The Metamorphoses of Ovid, Books VIII-XV

Thetis being a woman of extraordinary beauty, it is not improbable, that in the Epithalamia that were composed on her marriage, it was asserted, that the Gods had contended for her hand, and had been forced to give way, in obedience to the superior power of destiny. Hyginus says that Prometheus was the only person that was acquainted with the oracle; and that he imparted it to Jupiter, on condition that he would deliver him from the eagle that tormented him: whereupon the God sent Hercules to Mount Caucasus, to perform his promise. It was on the occasion of this marriage that the Goddess Discord presented the golden apple, the dispute for which occasioned the Trojan war. The part of the story which relates how she assumed various forms, to avoid the advances of Peleus, is perhaps an ingenious method of stating, that having several suitors, she was originally disinclined to Peleus, and used every pretext to avoid him, until, by the advice of a wise friend, he found means to remove all the difficulties which opposed his alliance with her.

Some writers state that Thetis was the daughter of Chiron; but Euripides, in a fragment of his Iphigenia, tells us that Achilles, who was the son of this marriage, took a pride in carrying the figure of a Nereid on his shield. The three sons of Æacus were Peleus, Telamon, and Phocus; while they were playing at quoits, the latter accidentally received a blow from Peleus, which killed him. Ovid, however, seems here to imply that Peleus killed his brother purposely.

The story of Chione most probably took its rise from the difference between the inclinations of the two children that she bore. Autolycus, being cunning, and addicted to theft, he was styled the son of Mercury; while Philammon being a lover of music, Apollo was said to be his father. According to Pausanias, Autolycus was the son of Dædalion, and not of Chione. The story of the wolf, the minister of the vengeance of Psamathe, for the death of Phocus, is probably built on historical grounds. Æacus had two wives, Ægina and Psamathe, the sister of Thetis; by the first he had Peleus and Telamon; by the second, Phocus. Lycomedes, the king of Scyros, the brother of Psamathe, resolved to revenge the death of his nephew, whom Peleus had killed: and declared war against Ceyx, for receiving him into his dominions. The troops of Lycomedes ravaged the country, and carried away the flocks of Peleus: on which prayers and entreaties were resorted to, with the view of pacifying him; which object having been effected, he withdrew his troops. On this, it was rumoured that he was changed into a rock, after having ravaged the country like a wild beast, which comparison was perhaps suggested by the fact of his name being partly compounded of the word λυκὸς, ‘a wolf.’
