Based on the idea that pottery is a good indicator of changes in past societies, the current project aims to: (1) contribute to our knowledge of prehistoric Galician pottery, especially in terms of style, technology and the chaîne opératoire of manufacturing procedures and (2) confirm previous hypotheses on the relation between pottery characteristics and their chrono-cultural and spatial contexts. Another important goal of the project is to elucidate the mechanisms of circulation that evolved in the NW of the Iberian Peninsula during various time periods beyond this territory.
This project is the continuation of a line of research funded as a part of the INCITE R&D&I program of the regional government of Galicia (Xunta, 2007-9), during which 423 potsherds were analysed, ranging from the Mid-Neolithic to contemporary times, 289 of which were prehistoric. It is necessary to widen the number of samples to validate and extend the results of this project by applying modern analytical techniques.
In order to meet these objectives, the present project proposes two research lines: (1) a general characterisation of the new set of ceramics samples and (2) to apply modern analyses that produce fresh knowledge on the style, manufacturing techniques and origins of prehistoric pottery. For the first line of research, 84 new samples from 14 Galician Neolithic and Bronze Age (5500-1000 BC) settlements and 50 sediment samples from five different areas in the region will be examined. Methods that will be employed are: assessment of mineralogical composition (XRD), analysis of trace and light elements (XRF), C and N elemental analysis and quantitative colour assessment of pottery ware and decorations (CIELAB system). For the second line, innovative analytical approaches will be applied to a selection of 25-50 samples of the new and previously analysed ceramics series, using XRD, pyrolysis-GC/MS and electron microscopy (SEM), in combination with archaeo-malacological and experimental approaches. This will allow for the detailed assessment of how the parent materials were processed, the molecular composition of the organic matter, firing technologies, firing temperatures, the relation between firing temperature and pottery colour, and decoration techniques.
Other goals of the project, related to knowledge transfer, are firstly the development of an archaeological and archaeometrical database and secondly the disclosure of results in a scientific and socio-cultural environment.
In short, this study will allow for the continuation of an innovative, productive and unique research line in Galician Archaeology, and its results will facilitate a new model that may be applied to other pottery contexts and territories.
