Thalassia was a primordial goddess of the sea in Greek mythology.
She was the daughter of Aether, the god of air and light,
And Hemera, The goddess of day. Thalassia was the literal body of the sea
And was considered to be the actual personification of the sea's water,
Specifically the water of the Mediterranean.
As a sea deity, Thalassia was considered to be a calm goddess,
And the dangers of the sea were brought about
By the actions of the winds, the Anemoi. . .
