“The Ouroboros is a Greek word meaning “tail devourer,” and is one of the oldest mystical symbols in the world. It can be perceived as enveloping itself, where the past (the tail) appears to disappear but really moves into an inner domain or reality, vanishing from view but still existing.
The ouroboros has several meanings interwoven into it. Foremost is the symbolism of the serpent biting, devouring, or eating its own tail. This symbolizes the cyclic Nature of the Universe: creation out of destruction, Life out of Death. The ouroboros eats its own tail to sustain its life, in an eternal cycle of renewal. It is sometimes depicted in a lemniscate shape (figure eight) as well.”
