Mercury in Mythology: The Messenger of the Gods

In Egyptian times, it was thought that the planet Mercury was actually two separate stars- one that appeared in the morning (known as Set), and another that appeared in the evening (known as Horus). It’s from Set and Horus where the concept of Mercury’s duality originates.

By contrast, Mercury in Roman mythology is the son of Jupiter and Maia (daughter of Atlas). Depicted as a slender young man with a winged helmet, wings on his feet, and a caduceus (an ancient staff), Mercury’s speed made him a perfect messenger of the gods. As a Roman symbol, he was used to represent communication, speed, travel and knowledge.
