Arignotus

Arignotus was a Pythagorean in the time of Lucian—that is, the 2nd century CE—who was renowned for his wisdom, and had the surname of ἱερός ("the holy"). He is described as telling a story of a time he exorcised a demon that was haunting a home. Other scholars disagree with this hypothesis.

There is an unrelated, otherwise unknown Arignotus mentioned in Aeschines's speech Against Timarchus.
