Acaste (Oceanide)

In Greek mythology, Acaste (Greek: Ακαστη, Akaste, "unstable" or "irregular") was one of the Oceanides and, thus, a daughter of Oceanus and Tethys.

Acaste only appeared in one myth, along with her sisters, as a companion of Persephone. Persephone recounted her kidnapping to her mother in the following passage:

All we were (i.e. Persephone and her companions) playing in a lovely meadow, Leucippe and Phaeno and Electra and Ianthe, Melita also and Iache with Rhodea and Callirhoe and Melobosis and Tyche and Ocyrhoe, fair as a flower, Chryseis, Ianeira, Acaste and Admete and Rhodope and Pluto and charming Calypso; Styx too was there and Urania and lovely Galaxaura with Pallas who rouses battles and Artemis delighting in arrows: we were playing and gathering sweet flowers in our hands, soft crocuses mingled with irises and hyacinths, and rose-blooms and lilies, marvellous to see, and the narcissus which the wide earth caused to grow yellow as a crocus.
