There are stories behind the Caduceus. The one story is where Hermes stole some of Apollo's sacred cattle. To appease for what he did, Hermes fashioned a lyre. Apollo, in awe of the lyre, traded Hermes his staff. Another is one where Hermes had found two intertwined snakes, battling each other. He took his staff and drove in between the two snakes and brought peace between them.
Through the months in preparation on my tattoo, in which is now the Caduceus on my back, I did research in finding the meaning of this symbol has it has popped up a few times in meditations, along with the Ankh and the Blood (or Knot) of Isis. During that time I also broke down the Caduceus into the parts that make up it.
