The question has been brought up where can we discuss Druids in a historical sense. May I suggest Celtic Law?

The Brehons were the longest survivors of the old Druidic class, lasting well into the 1600s. Boards could be added to discuss the history of the other ancient teachings such as a Cainte or a Fili.


As for Caesar, I posted this elsewhere but its worth repeating I think.

I recently read a very interesting theory about the role of Druids in Celtic society. Sean B. Dunham in an article Caesar's perception of Gallic social structures puts forth the theory that we may have the role of the Druid all wrong. Whereas the modern view of them is that of priests, that in actuality they had the tripartite duties of priests, philosophers and judges. The ancient world didn't have the separation of church and state that we do now. Instead of being a mysterious magician priests, they actually were an oligarchical elite with both judicial and religious duties.

If so, it appears that Caesar had a much clearer picture of the Druids and the Celts than many have given him credit for. He understood the importance of the Druids which quite possibly accounts for his very harsh treatment of them. They held the history, the law, the wisdom, the religion of their society. Once this was removed, much of what made them Celts also eventually vanished.
