Beyond an opening theoretical section lies a detailed analysis of Neolithic pottery evidence from Anglesey and north-west Wales, the Upper Severn Valley, the Usk Valley, Glamorgan and west Wales. With much of the data and dating sequences confined to appendices, Peterson's discussion addresses issues of pottery tradition, standardisation, raw material selection, identity and symbolism through form, style and decoration, and what these tell us about those who made and used Neolithic pottery.
