- How much "difference training" is there, and why did they decide to combine them, I wonder. Dentistry seems so different than medicine.
A caduceus (/kəˈduːsiəs/, -ʃəs, -ˈdjuː-; kerykeion in Greek; Unicode U+2624 (☤) on the Miscellaneous Symbols table) is a winged staff with two snakes wrapped around it. It was an ancient astrological symbol of commerce and is associated with the Greek god Hermes the messenger for the gods, conductor of the dead and protector of merchants and thieves. It was originally a herald's staff, sometimes with wings, with two white ribbons attached. The ribbons eventually evolved into snakes.
The symbol's origins are thought to date to as early as 2600 BC in Mesopotamia, and there are several references to a caduceus-like symbol in the Bible, namely in Numbers 21:4–9, and 2 Kings 18:4. During the Exodus, Moses was instructed by God to fashion a pole upon which he was to position a serpent made of bronze; when looked upon, this Nehushtan, as it was called in Hebrew, would spare the lives of the Israelites
stricken by venomous snake bites. The intent was that people would look upward and be reminded to pray to God, but eventually the meaning was forgotten and this symbol was apparently worshiped by the Hebrew people until the reign of Hezekiah as described in 2 Kings 18:4.
