Sources of geomaterials in the Sicani Mountains during the Early Middle Ages: A case study of Contrada Castro, central western Sicily

Abstract

From 2017, an unknown rural settlement in Contrada Castro at Corleone (Palermo Province, western Sicily) was investigated as part of the ‘Harvesting Memories Project’. The stratigraphic sequence, supported by radiocarbon dating, has demonstrated a reoccupation of a pre-Roman site during the transition between the Byzantine and Islamic periods. In particular, the main occupation occurred in the late 8th–9th century when pottery kilns and a probable warehouse were constructed. During the 10th–11th century, a new structure with different orientations replaced the previous buildings that had already collapsed. Specifically focusing on a perspective of the household production and its relationship to the surrounding landscapes of this site, this paper presents the results of a geological survey and petrographic analysis of ceramic finds and lithic samples to identify the source area of the geomaterials used in the studied settlement. The ceramic finds were divided into different Paste Groups based on the characteristics of a polarizing microscope study. The use of some locally available raw materials was recorded both for ceramic and lithic samples. Such an approach enables us to better understand ceramic craft technology, clay and lithic procurement strategies and, more broadly, the consumption of household pottery in the Early Medieval site in Contrada Castro. Furthermore, this study verifies the close relationship that this rural settlement had with the surrounding resources in the area and reveals a connection with the city of Palermo during the Early Middle Ages.
