Tyro

In Greek mythology, Tyro (Ancient Greek: Τυρώ ) was a Thessalian princess.

Tyro was the daughter of Salmoneus and Alcidice, and she married Cretheus but loved Enipeus. Tyro gave birth to Pelias and Neleus, the twin sons of Poseidon. With Cretheus she had Aeson, Pheres, and Amythaon.[1][2][3] In some accounts, Tyro had a daughter named Phalanna who gave her name to city of Phalanna in Thessaly.[4]

Her father, Salmoneus, was the brother of Athamas and Sisyphus. Tyro was married to her uncle Cretheus,[5] whom she bore three sons, Aeson, Amythaon, and Pheres. However, she loved the river god Enipeus, who refused her advances. One day, Poseidon, filled with lust for Tyro, disguised himself as Enipeus and from their union was born Pelias and Neleus, twin boys. Tyro exposed her sons on a mountain to die, but they were found by a herdsman who raised them as his own. When the twins reached adulthood, they found Tyro and killed her stepmother, Sidero, for having mistreated their mother (Salmoneus married Sidero when Alcidice, his wife and the mother of Tyro, died). Sidero hid in a temple to Hera but Pelias killed her anyway, causing Hera's undying hatred of Pelias – and her glorious patronage of Jason and the Argonauts in their long quest for the Golden Fleece.[6] Pelias' half brother Aeson, the son of Tyro and Cretheus, was the father of Jason.[7] Soon after, Tyro married Sisyphus, her paternal uncle and had two children. It was said that their children would kill Salmoneus, so Tyro killed them in order to save her father.[8]

Ezra Pound refers to Tyro in The Cantos. In Canto 2 he takes up her rape by Poseidon:

"And by the beach-run, Tyro, Twisted arms of the sea-god, Lithe sinews of water, gripping her, cross-hold, And the blue-gray glass of the wave tents them, Glare azure of water, cold-welter, close cover."

In a later Canto (74) Pound connects her to Alcmene, imprisoned in the world of the dead, but in a later paradisal vision he sees her "ascending":

thick smoke, purple, rising bright flame now on the altar the crystal funnel of air out of Erebus, the delivered, Tyro, Alcmene, free now, ascending [...] no shades more (Canto 90)[9]
