Cissonius (also Cisonius, Cesonius) was an ancient Gaulish/Celtic god. After Visucius, Cissonius was the most common name of the Gaulish/Celtic Mercury; around seventeen inscriptions dedicated to him extend from France and Southern Germany into Switzerland.[1]

Cissonius was represented either as a bearded, helmeted man riding a ram and carrying a wine cup, or else as a young man with winged helmet and herald's staff accompanied by a rooster and goat.[citation needed]

The name has been interpreted as meaning "courageous", "remote"[citation needed] or else "carriage-driver".[2] He was probably a god of trade and protector of travellers, since Mercury exercised similar functions in the Roman pantheon.

In one inscription from Promontogno in Switzerland, Cissonus is identified with Matutinus.[1]

The name of Niederzissen, a village in northern Rhineland-Palatinate, may be derived from the name of Cissonius.[citation needed]

A goddess Cissonia is also recorded.[3]
