Balius and Xanthus

Balius (/ˈbeɪliəs/; Βάλιος, Balios, possibly "dappled") and Xanthus (/ˈzænθəs/; Ξάνθος, Xanthos, "blonde") were, according to Greek mythology, two immortal horses, the offspring of the harpy Podarge and the West wind, Zephyrus; following another tradition, their father was Zeus.

Note: Balius and Xanthus are the Latin forms of the Greek names Balios and Xanthos.

Poseidon gave the two horses to King Peleus of Phtia, as a wedding gift, when Peleus married the Ocean goddess Thetis. Peleus later gave the horses to his son Achilles who took them to draw his chariot during the Trojan War.

Book 16 of the Iliad tells us that Achilles had a third horse, Pedasos (maybe "Jumper", maybe "Captive"), which was yoked as a "trace horse", along with Xanthus and Balios. Achilles had captured Pedasos when he took the city of Eetion. Pedasos was mortal, but he could keep up with the divine horses. Sarpedon, prince of Lycia and ally of Troy, killed Pedasos when his spear missed Patroclus. Achilles' comrade-in-arms Patroclus used to feed and groom these horses. In the Iliad, it is told how, when Patroclus was killed in battle, Xanthus and Balius stood motionless on the field of battle, and wept.
