Pentagram with Ouroboros and Caduceus

The caduceus (from the Greek word "messenger", "harbinger") were: Greco-Roman God Hermes-mercury, God the healer Ashmun Mesopotamia, ancient Egyptian gods Anubis and sometimes ISIS, the Phoenician God of Bal (Baal, Baal), the Sumerian goddess Ishtar and some other gods and goddesses. In Christianity, the caduceus became the symbol of Sophia. On the ancient Orthodox icons she holds it in her right hand.

There are many interpretations of the values of the caduceus. He is the symbol of the key to bring down the limit between light and darkness, good and evil, life and death.
The wings of the caduceus symbolize the ability to cross any boundary (option – are the personification of the spirit), rod power over the forces of nature, double snake - opposite side of the dualism, which, ultimately, must be connected. The two snakes represent the power connection and separation, good and evil, fire and water, etc.
There is an opinion that the rod or staff is the axis Mundi (or world tree), and up and down which, between Heaven and Earth, move the gods-mediators.
Therefore, the Caduceus was worn by all messengers as a sign of peace and protection, and he was their main attribute. Two snakes with heads facing up symbolize in this case evolution and the beginning of the universe (like Yang in Taoism), or interpreted as two mutually conditioned process of evolutionary development of material forms and a shower that govern material forms. The symmetrical arrangement of the snakes and wings is proof of a balance of opposing forces and harmonious development as the lower, physical and the higher, spiritual level.
Snakes are also associated with the cyclical rebirth of Nature and the restoration of universal Order, when it is violated. Quite often they are equated to the symbol of wisdom.
