Oribasius's major works, written at the behest of Julian, are two collections of excerpts from the writings of earlier medical scholars, a collection of excerpts from Galen and the Medical Collections (Ἰατρικαὶ Συναγωγαί, Iatrikai Synagogai; Latin: Collectiones medicae), a massive compilation of excerpts from other medical writers of the ancient world.
