Contribution to the use of marble in Central-<em>Lusitania</em> in Roman times: The stone architectural decoration of <em>Ammaia</em> (São Salvador da Aramenha, Portugal)

This paper reports the results of a quantitative and qualitative study of the imported architectural decorative stone of the Roman town of Ammaia (São Salvador da Aramenha, Portugal), located centrally in the province of Lusitania. All studied ornamental stones were counted, weighed, classified and their provenance was determined. Six types of stone were used for the architectural decoration at Ammaia: white marble, pink–purple limestone, grey– white marble, two marble breccias and granite. Granite was the most widely used building stone and was used for the production of columns and capitals. Previous studies have established a local source for the Ammaia granite (Taelman et alii in press). The provenance of the remaining ornamental stones is primarily regional (the southern part of the Iberian Peninsula). Only the two marble breccia varieties were imported from the Mediterranean: africano from Teos (Turkey) and breccia di Sciro from the island of Skyros also (Greece). The predominant use of regionally available stones is observed in other Roman towns located in the interior of the Iberian Peninsula, such as Emerita Augusta, Asturica Augusta and Munigua, and results mainly from the geographic location of the sites, remote from any seaport and/or navigable river
