Hyades

The Hyades were sisters of Hyas and the Pleiades. According to Hyginus in his work Fabulae, Atlas and Pleïone originally had 12 daughters and a son named Hyas (though in Poetica Astronomica, Hyginus contradicted himself, saying that there were 15 daughters). Seven daughters became the Pleiades, but five of them were known as the Hyades. Or else they were daughters of Atlas and the Oceanid Aethra, which would make them half-sisters of the Pleiades. While still others said that the Hyades were daughters of Oceanus and Tethys.

Hyginus named the Hyas' sisters as – Phaesyla, Ambrosia, Coronis, Eudora and Polyxo. In Poetica Astronomica, a poem attributed to Hesiod, their names were Phaesyle, Coronis, Cleeia, Phaeo and Eudora.

Hyginus said that when their brother Hyas was gorged to death by a wild boar or killed by a lion (in the Poetica Astronomica, Hyginus said that Hyas was killed in a lion hunt), five of his sisters died grieving for him. It was said that their weeping brought rain from the sky.

The gods, taking pity on them, immortalised them, placing them in the night sky as a cluster of stars called the Hyades. The Hyades were not far from the star cluster Pleiades, both located within the Taurus constellation.
