We use the word ‘Celtic’ fast and loose – it evokes something mythical and romantic about our past – but what exactly does it mean? Furthermore, why do people believe that there were Celts in Britain and what relationship do they have to the ancient Celts? This fascinating book focuses particularly on how the Celts were re-invented in the sixteenth and seventeenth centuries, and how the legacy of mistaken interpretations still affects the way we understand the ancient sources and archaeological evidence.
