All nymphs
Greek · Nereid
Thetis
Thetis is a Nereid, a sea nymph of unusually large mythic importance. She is the mother of Achilles and a figure of prophecy, protection, and divine constraint.
Story shape
A mother with oceanic power
Thetis is courted by gods, married to the mortal Peleus, and bound to the tragic destiny of Achilles. Her sea power does not free her from grief. In epic, she moves between ocean depths and the violence of human war.
Thetis expands the word nymph beyond delicacy: she is political, prophetic, maternal, and formidable.
Tradition boundary
Greek nymphs are minor divinities tied to animate landscape: groves, springs, caves, mountains, and sea foam.
