Hermes is the Greek god of trade, travel, and communication. He is also the messenger of the gods and the patron god of merchants, thieves, and athletes. Hermes is known for his cunning and mischievous nature, as well as his ability to move quickly and easily between the different realms of the world. He is often depicted carrying a staff called the caduceus, which is entwined with two snakes and is a symbol of his role as a messenger. Hermes is also commonly associated with the Roman god Mercury.
