In Greek mythology, Thrassa (Ancient Greek: Θράσσα, romanized: Thrássa, lit. 'Thracian'^[1]), was the daughter of Ares and Tereine, daughter of the river-god Strymon. Hipponous, son of Triballos (eponym or god of the Triballoi (Τριβαλλοί) tribe of Thrace), married her and they had a daughter called Polyphonte. This daughter scorned the activities of Aphrodite and went to the mountains as a companion and sharer of sports with Artemis. Thus, the goddess of love made her fall in love with a bear and drove her mad. Polyphonte eventually coupled with a bear and bore the ursine giants Agrius and Oreion.^[2]
