Anonymous Commentary on Aristotle, Posterior Analytics I

An anonymous Greek commentary on book 1 of Aristotle's Posterior Analytics was printed by Michael Hayduck in Commentaria in Aristotelem Graeca 21.1 (Berlin, 1907), in the same volume as Eustratius of Nicaea on book 2.

Hayduck gives the excerpt in the preface. It is a Byzantine school commentary on demonstration, definition, and the opening of the Analytics. The compilation is dated, uncertainly, to the twelfth century CE; the edition does not name a commentator. It is not Eustratius's own work, which covers the second book only.

The commentary shows how a twelfth-century teacher worked through the first book beside Eustratius. Hayduck's pages remain the only edition of this short text.
