Myths about Wedding of Peleus and Thetis

At his magnificent wedding to the sea-nymph Thetis on the slopes of Mount Pelion, King Peleus received a pair of immortal horses, Balius and Xanthus, as a divine gift from the god Poseidon. These swift steeds, born of the West Wind and a Harpy, were capable of human speech and legendary speed, later becoming the prized chariot-bearers of Peleus's son, Achilles, during the Trojan War.
