Apollodorus Library 3.13

[1]
  Peleus fled to Phthia to the court of Eurytion, son of Actor, and was purified by him, and he received from him his daughter Antigone and the third part of the country. ¹ And a daughter Polydora was born to him, who was wedded by Borus, son of Perieres. ²

[2] Thence he went with Eurytion to hunt the Calydonian boar, but in throwing a dart at the hog he involuntarily struck and killed Eurytion. Therefore flying again from Phthia he betook him to Acastus at Iolcus and was purified by him. ³

[3] And at the games celebrated in honor of Pelias he contended in wrestling with Atalanta. ⁴ And Astydamia, wife of Acastus, fell in love with Peleus, and sent him a proposal for a meeting; ⁵ and when she could not prevail on him she sent word to his wife that Peleus was about to marry Sterope, daughter of Acastus; on hearing which the wife of Peleus strung herself up. And the wife of Acastus falsely accused Peleus to her husband, alleging that he had attempted her virtue. On hearing that, Acastus would not kill the man whom he had purified, but took him to hunt on Pelion. There a contest taking place in regard to the hunt, Peleus cut out and put in his pouch the tongues of the animals that fell to him, while the party of Acastus bagged his game and derided him as if he had taken nothing. But he produced them the tongues, and said that he had taken just as many animals as he had tongues. ⁶ When he had fallen asleep on Pelion, Acastus deserted him, and hiding his sword in the cows' dung, returned. On arising and looking for his sword, Peleus was caught by the centaurs and would have perished, if he had not been saved by Chiron, who also restored him his sword, which he had sought and found.

[4]
  Peleus married Polydora, daughter of Perieres, by whom he had a putative son Menesthius, though in fact Menesthius was the son of the river Sperchius. ⁷

[5] Afterwards he married Thetis, daughter of Nereus, ⁸ for whose hand Zeus and Poseidon had been rivals; but when Themis prophesied that the son born of Thetis would be mightier than his father, they withdrew. ⁹ But some say that when Zeus was bent on gratifying his passion for her, Prometheus declared that the son borne to him by her would be lord of heaven; ¹⁰ and others affirm that Thetis would not consort with Zeus because she had been brought up by Hera, and that Zeus in anger would marry her to a mortal. ¹¹ Chiron, therefore, having advised Peleus to seize her and hold her fast in spite of her shape-shifting, he watched his chance and carried her off, and though she turned, now into fire, now into water, and now into a beast, he did not let her go till he saw that she had resumed her former shape. ¹² And he married her on Pelion, and there the gods celebrated the marriage with feast and song. ¹³ And Chiron gave Peleus an ashen spear, ¹⁴ and Poseidon gave him horses, Balius and Xanthus, and these were immortal. ¹⁵

[6]
  When Thetis had got a babe by Peleus, she wished to make it immortal, and unknown to Peleus she used to hide it in the fire by night in order to destroy the mortal element which the child inherited from its father, but by day she anointed him with ambrosia. ¹⁶ But Peleus watched her, and, seeing the child writhing on the fire, he cried out; and Thetis, thus prevented from accomplishing her purpose, forsook her infant son and departed to the Nereids. ¹⁷ Peleus brought the child to Chiron, who received him and fed him on the inwards of lions and wild swine and the marrows of bears, ¹⁸ and named him Achilles, because he had not put his lips to the breast; ¹⁹ but before that time his name was Ligyron.

[7]
  After that Peleus, with Jason and the Dioscuri, laid waste Iolcus; and he slaughtered Astydamia, wife of Acastus, and, having divided her limb from limb, he led the army through her into the city. ²⁰

[8]
  When Achilles was nine years old, Calchas declared that Troy could not be taken without him; so Thetis, foreseeing that it was fated he should perish if he went to the war, disguised him in female garb and entrusted him as a maiden to Lycomedes. ²¹ Bred at his court, Achilles had an intrigue with Deidamia, daughter of Lycomedes, and a son Pyrrhus was born to him, who was afterwards called Neoptolemus. But the secret of Achilles was betrayed, and Ulysses, seeking him at the court of Lycomedes, discovered him by the blast of a trumpet. ²² And in that way Achilles went to Troy.
  He was accompanied by Phoenix, son of Amyntor. This Phoenix had been blinded by his father on the strength of a false accusation of seduction preferred against him by his father's concubine Phthia. But Peleus brought him to Chiron, who restored his sight, and thereupon Peleus made him king of the Dolopians. ²³
  Achilles was also accompanied by Patroclus, son of Menoetius ²⁴ and Sthenele, daughter of Acastus; or the mother of Patroclus was Periopis, daughter of Pheres, or, as Philocrates says, she was Polymele, daughter of Peleus. At Opus, in a quarrel over a game of dice, Patroclus killed the boy Clitonymus, son of Amphidamas, and flying with his father he dwelt at the house of Peleus ²⁵ and became a minion of Achilles.
