Thalassa (/θəˈlæsə/; Ancient Greek: Θάλασσα, romanized: Thálassa, lit. 'sea';[2] Attic Greek: Θάλαττα, Thálatta[3]) was the general word for 'sea' and for its divine female personification in Greek mythology. The word may have been of Pre-Greek origin[4] and connected to the name of the Mesopotamian primordial sea goddess Tiamat.[5]
