It was quite a shock to the rest of Europe when the Vikings, who had been raiding in Scandinavia and making little raids occasionally in Europe, pillaged The Holy Isle of Lindisfarne. The Vikings were pumped, though; it was a very profitable day. That was the beginning of the Viking Age. We discuss the Viking Age, why it was clear to the Vikings that raiding (as opposed to thievery) was not a crime, and why Hnefatafl, which everybody calls Viking chess, isn’t really like chess at all.
