Who serves as the messenger god in Roman mythology?

In Roman mythology, the messenger god is Mercury. He is known for his speed and ability to travel freely between the mortal and divine worlds. Mercury is often depicted wearing winged sandals and a winged helmet, emphasizing his swift nature. He serves as a mediator and communicator among the gods and between gods and humans, delivering messages and guiding souls to the afterlife.

Mercury's Greek counterpart is Hermes, who shares many attributes, including the role of a messenger. His additional responsibilities include overseeing trade, travel, and thievery, reflecting his multifaceted nature within Roman belief. This association with messages and communication solidifies Mercury's position as the quintessential messenger god in the Roman pantheon.

Janus, while important in Roman mythology, is the god of beginnings, gates, transitions, and time, rather than a messenger. Jupiter is the king of the gods and represents authority and governance, and Neptune is associated with the sea and earthquakes, neither of whom fulfill the role of a messenger as Mercury does.
