The ivory workshop of Valencina de la Concepción (Seville, Spain) and the identification of ivory from Asian elephant on the Iberian Peninsula in the first half of the 3rd millennium BC

摘要

During excavations in the huge ditched enclosure of Valencina de la Concepción (Seville, Spain), the main centre from the first hierarchical framework-settlement in the Guadalquivir Valley, a pit with remains of a context for producing ivory artefacts, dating from the first half of the 3rd millennium BC, was discovered in the large metallurgical nucleate workshops. Scientific (Optical Microscopy, FIRT and Raman Spectroscopy, C/N Isotope Ratio Mass Spectrometry) analyses revealed that the ivory belonged to Asian elephants and the archaeological study, which was made in a specialized workshop context. In this paper we present the archaeological context, the study of the ivory artefacts and the state of research on ivory in the Lower Guadalquivir Basin during the 3rd millennium BC. In a parallel way, this paper discusses the significance of this workshop context in the configuration and function of the long distance circulation of raw material and the specialized craft areas in the first political centres.
