Asclepius of Tralles and the Alexandrian Commentaries

Asclepius of Tralles was a 6th-century CE Neoplatonic philosopher from Tralles in Lydia. He studied at Alexandria under Ammonius Hermiae, alongside figures such as Simplicius of Cilicia, in the final phase of the pagan philosophical schools of the Eastern Roman Empire.

Two lecture commentaries survive under his name. One records scholia on Nicomachus of Gerasa's Introduction to Arithmetic; the other sets out notes on the first seven books of Aristotle's Metaphysics (Alpha through Zeta). Both are hypomnemata compiled from Ammonius's seminars, not independent treatises—a format shared with other Ammonius pupils such as John Philoponus.

The commentaries belong to the Alexandrian tradition that treated Aristotle's logic, mathematics, and metaphysics as steps toward Platonic theology. The Metaphysics scholia are a principal witness to Ammonius's teaching where his own commentary on that work is lost. Editions by Hayduck (1888) and Tarán (1969) remain the standard references.

Modern scholarship values Asclepius for his role in transmitting late antique Aristotelian and Neoplatonic exegesis. His work documents how 6th-century teachers harmonized Aristotelian doctrine with Platonism for an advanced philosophical curriculum in Christian Byzantium.
