Theagenes of Rhegium in Wikipedia
Theagenes of Rhegium (Θεαγένης ὁ Ῥηγῖνος) was a Greek literary critic of the sixth century BC. He is noted for having defended the mythology of Homer, from more rationalist attacks. In so doing he became an early proponent of the allegorical method of reading texts.
None of his work is known to survive. Its effects were felt later.
