The Caduceus
(artwork by Nicolas Raymond)


Noun. Plural caducei. Late 16th century.
[Latin caduceus, -um from Doric Greek karuk(e)ion = Attic kerukeion, neuter adjective used as noun, from kerux, -uk- herald.]

In CLASSICAL HISTORY, a Greek or Roman herald's wand;
specifically (also capitalised Caduceus) the wand carried by the messenger-god Hermes or Mercury,
usually represented with two serpents twined round it.

Here's some trivia for you: What does the Caduceus represent? If you said Hermes, Mercury, their wands or the messages they bore in their capacity as messenger-gods, then well done you, and I would hazard a guess that you either did a term of classical history in school or you actually read the above definition of Caduceus before moving on to my inane ramblings. If, however, you said the medical profession, doctors or healing, then a big, loud, Family Fortunesque buzzer in your ear. Or maybe not.
The Rod of Asclepius on the Star of Life
The problem is that the Caduceus is often confused with the Rod of Asclepius, the difference being that the Rod of Asclepius is usually portrayed as a genuine staff (rather than a wand or sceptre) with a single serpent entwined around it. Crucially, it is also an authentic symbol of medicine, as Asclepius, the son of Apollo and Coronis, was instructed in the art of healing by the centaur Chiron, and even knew how to bring the dead back to life. After being killed by Zeus, Asclepius was proclaimed the god of medicine, having been held to have been the first physician. Thus, his symbol, that of his staff with a single serpent wound about it, is the familiar symbol of doctors today.

So what of the Caduceus? Isn't that also used as a symbol of medicine? Well, yes, but erroneously, originating with the US Army Medical Corps in the mid-19th century, seemingly as a result of simple ignorance of both classical mythology and iconography. Its use as such stuck, however, particularly in the US, even though many commentators have written that the Caduceus is a wholly inappropriate symbol for doctors, being the wand of Hermes, the trickster god of traders and thieves, conductor of souls to the underworld. Thus, the Caduceus has historically been more fittingly used as an emblem of commerce. 

Are you a doctor?

Do you use the Caduceus as your symbol?

Does your doctor know his Asclepius from his pancreas, his Hermes from his herpes, and his Venus from his ... oh never mind.

  1. You are incorrect, as the sybullogy of this predates Greek.

  2. What a health educative post has been dropped here. I was impressed much going the deep into the caduceus snakes' background. This was fabulously knowledgeable and of course enriched my medicine learning. Proclaiming god of medicine by the son of Apollo -Asclepius, about the the US Army Medical Corps all information were very learn-able and excited finding so much precious info altogether. Now, medical science has been developed at the highest label and different types of invention of medical instruments even you will see the new POS software has been developed for the dispensary level, is a live example. BTW I was really charmed with what you have presented.
