About Cygnus
Cygnus is visible during the summer months in the northern hemisphere. The star in the lower left hand corner of the Summer triangle is where the wings meet the body of the swan. The body of the swan is four stars to the right of the summer triangle star, then to the left of that star is another star that forms the head. Lines of stars spread forth from their common root star to form the wings, so that it looks like a swan soaring through the night sky. Cygnus is also known as the Summer Cross for its fair likeness to the Christian icon.

The Myth Behind the Constellation When the Gods and Goddesses were still young and humanity was in its infancy, there was a war upon Mt. Olympus. After which the Gods divided the three realms among themselves. Zeus was to rule the Heavens and Hades was to rule the Underworld, Poseidon the seas. Now Poseidon wished to visit Gaia, or Earth, land. Athena competed with him, and he lost the right to visit the land, a restriction imposed upon his children as well. Now his son was exposed to land soon after his birth, so he was left to die upon the beach. A swan flew over and took pity on the poor infant. She took him in and nursed him back to perfect health. He later became king of a city north of Troy. Now he was not the best king. When he heard a rumor that his new wife was in love with his son he had all of his children sent out to sea, and he stabbed his wife. A loving marriage, don't you think? In an attempt to redeem himself, he helped his neighbor Troy during the Achilles onslaught. He met his demise in a face to face battle with Achilles himself. Poseidon, grief ridden, turned him into a swan to forever fly among the stars.
