Provenance of the white and polychrome marbles used for the architecture and sculpture of roman Sentinum (Sassoferrato, Marche, Italy)

Abstract

AbstractSamples from 22 white crystalline and one greco scritto‐like marble artefacts (first–third centuries ce) from Roman Sentinum (Sassoferrato, Italy) were analysed to determine their provenance by thin‐section microscopy, X‐ray diffraction and stable isotope ratio analysis (δ18O and δ13C). Polychrome marbles were provenanced through macroscopic examination. Results show that relief sculpture and statuary were carved in white marble from Carrara, Paros, Thasos and Naxos. Architectural white marbles were identified as Proconnesian for veneer, and Proconnesian, Parian, Dokimeion and Thasian for capitals and pediments. Polychrome lithotypes include foremost africano, breccia di Sciro, cipollino verde, giallo antico, bardiglio and greco scritto (from Ephesos‐Hasançavuslar).
