caduceus

noun

Etymology: Via Latin cādūceus, cādūceum, adaptation of Doric Ancient Greek καρύκειον (karúkeion, “herald’s wand or staff”). This and Attic Greek κηρύκειον (kērúkeion) are derived from κῆρυξ (kêrux, “herald, public messenger”). Related to κηρύσσω (kērússō, “to announce”).

1. The official wand carried by a herald in ancient Greece and Rome, specifically the one carried in mythology by Hermes, the messenger of the gods, usually represented with two snakes twined around it.

   “Caduceus the rod of Mercury, / With which he wonts the Stygian realmes inuade […]”

2. A symbol (☤) representing a staff with two snakes wrapped around it, used to indicate merchants and messengers. It is also sometimes incorrectly substituted for the rod of Asclepius as a symbol of medicine.
