There are two Thetis in the Greek mythology:
THETIS, daughter of Uranus and Gaea, belonged to the family of the Titans and was the personification of the humidity of the water, dispenser of luxuriance and fecundity. Joining his brother Oceano he had many children including the nymphs Oceanine, Proteus, Nereus, Doride, as well as all the great rivers known in antiquity including the Nile;
TETI O TETIDE, daughter of Nereus and Doride, the most beautiful of the Nereids (nymphs) who married Peleus from whom she had one of the greatest heroes of antiquity, Achilles. Thetis is represented as a loving mother who, at birth, immersed her son Achilles in the Styx to make him invulnerable, except for the heel.
