According to classical mythology, the wedding of Thetis and Peleus was celebrated on Mount Pelion, outside the cave of Chiron, and attended by the deities: there they celebrated the marriage with feasting. Apollo played the lyre and the Muses sang, Pindar claimed. At the wedding Chiron gave Peleus an ashen spear that had been polished by Athene and had a blade forged by Hephaestus. While the Olympian goddesses brought him gifts: from Aphrodite, a bowl with an embossed Eros, from Hera a chlamys while from Athena a flute. His father-in-law Nereus endowed him a basket of the salt called 'divine', which has an irresistible virtue for overeating, appetite and digestion, explaining the expression '...she poured the divine salt'. Zeus then bestowed the wings of Arce to the newly-wed couple which was later given by Thetis to his son, Achilles. Furthermore, the god of the sea, Poseidon gave Peleus the immortal horses, Balius and Xanthus. Eris, the goddess of discord, had not been invited, however, and in spite, she threw a golden apple into the midst of the goddesses that was to be awarded only to the fairest. In most interpretations, the award was made during the Judgement of Paris and eventually occasioned the Trojan War.
