History of Cygnus

Double origin for this constellation. She first alludes to the swan that Zeus seemed to seduce Leda, daughter of Th├ęstios, king of Aetolia & wife of Tyndare, king of Sparta. From their loves were born Pollux & Helen as well as Castor and Clytemnestre. The second origin refers to Cycnos, king of Liguria. The latter was the friend of Phaeton, son of the Sun God Helios, who was struck down by Zeus when he tried to drive the chariot of the sun. Consumed by the death of his friend, Cycons was transformed into a swan & transported to the sky to relieve his pain.
