Anyway. The first owner of the farm, the first settler, was buried beneath a mound on the farm when he died, and presumed to hang around the settlement thereafter. It was common to sacrifice a little beer by the mound, and in general try to stay on his good side
I think I remember seeing vessels for some form of drink when I was at the National Museum in Copenhagen last year. But didn't spend a huge time reading the text in their fantastic, recently modernized permanent exhibits on Viking history. Before, I had never been to any major Viking history/museum exhibit.

What a tough, sometimes violent bunch they were, those Vikings.
