Leto was a Titaness of the second generation, daughter of Coeus and Phoebe. She was loved by Zeus and conceived twins by him; but Hera, in her jealousy, forbade any land that lay beneath the sun from giving Leto refuge for her labor. The hidden floating island of Delos — said by some traditions to have been beneath the waters until that moment — agreed to receive her, on condition that her divine son should there have his temple. There, after a labor of nine days and nights, attended by Eileithyia (whom Hera had at first detained, but who at last came), Leto bore Artemis first and then, with Artemis's assistance, Apollo. Mother and twins were thereafter inseparable; and when, in later days, the mortal Niobe boasted of her many children that she was greater than Leto with her two, Apollo and Artemis came in vengeance and shot down Niobe's seven sons and seven daughters, leaving her childless and turning her at length, as she wept, into a stone perpetually weeping (the famous "Niobe rock" on Mount Sipylus in Asia Minor).

Curator’s note
What the sources say, and what later tradition added. The sources for this bay
Leto's labor on Delos is in the Homeric Hymn to Apollo 25–139, the principal text. The Niobe vengeance is in Homer (Iliad 24.602–617) and in many subsequent tellings. Leto's cult at Delos was substantial, as the mother of the divine twins to whom the great pan-Hellenic sanctuary was dedicated; she had additional cult in Lycia (where she was sometimes considered native) and at Argos.
