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.
The gods and goddesses, or deities of the Celts are known from a variety of sources, these include 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.
In all, several hundred names containing a Celtic element are attested in Gaul.
The majority occur only once, which has led some scholars to conclude that the Celtic gods and their cults were local and tribal rather than national.
Many Celtic divinities were extremely localised, sometimes occurring in just one shrine, perhaps because the spirit concerned was a genius loci, the governing spirit of a particular place.
In Gaul, over four hundred different Celtic god-names are recorded, of which at least 300 occur just once.
He also presents a neat schematic equation of god and function that is quite foreign to the vernacular literary testimony.Sequana was confined to her spring shrine near Dijon, Sulis belonged to Bath.The divine couple Ucuetis and Bergusia were worshipped solely at Alesia in Burgundy.Yet, given its limitations, his brief catalog is a valuable witness.The gods named by Caesar are well-attested in the later epigraphic record of Gaul and Britain.
