Celtic deities

The gods and goddesses of the pre-Christian Celtic peoples are known from a variety of sources, including written Celtic mythology, ancient places of worship, statues, engravings, cult objects and place or personal names.

The locus classicus for the Celtic gods of Gaul is the passage in Julius Caesar's Commentarii de Bello Gallico (The Gallic War, 52–51 BC) in which he names six of them, together with their functions. He says that Mercury was the most honoured of all the gods and many images of him were to be found. Mercury was regarded as the inventor of all the arts, the patron of travellers and of merchants, and the most powerful god in matters of commerce and gain. After him, the Gauls honoured Apollo, who drove away diseases, Mars, who controlled war, Jupiter, who ruled the heavens, and Minerva, who promoted handicrafts. He adds that the Gauls regarded Dis Pater as their ancestor.

In characteristic Roman fashion, Caesar does not refer to these figures by their native names but by the names of the Roman gods with which he equated them, a procedure that greatly complicates the task of identifying his Gaulish deities with their counterparts in the insular literatures. He also presents a neat schematic equation of god and function that is quite foreign to the vernacular literary testimony. Yet, given its limitations, his brief catalog is a valuable witness.
