Organic Residue Analysis on Iron Age Ceramic Mugs (5th–1st Century BC) from Valle Camonica—UNESCO Site n. 94, Northern Italy

The paper is dedicated to the study of organic remains in ceramic drinking vessels from protohistoric Northern Italy. These one-handled mugs are a typical item of the prealpine area, dating from the 5th to the 1st century BCE, and possibly carried high cultural value, given their presence in graves and sanctuaries as well as the presence of alphabetic inscriptions on some of them. The sampled items consist of 10 mug bases from the Iron Age sanctuary of Dos dell’Arca (Capo di Ponte, BS) and the coeval settlement of Castello di Castione della Presolana (BG). The analyses included HT-GC-MS and GC-C-IRMS analyses to identify ancient food/beverage products. The results indicate a differentiated use for the two types of mugs (“Breno” and “Dos dell’Arca” types), suggesting a possible shift in cultic habits. While both types were primarily containers for milk consumption, the earliest type was also used for consuming fermented, millet-based beverages, while the latter was covered with some oily vegetal substance before its disposal.
