The Ouroboros (Greek Ουροβόρος, from ουροβόρος όφις “tail-devouring snake”, also spelled Ourorboros, Oroborus, Uroboros or Uroborus, in English pronounced /ʊˈrɒbɔrɔs/ or /ˌjʊəroʊˈbɒrəs/), is an ancient symbol depicting a serpent or dragon swallowing its own tail and forming a circle. The Ouroboros often represents self-reflexivity or cyclicality, especially in the sense of something constantly re-creating itself, the eternal return, and other things perceived as cycles that begin anew as soon as they end
