About 1,700 years ago, in chilly, rocky Orkney in the Northern Isles of Scotland, some Iron Age humans had a party. It wasn’t just any party: According to archaeologists who have been digging in the highlands since 2006, it featured a huge meat roast (with so many meats!) and gifts of jewelry and involved everyone in the community. But the party, explained The Cairns’ site director in a recent report, is evidence of much more than just a good time.
