Damianus Heliodori (=son of Heliodorus) of Larissa is the author of an introductory work on optics, probably associated with one of the late Neoplatonist institutions of learning (5th/6th century), and perhaps a follower of Ammonius Hermiae in particular. He is not to be confused with Domninus of Larissa.

A less than satisfactory edition with German translation of the Optical Hypotheses was made by Schöne 1897; a new edition with Italian translation is under preparation by Fabio Acerbi. The Hypotheses were transmitted as part of the prefatory materials to Euclid’s Optics.
