Ross Nichols was one of the key figures in the revival of interest in Celtic Spirituality and Druidry in modern times. In 1964, Nichols, a Cambridge academic and published poet, became Chief of The Order of Bards Ovates & Druids, and from that time, he wrote prolifically on the subjects of Druidism and Celtic mythology

Ross Nichols’ The Book of Druidry, was published after his death in 1990, and eleven years later remains in print in English and foreign editions, while The Order of Bards Ovates and Druids, which he founded, is now probably the largest Druid organisation in the world, with many thousands of members worldwide.

In 2002 In The Grove of the Druids – The Druid Teachings of Ross Nichols introduced and edited by Philip Carr-Gomm with a foreword by Ronald Hutton was published by Watkins Books.
