Ouroboros is a symbol handed down from ancient times to the present. It is roughly represented as a snake swallowing its own tail, resulting in a ring. Its name means "self swallower".

Because of the particularity of Ouroboros symbol, the meanings expressed in different religious groups are different; in addition, with the passage of time, its connotation and meaning are constantly changing.
