Abstracts

In spite of the great leap forward experienced in our understanding of the use of marble and other ornamental stones in Roman Spain, provenance studies are still quite uncommon in some territories of the Iberian Peninsula. This was the case of the northwesternmost part (modern Galicia), where no significant work had been done until now. Within the framework of an interdisciplinary study, a significant number of objects studied did not match with the main well-known Classical marbles but seemed to have been produced with a local stone known as O Incio marble, which had never been yet archaeometrically analysed. Therefore, the quarries near the small village of O Incio were located and sampled, and a multi-method approach combining polarized-light microscopy, cathodoluminescence, X-ray powder diffraction and stable C and O isotope analysis as well as spectrophotometry was applied to characterize the different outcropping marble varieties as the first and basic step to correctly differentiate them from other Iberian and foreign marbles with similar macroscopic features.

Marble use in Roman Gallaecia (NW Spain): an unaddressed question

Marble was one of the noble material most widely used in the Roman world. Since late Republican times and in particular during the Imperial Age, the use of decorative marbles became fashionable in Rome. Marble was especially sought-after to be used in architecture and the plastic arts and, in opposition to other stones, its use was often linked with self-representation of the display of status, either from an individual, a family or even a social/political group (such a town). All sort of marbles were widely employed to produce a large number of objects, from sculptures, inscriptions, sarcophagi or even furniture, as well as to decorate all sorts of buildings and public spaces. Among them, white marbles had a prominent place. The western provinces of the Roman Empire were not an exception and soon after their conquest and control by Rome, they followed the example set by the Urbs and adopted the use of m...
