Caduceus
Encyclopedia
The caduceus is the staff carried by Hermes
in Greek mythology
. The same staff was also borne by heralds in general, for example by Iris
, the messenger of Hera
. It is a short staff entwined by two serpents, sometimes surmounted by wings. In Roman iconography it was often depicted being carried in the left hand of Mercury
, the messenger of the gods, guide of the dead and protector of merchants, shepherds, gamblers, liars and thieves.
As a symbolic object it represents Hermes (or the Roman Mercury), and by extension trades, occupations or undertakings associated with the god. In later Antiquity
the caduceus provided the basis for the astrological symbol
representing the planet Mercury
. Thus, through its use in astrology
and alchemy
, it has come to denote the elemental metal
of the same name.
By extension of its association with Mercury/Hermes, the caduceus is also a recognized symbol of commerce and negotiation, two realms in which balanced exchange and reciprocity are recognized as ideals. This association is ancient, and consistent from the Classical period to modern times. The caduceus is also used as a symbol representing printing, again by extension of the attributes of Mercury (in this case associated with writing and eloquence).
The caduceus is sometimes mistakenly used as a symbol of medicine and/or medical practice
, especially in North America
, because of widespread confusion with the traditional medical symbol, the rod of Asclepius
, which has only a single snake and no wings.
Lewis Richard Farnell
(1909) in his study of the cult of Hermes assumed that the two snakes had simply developed out of ornaments of the shepherd's crook used by heralds as their staff. This view has been rejected by later authors pointing to parallel iconography in the Ancient Near East.
It has been argued that the staff or wand entwined by two snakes was itself representing a god in the pre-anthropomorphic era. Like the herm
or priapus
, it would thus be a predecessor of the anthropomorphic Hermes of the classical era.
(1910) discovered that symbols similar to the classical caduceus sometimes appeared on Mesopotamian cylinder seals. He suggested the symbol originated some time between 3000 and 4000 BCE, and that it might have been the source of the Greek caduceus. A.L. Frothingham incorporated Dr. Ward's research into his own work, published in 1916, in which he suggested that the prototype of Hermes was an "Oriental deity of Babylonian extraction" represented in his earliest form as a snake god. From this perspective, the caduceus was originally representative of Hermes himself, in his early form as the Underworld god Ningishzida
, "messenger" of the "Earth Mother".
The caduceus is mentioned in passing by Walter Burkert
as "really the image of copulating snakes taken over from Ancient Near Eastern tradition".
In Egyptian iconography, the Djed
pillar is depicted as containing a snake in a frieze of the Dendera Temple complex
.
The rod of Moses
and the brazen serpent are frequently compared to the caduceus, especially as Moses is acting as a messenger of God to the Pharaoh at the point in the narrative where he changes his staff into a serpent.
. Apollo in return gave Hermes the caduceus as a gesture of friendship.
The association with the serpent thus connects Hermes to Apollo
, as later the serpent was associated with Asclepius
, the "son of Apollo".
The association of Apollo with the serpent is a continuation of the older Indo-European dragon
-slayer motif. Wilhelm Heinrich Roscher
(1913) pointed out that the serpent as an attribute of both Hermes and Asclepius is a variant of the "pre-historic semi-chthonic serpent hero known at Delphi as Python
", who in classical mythology is slain by Apollo.
One Greek myth of origin
of the caduceus is part of the story of Tiresias
, who found two snakes copulating and killed the female with his staff. Tiresias was immediately turned into a woman, and so remained until he was able to repeat the act with the male snake seven years later. This staff later came into the possession of the god Hermes, along with its transformative powers.
Another myth suggests that Hermes (or Mercury) saw two serpents entwined in mortal combat. Separating them with his wand he brought about peace between them, and as a result the wand with two serpents came to be seen as a sign of peace.
In Rome, Livy
refers to the caduceator who negotiated peace arrangements under the diplomatic protection of the caduceus he carried.
and the metal named for Mercury, the caduceus became an important symbol in alchemy
.
The crucified serpent was also revived as an alchemical symbol for fixatio, and John Donne

Iconography
In some vase paintings ancient depictions of the Greek kerukeion are somewhat different from the commonly seen modern representation. These representations feature the two snakes atop the staff (or rod), crossed to create a circle with the heads of the snakes resembling horns. This old graphic form, with an additional crossbar to the staff, seems to have provided the basis for the graphical sign of Mercury (☿) used in Greek astrology from Late Antiquity.Use in alchemy and occultism
