New findings from a 2,600-year-old grave in Germany suggest the Celts were much more sophisticated than previously thought. Not far from the Heuneburg, the site of an early Celtic settlement, researchers in 2010 stumbled upon the elaborate grave of a Celtic princess. In addition to gold and amber, they found a subterranean burial chamber fitted with massive oak beams.
I love when new data rewrites history or science. I find it exciting, no matter what the subject matter. It is, after all, how we progress.
