I’m glad you found it interesting. There’s some really interesting stuff at Celtic Source – especially from a bardic point of view – and I like the balanced way Dr Gwilym Morus-Baird looks at different sides of an argument. He is also makes reference to a book I have, an excellent source in my opinion, The Celtic Heroic Age by John T. Koch – really worth getting your hands on a copy if you are able to.
Just as a clarification, when I say “Celtic” I mean anything and everything in the Celtic-speaking cultures, past and present. I know that the use of the word Celtic has become troublesome for many, so I just hope it’s clear that’s what I mean.
