Caduceus

The caduceus is a staff carried by Hermes. George and Martha are entwined in it with wings on its top.. It is the symbol of Hermes and Hermes' cabin.

It is sometimes confused with the Staff of Asclepius, which only has one snake.

History
When Hermes was a child he snuck off from his cave and stole a herd of sacred cattle from Apollo, the Sun god. Outraged, Apollo tracked Hermes down and demanded that he return his cattle. As a sign of forgiveness, Hermes crafted a lyre, a type of musical instrument, which he then gave to Apollo. Accepting the gift, Apollo and Hermes became friends. Soon after, Hermes became an Olympian.

Hermes then crafted the reed pipes, another instrument. When Apollo saw the pipes, he begged Hermes to give them to him. Hermes made a deal with Apollo- he would give him the reed pipes in exchange for the gift of prophecy and Apollo`s golden wand- the Caduceus. Apollo agreed to the deal, then became the god of music. Hermes got the caduceus, and it has been the symbol for him ever since.

The Sea of Monsters
Hermes takes the caduceus with him in different forms, like a modern phone. For example, when going to Camp Half-Blood to talk to Percy. He also takes the caduceus with him again when he delivers a letter to Percy from Poseidon. It turns into a pen so Percy can sign for it.

The Last Olympian
Hermes takes the caduceus to Olympus when going to talk to Annabeth and Percy. He turns it into a high voltage cattle prod, threatening them with it when he is angered.

Percy Jackson and the Staff of Hermes
