Mnemosyne — Classical Greek Myth Library

Asteria is daughter of the Titans Coeus and Phoebe, sister of Leto. Hesiod makes her wife of Perses and mother of Hecate; later mythographers add a separate adventure that aetiologizes Delos. Zeus pursued Asteria; she fled his embrace, changing into a quail (*ortyx*) and casting herself into the sea (or falling as a star). Where she struck the water she became the island Ortygia—“Quail Island”—afterward called Delos, the “Evident” or “Clear” land when it came to rest and received Leto. In this strand the barren, floating rock that alone dares host Leto’s labor is Leto’s own sister in metamorphosed form: kinship explains the island’s pity. Callimachus sings Delos as Asteria who wandered the waves like a star-island until she anchored for Apollo’s birth. Apollodorus notes Asteria among Coeus’s children and, in the Leto sequence, the hunt that ends on Delos—without always spelling the quail-change, which handbooks (Hyginus and scholia) supply. The Homeric Hymn personifies Delos without narrating Asteria’s flight; the metamorphosis line is the classical bridge between Titan sisterhood and Delian cult geography. Catalogue Asteria as Coeus’s daughter who escapes Zeus as quail/star and becomes the island—Ortygia/Delos—where her sister Leto will finally bear Apollo and Artemis.
