The first known ouroboros imagery, where a snake is depicted eating its own tail, appeared in Egypt in the 14th century BC. For these ancient Egyptians, the circular reptile shape symbolized Ra and Osiris. Ancient Greeks used the ouroboros to denote the first earthly being. The gnostics used it as a symbol of the soul of the world, and the list goes on. Many cultures have independently "invented" the elegant ouroboros image to symbolize a version of the same universal idea: there's an eternal cycle of life and death, re-creation and return, a wheel turning forever and ever. This undulating ouroboros ring with turquoise eyes was salvaged from the circumference of a damaged Georgian mourning ring. She looks pretty good slithering solo.
