In the Roman mythology, Mercury is regarded as the god of merchants and shopkeepers, as well as travellers and tricksters. He is often associated with the Greek messenger god Hermes. A wily trickster, he was also known for being able to communicate effectively. Apart from being the god of commerce, Mercury was also responsible for sending souls to the underworld. He was also the patron of merchants and thieves, and he was able to control the flow of information.

Like the Greek god Hermes, Mercury was known for challenging the physical and moral boundaries of others. In Roman mythology, he was the only god that could freely cross the underworld. Although Mercury didn't join the Roman Pantheon until the 3rd century BCE, he eventually became a prominent figure in the mythology. Because of his likeness to other gods, such as those depicted in European and Mediterranean cultures, he was easily assimilated into the various cultures that were under the Romans.

The god is often depicted with a caduceus, a wand that can be used to resolve conflicts, and winged sandals that can carry messages for the gods. In Greek mythology, the wand was given to him by Apollo. He was also known for wearing a wide-brimmed hat and carrying a purse, which symbolized his duties as the god of commerce.

Although he was usually depicted in a naked form, Mercury was sometimes seen wearing a cloak and tunic. He wore winged shoes and a winged helm that was made by the god of fire and forge, known as Vulcan. This winged helm eventually became associated with the messenger god.
