In Gallo-Roman religion, Sucellus or Sucellos was a god shown carrying a large mallet and an olla. Originally a Celtic god, his cult flourished not only among Gallo-Romans, but also to some extent among the neighbouring peoples of Raetia and Britain. He has been associated with agriculture and wine, particularly in the territory of the Aedui.

An olla is a ceramic jar, often unglazed, used for cooking stews or soups, for the storage of water or dry foods, or for other purposes like the irrigation of olive trees. Ollas have short wide necks and wider bellies, resembling beanpots or East Indian matki.
