The Caduceus Wand of the Keryx is a most impressive and complex implement. It is the wand of Hermes (also known as Thoth and Mercury), the god of wisdom, magic and communication. Legend has it that Hermes intervened in a fight between two serpents who then curled themselves around his wand. The rod of Hermes represents the balanced forces of eternal light working invisibly in the darkness.
The symbolism of the caduceus is based upon the Qabalistic Tree of Life. The upper point of the wand rests on Kether, and the wings stretch out to Chokmah and Binah, thus comprehending the three Supernal Sephiroth. The lower seven are embraced by the serpents whose heads fall on Chesed and Geburah. These are the twin serpents of Egypt and the currents of the astral light. In addition to this, the wings and the top of the wand form the Hebrew letter Shin, the symbol of Fire. The heads and upper halves of the serpents form the letter Aleph while their tails enclose Mem, the symbol of Water—the Fire of Life above, the Waters of Creation below, and the Air as the Reconciler vibrating between Fire and Water.
