I'm always amazed by the celts, and the lady of Vix is a new addition to my body of knowledge regarding the complexity and dominance of their culture.

I'm expect that you're already a fan, but if not I am going to be so happy to introduce you to Dan Carlin's Hardcore History - specifically the most recent episode "Celtic Holocaust", about Ceaser's abject destruction of the once super powerful Celtic people. You'd love it.
