This new book combines the latest discoveries with Professor Howell's decades-long study of the Iron Age in Wales to provide a new understanding of the Celtic peoples of South Wales. Readers will encounter a complex and sophisticated society and will then see how that society responded to the Roman invasion and occupation of their territory before considering the nature of the post-Roman world which followed. Professor Howell concludes by outlining a new programme of research, building on recent discoveries, which can take us even further in understanding these fascinating, if at times, enigmatic people.
