Orithyia (daughter of Erechtheus)

[7] Orithyia gave Boreas two daughters, Chione and Cleopatra (the wife of Phineus) and two sons, Calais and Zetes, both known as the Boreads.

[8] These sons grew wings like their father and joined the Argonauts in the quest for the golden fleece.

[15] Because she was in Thrace with Boreas, she did not die when her sisters who either committed suicide or were sacrificed so that Athens could win a war against Eleusis.

[citation needed] In the Posthomerica of Quintus Smyrnaeus, she gave Penthesileia a very swift horse when she visited Thrace.

It is said that prior to the destruction of a large number of barbarian ships due to weather during the Persian War, the Athenians offered sacrifices to Boreas and Oreithyia, praying for their assistance.
