when Python was pursuing her, and there clinging to an olive, she gave birth to Apollo and Artemis. Hera, despite being enraged that Asteria had defied her and allowed Leto to give birth to the products of Zeus' liaison, did no harm to Asteria, out of respect for her for not sleeping with Zeus when he chased her, and instead preferring the sea over him, thus not further defiling Hera's marriage. Asteria's power to withstand Hera's threats seems to stem from her parentage as the daughter of two Titans. A different version was added by the poet Nonnus who recounted that, after Asteria was pursued by Zeus but turned herself into a quail and leapt into the sea, Poseidon instead took up the chase. In the madness of his passion, he hunted the chaste goddess to and fro in the sea, riding restless before the changing wind and thus she transformed herself into the desert island of Delos with the help of her nephew Apollo who rooted her in the waves immovable. The element of Asteria fleeing from Zeus as the origin of Delos was probably introduced by Callimachus, as in the Homeric Hymn to Apollo, nothing in the conversation between Leto and Delos indicates of such a past for Delos, let alone that they are sisters. Like the Hymn, however, Callimachus does not allude to the kinship between Leto and Asteria either, in contrast to Hesiod, who recorded that they are sisters but did not make Asteria the origin of Delos. Asteria as Delos is already known since Pindar, but whether he would have known of the story of her trying to avoid Zeus is not clear. In the rare account where Asteria was the mother of Heracles by Zeus, the Phoenicians sacrifice quails to the hero because when he went into Libya and was killed by Typhon, Iolaus brought a quail to him, and having put it close to him, he smelt it and came to life again.
