Although she was forced to abandon her home and her family and taken to a cold and foreign country, Oreithyia accepted her fate. She was a faithful wife and bore Boreas' two winged sons, Zetes and Calais, and two daughters, Chione, the mother of Eumolpus, and Cleopatra, who later became the wife of the Thracian king Phineus. In Greek mythology, Boreas was the personification of the wild north wind. He is usually shown as a bearded man with winged shoulders and feet to accentuate his impetuous character.
