No, I didn't, I was only familiar with the general mythological concept of the ouroboros. I have to admit that I rather randomly chose this as cool looking motive for Captain Camilla's coin, and then as symbol for Atlantis. (The exact connection between these two will be revealed soon. ;-) )
You know, I always be confused with Ouroboros symbol origin. I heard about multiple origins, like African and Atlantean, but I never knew its confirmed origin.
Just out of curiosity, did you ever read the book "The Worm Ouroboros" by Eddison?
