Orithyia (/ɒrᵻˈθaɪ.ə/;Greek: Ὠρείθυια Ōreithuia; Latin: Ōrīthyia) was the daughter of King Erechtheus of Athens and his wife, Praxithea, in Greek mythology.
Orithyia's brothers were Cecrops, Pandorus, and Metion, and her sisters were Procris, Creusa, and Chthonia.
Boreas, the north wind, fell in love with her. At first he attempted to woo her, but after failing at that he decided to take her by force, as violence felt more natural to him. While she was playing by the Ilissos River she was carried off to Sarpedon’s Rock, near the Erginos River in Thrace. There she was wrapped in a cloud and raped.Aeschylus wrote a satyr play about the abduction called Orithyia which has been lost.
Plato writes somewhat mockingly that there may have been a rational explanation for her story. She may have been killed on the rocks of the river when a gust of northern wind came, and so she was said to have been 'taken by Boreas'. He also mentions in another account she was taken by Boreas not along the Ilissos, but from the Areopagus, a rock outcropping near the Acropolis where murderers were tried. However, many scholars regard this as a later gloss.
