Alcyone (/ælˈsaɪ.əniː/; Ancient Greek: Ἀλκυόνη, romanized: Alkyóne), in Greek mythology, was the name of one of the Pleiades, daughters of Atlas and Pleione or, more rarely, Aethra.[1] She attracted the attention of the god Poseidon and bore him several children, variously named in the sources: Hyrieus, Hyperenor, and Aethusa;[2] Hyperes and Anthas;[3] and Epopeus.[4][5] By a mortal, Anthedon, Alcyone became the mother of the fisherman Glaucus, who was later transformed into a marine god.[6]
