Druidism Options

Hey, I was wondering if anyone knew anything about original ancient druidism, before the druid revival and neo-druidry and stuff. Druidry has always fascinated me, but i get the impression this whole druid revival thing is only a blurry shadow of what druidism is supposed to be; somewhat like wicca in regards to magic. I know it's kind of a broad topic, but I'm curious to know what the differences are between druidry and neo-druidry, if anyone knows of any good books on the subject, and any general thoughts you might have. Thanks:)

While I agree that we know alot about the druids and the celts for that matter, from my own research I am hard pressed to believe that any modern day revivalist movement really ressembles the celtic societies of old. Firstly everybody in those celtic traditions are considered druids. In real celtic society you had a cast system that if I remember correctly basically boilded down to four casts - slaves, civilians, warriors and druids. Secondly we just don't know enough to really truely replicate a celtic druid order. For example many of those 20,000 thousand poems you mentioned are lost to time or the real words were christainized. Now I will not dispute there are Druidic orders that are in the likeness of days gone by. But I wouldn't by into any order that claimed to know the exact tradition. That to me is only new age.
