There are many within Druidry in general and the OBOD in particular who came from Wicca. Many of these folks have said that Druidry seemed to be a natural progression in their education and direction as pertains to the magic and religion of the Celtic peoples. But why?
The Ovates were the witches, if you will, of the Celtic peoples. The word Ovate comes from the Irish word Fáith which means Seer or one who has the Second Sight i.e. the ability to communicate with the dead and even the power of prophesy. These folks were also known as Piseog (witch) who practiced Piseogacht or witchcraft. The Piseog/Fáith was a local healer, wise or cunning person, and philosopher.
They were a blessing to those who were suffering and a terror to those who were their enemy. Through dispensing herbs to relieve common symptoms they could be very powerful healers. They were also able to speak with those who have passed beyond, relieving the stress of those left behind both for their hopes of better things and their own hopes for a continuation of life. The Piseog/Fáith therefore studied most especially the process of death and dying, and generally things unseen. Considering the above I can see why Wiccans seek to understand the practice of Witchcraft of the ancient Celtic peoples and in turn their religion which we call Druidry.
We can never know what ancient Druidry was really like because we do not know how it related within its ancient social contexts. We can know some particulars but never the full picture and so anyone thinking otherwise is just deluding themselves. However...
Druidry is seeing a come back, albeit a modern one, because people like Ross Nichols. These folks dared to be druids when it wasn't popular or convenient. People aught to thank them instead of vilify them. My question is what have you done that is as good or better? (People always hate mirrors turned on them) Druidry today, has become an acceptible spiritual path in the eyes of many Britians including its aristocracy because of the uprightness of heart and rectitude of conduct of the folks leading it.
I do not think Philip intended to create a seperate path but to show that within Druidry the path of Witchcraft/Seership is already present. Wiccans coming into Druidry do not have to leave what they learned and loved behind but can practice that which speaks to them and continue along a Druidic path.
Considering all the above I must give this book 5 stars.
