Ítem MRS, EDXRF and GC–MS analysis for research on the ritual and funerary areas of Cerro de los Vientos (Baeza, Jaén, Spain). Native and Eastern Mediterranean influences(Elsevier, 2019-12) Sánchez, A.; Tuñón, J. A.; Parras, D. J.; Montejo, M.; Lechuga, M. A.; Ceprián, B.; Luque, A.This paper is about the results obtained from the physico-chemical analysis of the Orientalizing (7th century BC) archaeological materials retrieved from the ritual and funerary areas of the site Cerro de los Vientos (Baeza, Jaén, Spain). The samples under study are native tradition and Phoenician ceramic vessels, and beads of several colours. The analysis used Micro Raman Spectroscopy (MRS) with portable and laboratory equipments, Energy Dispersive X Ray Fluorescence (EDXRF) and Gas Chromatography-Mass Spectrometry (GC–MS). Joint use of these techniques allowed to examine the interaction between the native community of Cerro de los Vientos and the Eastern Mediterranean influence by populations of Phoenician origins. Use of MRS and EDXRF helped identify the mineral and elemental composition of the decorations of the native and Phoenician ceramic vessels, and also of the red and blue beads. Hematite, goethite, amorphous carbon and graphite were recorded in the native pottery. Hematite and manganese oxide were recorded in the Phoenician pottery. The red beads were made of carnelian, a variety of chalcedony that is not found in the Iberian Peninsula. The blue beads were made of glass paste. GC–MS contents analysis identified beeswax in most vessels, both native and Phoenician. The beeswax in native and Phoenician vessels from the area for the funerary feast and in the funerary urns laid in the graves leads to an interpretation in terms of hydromel consumption during feasts and offerings of honey in urns.Ítem The diet of romans during 2nd Punic War in their camp Cerro de las Albahacas (Santo Tomé, Spain) from organic residue analysis in ceramic vessels by GC-MS, HPLC-APCI-MS and GC-C-IRMS methods(2020) Parras, D. J.; Sánchez, A.; Luque, A.; Lechuca, M. A.; Rueda, C.This paper shows the results of chemical analyses performed on a set of ceramic vessels retrieved from the Roman camp built after the battle of Baécula (208 b.C.) on the site known as Cerro de Las Albahacas (Santo Tomé, Jaén, Spain). The paper also assesses the sampling strategy and its influence on the interpretation of the results. A set of 16 ceramic vessels of Iberian typology used by the Roman army was studied in order to analyse the chemical markers associated with their contents. The method consisted in joint use of GC-MS, HPLC-APCI-MS and GC-C-IRMS. The chemical markers identified beeswax and vegetable lipid, mainly in amphorae, while non-ruminant fat is associated with a different type of ceramic vessels. Based on the products identified, the paper puts forward interpretation on the types of food or beverages consumed by Italian-Roman soldiers at the time of the 2nd Punic War.
