Thespius

Thespius was reportedly son of Erechtheus, King of Athens,[2] and possibly Praxithea, daughter of Phrasimus and Diogeneia.

[3] He was probably the brother of Protogeneia, Pandora, Procris, Creusa, Oreithyia, Chthonia,[4] Merope,[5] Cecrops, Pandorus, Metion,[3] Orneus,[6] Eupalamus[7] and Sicyon.

All his daughters came of marrying age but Thespius seems to have sought no husband for them; he instead desired grandchildren from the hero Heracles.

In this version, only forty-nine slept with the hero, with the fiftieth being destined to serve as a virgin priestess of a temple to Heracles, as a punishment for her refusal to sleep with him.

According to Hellanicus, a certain Sthephanephoros ("crown bearer") was called one of the sons of Heracles who were born from the daughters of Thestios.
