Thalassa

Thalassa was a primordial sea goddess, a daughter of Aether and Hemera. With the sea god Pontus, she was the mother of the nine Telchines and Halia. According to a myth recounted by Hesiod, she gave birth to Aphrodite when Cronus cut the genitalia of Uranus that subsequently fell into the sea. Thalassa is the personification of the sea itself.

As told in Aesop's Fables, she appears as a woman rising up from the depths of the sea, as well in Roman-era mosaics. In these mosaics, she is depicted with crab claw horns, wearing seaweed, and holding a ship's oar.
