Roman Marble Collections in the Earth Sciences Museum of the University of Bari (Italy): A Valuable Heritage to Support Provenance Studies

The Earth Sciences Museum of the University of Bari (Italy) boasts the presence of a precious and complete nineteenth-century collection of white marbles and colored stones used by the Romans to embellish their buildings and, afterward, reuse in new buildings and artworks for their high symbolic and aesthetic value. This collection, arranged by Francesco and Filippo Belli, consists of 577 samples and a printed inventory and other documents, which allowed to reconstruct the history of the collection. Another collection of 29 marble samples was donated to the museum in 2010 by the Armenise family. Both collections represent a very useful reference tool in provenance studies for marble pieces at the archaeological and artistic sites and for samples of other collections. The systematic organization of these collections and their sharing among scholars, especially through the web network, is clearly essential. The work presented here focuses on the most recent discoveries about Belli’s collection, on the results of the identification of Armenise’s marbles and stones, and above all, on the actions undertaken in recent years in order to valorize this museum’s heritage. Specifically, both collections were reorganized following novel insights about lithotypes and the provenance of each sample, a detailed database including data on each sample was created, and a website reporting information and images of the two collections was built in order to guarantee the correct dissemination of data.
