This classic study of the druids, one of the three intellectual classes of the early Celtic peoples, was first published by the University of Wales Press in 1966. The druids were the most enlightened and civilizing spiritual influence in Celtic Europe and were held in high regard as priests, philosophers, teachers and judges. Nora Chadwick's book examines and assesses the early written evidence of the Greeks and Romans and considers the druids within their historical context.

The institution of druidism captured the imagination of the ancient classical world. Its appeal has continued to this day. Significant developments in the field during the last thirty years are discussed by Anne Ross in this revised edition, which also includes a map of the major known druidic sites and centres in Europe.

The Druids is a scholarly work of interest and importance to all those who feel the perennial attraction of its subject.
