Rome: white marbles in the Fora of Caesar, Augustus, and Trajan

Statistical processing of the analyses carried out on the marbles sampled in the Imperial Fora clearly indicates that the large majority of the architectural pieces -almost 85%- originate from the Luna quarries. Proconnesian and Pentelicon marbles are occasionally present, especially in the Forum of Caesar but not only, and demonstrate that assorted marble varieties were used probably in the course of later re-building and restorations. Statuary white marbles much used in the antiquity, such as Pentelicon, Parian, and dolomitic Thasian from Cape Vathy were identified among the samples drawn from the decoration and the sculptures used to embellish the Fora of Augustus and Trajan
