This contribution reports the archaeometric study of four black fragmented pieces and one small red pedestal stored in the reserves of Villa Adriana, Tivoli. They were petrographically studied to know the lithology, before any isotopic comparison was performed. C and O stable isotopes and EPR similarity to the available databases helped to assign the provenance. Lapis basanites, Black Göktepe and Ain el Kasir in Tunicia were the most likely raw materials.
