A type of black gloss‐finished pottery produced from the 4th century through to the 1st century bc in southern Italy. Three main source areas are traditionally recognized: A ware produced in the Naples area; B ware from kilns in coastal Etruria; and C ware from eastern Sicily. However, chemical analysis of samples from excavations in Calabria suggests that the threefold classification is overly simplistic and that at least half a dozen other kilns were producing imitations of Campanian vessels outside the core production areas. After the 1st century bc its popularity was eclipsed by red gloss‐finished Samian ware. Campanian ware was traded widely in the central Mediterranean and is sometimes found in Gaul from the 3rd century bc; very occasional finds have been reported from Silchester, Hampshire, and Ower, Dorset, in southern England. Local copies of Campanian ware plates and cups were produced in southern France in a variety of fabrics through the 1st century bc.
