This is the first of a two-volume edition of Alexander of Aphrodisias commentary on Aristotles Metaphysics. The new edition, which includes a philosophical and philological introduction, as well as notes on textcritical issues, is based on a critical evaluation of the entire manuscript tradition of the commentary. It also takes into account its indirect tradition and the Latin translation of Juan Ginès Sepúlveda.
