[L ollo-vidios, great tree (?)].
Roman name for a native Celtic god whose worship was known in both Gaul and Britain, closely related to Gaulish Mars, for whom his name is sometimes an epithet. Surviving artefacts suggest that his links to Mars are with healing, fertility, and peaceful protection rather than war. He is seen as a male figure with a small head and elongated body at a site in the English Cotswolds; here he wears a cap and cloak rather than armour and carries an offering saucer and a double cornucopia, implying prosperity. At Customs Scrubs, Gloucestershire, he is seen with sword, shield, and spear, but also with a cornucopia. Under the same spelling, Olloudius was worshipped by the Narbonenses near the present city of Antibes, France.
