Ceterum de Coei filiabus Asteria fugiens Iovis complexum in coturnicem mutata seipsam demisit in mare, quae ab ea urbs Asteria appellata fuit, quae postea Delos nomen accepit. Siquidem Latonam ab Iove compressam per universum terrarum orbem Juno insectata est, donec Delum pervenit, atque ibi Dianam prius peperit: qua obstetrice adiuta mater Apollinem deinceps edidit. Enimvero Diana venationis studio delectata, virgo permansit: Apollo autem divinandi facultatem edoctus a Pane Iovis & Contumeliae filio, Delphos, quo tempore Themis illic oracula dabat, se contulit.
--Apollodorus, Bibliothekes I.IV.4, translated into Latin by Thomas Gale (1675)
One of the daughters of Coeus, Asteria, transformed herself into a quail and jumped into the sea in order to escape Jupiter’s assault, and so they named the city Asteria after her for it. Later the city was renamed Delos. When Jupiter raped Latona and Juno pursued her in vengeance, this is where Latona ended up giving birth to Artemis [Diana]. Artemis [Diana] then acted as a midwife to help her mother give birth to her twin brother Apollo. Because Artemis [Diana] loved hunting, she remained a virgin; but Apollo, learning the art of divination from Pan, and went to Delphi, where Themis was giving prophecies.
