Mercury
Roman god of trade, messages, and boundaries, equivalent to the Greek Hermes
The Myth of Mercury
Mercury entered Roman worship relatively late, around the 5th century BC, when trade with the Greek world brought Hermes' cult to Italy. His name derives from merx, meaning "merchandise," revealing his core identity as a god of commerce. His temple on the Aventine Hill overlooked the Circus Maximus and the busy markets below. Roman merchants formed a guild in his honour and celebrated his festival, the Mercuralia, on 15 May by sprinkling their goods and heads with water from his sacred spring. Unlike the more complex Greek Hermes, Mercury was primarily a patron of profit, though he also guided souls to the underworld and protected travellers on Roman roads.
