UROBORO (also spelled OUROBOROS,etc…) represents a serpent or a dragon biting its own tail and forming a circle. It appeared in almost all ancient cultures and had been important in religious and mythological symbolism, but has also been frequently used in alchemical illustrations, and was used to symbolise concepts such as completion, totality and perfection. It can be also seen as a circular never ending process where end meets start. This cyclic motion is typically encountered when collecting antiques. It is a coming and going of objects from the past, situations re-presented, vibrations of déjà vu. Every time such objects changes proprietary, the cycle starts again.
