Alcyone (Greek: ) was a Greek demi-goddess, sometimes regarded as one of the Pleiades. More often she was thought of as the daughter of Aeolus and wife of Ceyx, she had a son called Eosphorus and the king of Thessaly. They were very happy together, but, when Ceyx perished in a shipwreck, Alcyone (whose name means "queen who wards off storms") threw herself into the sea.
