Armenian of the same name (David Anhaght). He was a pupil of Olympiodorus in Alexandria in the late 6th century. His name suggests that he was a Christian.
Three commentaries to Aristotle's works attributed to him have survived: as well as an introduction to philosophy (prolegomena):
All these works will be published, with an English translation, in the series Commentaria in Aristotelem Armeniaca - Davidis Opera (five volumes), edited by Jonathan Barnes andValentina Calzolari.
Another anonymous commentary on Porphyry's Isagoge which was falsely ascribed to Elias (pseudo-Elias), was also falsely ascribed to David.
