Nice post bro. But to "my knowledge" the Irish Celts didn't start it, I could be wrong. What I do know is that the Celts originated from the South Eastern part of Europe, right on the boarder or Europe and the Middle East. Then migrated all the way up to Ireland. All the books and web sites I've seen all say that the Irish Celts were known as the New Age Celts because they all fled there when Christianity and the Roman's moved in. Here's a link for a list of Celtic holidays, should any one be interested. http://www.packrat-pro.com/celts/celtholidays.htm .
