In Greek mythology, Thalassa (Greek: Θάλασσα "sea") is a primordial sea goddess, daughter of Aether and Hemera. With sea god Pontus, she was the mother of the nine Telchines and Halia. Sometimes, she was thought of as the mother of Aphrodite with Uranus or with Zeus. She is the personification of the Mediterranean Sea. The word is also used for "sea" in the Greek Bible, eg. Genesis 1:10 and Mark 1:16. Alternative names are Thalatta and Thalath.
