Titre : Concretions in votive contexts of mineral waters: the Roman coins of Cuntis (Pontevedra, Spain) Auteurs : Silvia GONZÁLEZ SOUTELO, Xosé Lois MÉNDEZ FERNÁNDEZ, Revue : Archaeology, Society and Environment Numéro : Issue 1 Volume : 1 Date : 2023/03/31 DOI : 10.21494/ISTE.OP.2023.0963 ISSN : 2752-4507 Résumé : Archaeological evidence testifies to the importance of the thermal town of Cuntis (Spain) in Roman times, an aspect that also appears to be reflected in literary sources and in its own toponym. The importance of the beneficial and cultual use of these thermal waters in Roman times is evidenced by the presence of collection wells located in the center of the village of Santa María de Cuntis, in the Burga or ‘Fuego de Dios’. It is the main collection system for the hot springs that supply the current spa, but also because it is a site steeped in an important historical tradition. In 1908, during the cleaning of this well, some objects were discovered and distributed among the neighbors, but by chance some of them were deposited in the Provincial Archaeological Museum of Ourense where they were recently identified. Among them, a key, a knife and some coins that have been altered by the action of mineral-medicinal waters from this source. In this work, we present this discovery, as well as we propose a first approach to the archaeometric study of these concretions, with the interest of evaluating how the different types of water affect the conservation and modification of the archaeological objects preserved in these thermal environments.
