Thetis
nymphΘέτις
Sea nymph mother of Achilles
Thetis was a sea nymph so powerful that both Zeus and Poseidon desired her — until a prophecy warned her son would surpass his father.
The Myth
Zeus and Poseidon married her to the mortal Peleus. Their wedding was attended by all the gods — and the uninvited Eris, whose Apple of Discord caused the Trojan War. Thetis tried to make Achilles immortal by dipping him in the Styx. Throughout the Iliad, she intercedes for her son.
