Hyginus Fabulae, 150, the Titanomachy.

     After Juno saw that Epaphus had so much power over his kingdom, though he had been born of a strumpet, she began scheming for Epaphus to be killed while hunting. She also bade the Titans to oust Jupiter from their kingdom and restore it to Saturn. (2) When they began their quest to ascend to heaven, she joined with Jupiter's offspring Minerva, Apollo, and Diana and cast the Titans headlong from the sky. Upon Atlas' shoulders, their leader, she therefore placed the vault of heaven. And he is said to hold up heaven to this day.

     192.1: Atlas had twelve daughters with Pleione or with a daughter of Oceanus, and he had a son named Hyas. When his sisters were lamenting Hyas' death — attacked by a boar or by a lion — they were consumed by the grief. ...ctd. at Hyg. Fab. 192 "Hyas"

     150, Titanomachia. Postquam Iuno uidit Epapho ex paelice nato [i.e. ex Iside] tantam regni potestatem esse, curat in uenatu ut Epaphus necetur, Titanosque hortatur Iouem ut regno pellant et Saturno restituant. (2) hi cum conarentur in caelum ascendere, eos Iouis cum Minerua et Apolline et Diana praecipites in Tartarum deiecit. Atlanti autem, qui dux eorum fuit, caeli fornicem super umeros imposuit, qui adhuc dicitur caelum sustinere.
