The image of Ouroboros (a snake eating its own tail) is usually associated with stars and Egyptian mythology as represented in Roman gnostic intaglios. Ouroboros is continuously re-birthing itself and depicted as a circle, representing eternity and the cyclical nature of things that start once they end. It is also the symbol of duality and dualising power.
