Boreas was known for his abduction of Orithyia, the daughter of King Erechtheus of Athens. Boreas wooed Orithyia, but she declined many times. Boreas eventually decided to take her by force, covering her in a cloud, spiriting her away, and transforming her into his immortal wife. She would bear him an immortal daughter, Khione, and two mortal sons, Calais and Zethes. With his brother; Zephyrus, Boreas dwelt in the mountains of Thrace. Boreas' winds can be powerful and violent, causing great destruction.
He was said to have fathered twelve colts after taking the form of a stallion, to the mares of Erichthonius, king of Dardania. These were said to be able to run across a field of grain without trampling the plants. He is also said to have fathered three giant Hyperborean priests of Apollo by Chione.
Boreas was the father of the Thracian Butes by a nymph named Pitys, who was driven insane by Dionysus when he seduced Coronis, one of his Maenads.
He was frequently shown as a winged old man with shaggy hair and beard, holding a conch shell and wearing a billowing cloak. He was said to wear a tunic.
Boreas was depicted as being very strong, with a violent temper to match.
