Heliodorus of Alexandria was a
Neoplatonist philosopher who lived in the 5th century. He was the son of
Hermias and
Aedesia, and the younger brother of
Ammonius. His father, Hermias, died when he was young, and his mother, Aedesia, raised him and his brother in their home city of Alexandria until they were old enough to go to philosophy school. Aedesia took them to
Athens where they studied under
Proclus. Eventually they returned to Alexandria, where they both taught philosophy. Damascius, who was taught by Heliodorus, describes him as less gifted than his elder brother, and more superficial in his character and studies.
