Aedesius (died 355), Neoplatonist philosopher, was born of a noble Cappadocian family. He migrated to Syria, attracted by the lectures of Iamblichus, of whom he became a follower. According to Eunapius, he differed from Iamblichus on certain points connected with theurgy and magic. He taught at Pergamum, his chief disciples being Eusebius and Maximus. He seems to have modified his doctrines through fear of Constantine.
