The 7th century Scandinavian Warrior in 'Armies of the Dark Ages 600-1066' by Ian Heath is probably based on a
Guldgubber depicting a drinker with a cup without foot (and a spear?). Vendel period. Sorte Muld, Bornholm, Denmark.

A Guldgubber (Gullgubber) [little old man of gold] is some kind of religious object.
