Tiamat (“the deep”) was the Assyrian goddess of the sea named for the Assyrian (Semitic) word Tamtu for sea, of the same etymological root as the Hebrew word Tehom, and apparently the Pelasgians (Semitic as well) brought that word to the Aegean where the Greek goddess of the sea was Thalassa, that word for sea (and thalassocracy) in the name Kushasthali now submerged in the Gulf of Kutch.
