Other forms: ouroboroi; ouroboroses
The ouroboros is an ancient spiritual symbol dating back to the 14th century BCE. Depicted as a snake or dragon consuming its own tail, it forms a circular shape representing infinity and the cyclic nature of the universe.
Also sometimes spelled uroboros, this term comes from a Greek word meaning "tail-eater." It was first used in Ancient Egypt and is seen in the tomb of Tutankhamun. It later became a staple of medieval mysticism, representing the eternal cycle of destruction and rebirth. It also illustrates the "All is One" philosophy of alchemy, an ancient practice that combined chemistry and philosophy in a quest to transform and perfect matter.
