Cygnus, “The Swan” is connected with several myths. In one of the more popular ones, Cygnus is Zeus. To seduce Leda, wife of Tyndareus, king of Sparta, Zeus took the form of a swan. The offspring from this union were Polydeuces and Castor, who are represented by the constellation Gemini, and the beautiful Helen (Helen of Troy).
