The Caduceus of Hermes

The Greek Hermes found his analogue in Egypt as the ancient Wisdom god Thoth, as Taaut of the Phoenicians and in Rome as the god Mercury (all linked with a magic rod with twin snakes).

The mythical origin of his magic twin serpent caduceus is described in the story of Tiresias. Poulenc, in "Les Mamelles de Tiresias" (The Breasts of Tiresias) tells how Tiresias--the seer who was so unhelpful to Oepidus and Family- found two snakes copulating, and to separate them stuck his staff between them. Immediately he was turned into a woman, and remained so for seven years, until he was able to repeat his action, and change back to male. The transformative power in this story, strong enough to completely reverse even physical polarities of male and female, comes from the union of the two serpents, passed on by the wand. Tiresias' staff, complete with serpents, was later passed on to Hermes...

Occult Hermetic Connection: An occult description of the Caduceus of Hermes (Mercury) is that the serpents may represent positive and negative kundalini as it moves through the chakras and around the spine (the staff) to the head where it communicates with MIND by intellection, the domain of Mercury [wings].

Caduceus Power Wand sold at occult, new age & witchcraft stores such as Abaxion with descriptions such as "It's central phallic rod represents the potentiality of the masculine, and is intimately surrounded by the writhing, woven shakti energies of two coupling serpents. The rod also represents the spine [sushumna] while the serpents conduct spiritual currents [pranas] along the ida and pingala channels in a double helix pattern from the chakra at the base of the spine up to the pineal gland".

According to occultists, there are three principal nadis (Sanskrit for channel) in the human body. The sushumna (the spinal column through which the life-forces flow), by which means we enter and leave the body, the Ida (refreshment and stimulation of spirit), which is associated with the higher mind or manas and the Pingala, (reddish-brown), associated with kama or the force of desire. (G. de Purucker "Man in Evolution" ch. 15 & 16; and "Fountain-Source of Occultism", pp. 458-63).

Hermetic: There are few names to which more diverse persons and disciplines lay claim than the term "Hermetic". Alchemists have applied the adjective "Hermetic" to their art, while magicians (not the entertaining type) attach the name to their ceremonies of evocation and invocation. Followers of Meister Eckhart, Raymond Lull, Paracelsus, Jacob Boehme, and most recently Valentin Tomberg are joined by academic scholars of esoterica, all of whom attach the word "Hermetic" to their activities.

The most abiding impact of Hermeticism on Western culture came about by way of the heterodox mystical, or occult, tradition. Renaissance occultism, with its alchemy, astrology, ceremonial magic, and occult medicine, became saturated with the teachings of the Hermetic books. This content has remained a permanent part of the occult transmissions of the West, and, along with Gnosticism and Neoplatonism, represents the foundation of all the major Western occult currents. Hermetic elements are demonstrably present in the Rosicrucian and Theosophical movements.

The caduceus in pseudo-science: There are amazing claims that a Caduceus Power Wand has zero impedance and infinite resonance!

The caduceus as a Medical symbol: The link between Hermes and his caduceus and medicine seems to have arisen by Hermes links with alchemy. Alchemists were referred to as the sons of Hermes, as Hermetists or Hermeticists and as "practitioners of the hermetic arts". By the end of the sixteenth century, the study of alchemy included not only medicine and pharmaceuticals but chemistry, mining and metallurgy. Despite learned opinion that it is the single snake staff of Asclepius that is the proper symbol of medicine, many medical groups have adopted the twin serpent caduceus of Hermes or Mercury as a medical symbol during the nineteenth and twentieth centuries.

Like the staff of Asclepius, the caduceus became associated with medicine through its use as a printer’s mark, as printers saw themselves as messengers of the printed word and diffusers of knowledge (hence the choice of the symbol of the messenger of the ancient gods). A major reason for the current popularity of the caduceus as a medical symbol was its ill informed official adoption as the insignia for the Medical Department of the United States Army in 1902.
