[1] Pittheus was a son of Pelops and Dia[2][3] (maybe another name for Hippodamia), father of Aethra[4][5] and Henioche,[6] and grandfather and instructor of Theseus.
Having gathered settlers together and joining the two villages of Hyperea and Anthea into a modern city, Pittheus renamed it Troezen after his sibling.
[12] Bellerophon came to Troezen to ask Pittheus for Aethra's hand in marriage, but the hero was banished from Corinth before the nuptials took place.
'[14] Pittheus understanding the oracle on Aegeus' inquiry whether or not he was going to ever have children, had made the Athenian king drunk, who ended up spending the night with his daughter Aethra.
[15] According to Plutarch, Pittheus merely spread the report of her daughter's copulation with the god so that Theseus might be regarded as the son of Poseidon, who was much revered at Troezen.
But the hero, secretly inspired by the valor of his cousin Heracles, paid no heed of his grandfather's warnings, traveled by the road and eventually cleared it from brigands and bandits that infested it.
When Theseus, now king of Athens, married Phaedra, he sent Hippolytos to the house of Pittheus, who became his pupil and raised him as heir to the Troezen throne.
