Constellation No 7. - Cygnus (New Version)
In Greek mythology Cygnus is often associate with several distinct legendary swans. Many of which involve gods and people transforming into swan. However, I think my personal favorite is idea that Cygnus, together with other avian constellations near the summer solstic, Vultur Cadens and Aquila, may be a significant part of the origin of the myth of the Stymphalian Birds, one of The Twelve Labours of Hercules.
I wanted to post this in conjunction with the summer solstice but its already the 21st here (but only by less than a hour) so I’m going to say close enough. Enjoy!
