This bronze statue depicts Mercury a messenger of the gods and a god of trade in the Roman religion (Original name Mercurius).

Carrying the caduceus, a herald's staff with two entwined snakes, shows how the Roman religion was syncretized with the Greek religion, where Hermes plays a very similar role and carries the same symbols.
Mercury was the most popular God in Britain and Gaul and was regarded as the inventor of all the arts.
