“ THETIS Thetis, the daughter of Nereus and Doris, was so beautiful that Jupiter himself sought her in marriage; but having learned from Prometheus the Titan that Thetis should bear a son who should grow greater than his father, Jupiter desisted from his suit and decreed that Thetis should be the wife of a mortal. By the aid of Chiron the Centaur, Peleus succeeded in winning the goddess for his bride and their son was the renowned Achilles. ”
