An expert in the field of the Roman army, Webster can also lay a claim to have been one of the modern founders of the study of Roman pottery in Britain and to have done pioneering studies in many of the more obscure areas of Romano-British studies, ranging from his early work on the use of coal in Roman Britain through to his last major work, on Romano-Celtic religion.
