Caduceus :  Caduceus: A rod with two snakes entwined about it topped by a pair of wings.

The caduceus served as the symbol of Hermes and Mercury, the Greek and Roman messenger gods. The caduceus was the sign of a herald and hence a logical symbol for the messenger.

Because of a misconception, the caduceus became the insignia of the U.S. Army Medical Corps. The Medical Corps should have chosen the symbol of medicine, which is the rod of Aesculapius , which has only one snake and no wings atop it. No wings were necessary since the essence of medicine is not speed. The single serpent that could shed its skin and emerge in full vigor represents the renewal of youth and health -- medicine.

The Latin word "caduceus" came from the Greek "karykeion," from "karyx" or "keryx" meaning "herald."

The ancient caduceus with its pair of snakes coiled about each other resembles somewhat a model of the structure of double helix ) which was only discovered in modern times (in 1953, if that is still in "modern times").
