Viking society wasn’t homogeneous. They had dealings with many different cultures and they lived in varied environments, from Danish and Swedish pasture to the sub-Arctic tundra of Norway and Iceland. In the early 11th century the best-travelled woman in the world must have been Gudrid Thorbjarnardóttir, whose remarkable journeys demonstrate the great distances the Vikings covered. She gave birth to a child in North America, met people of the First Nations and ate grapes in Vinland, made a pilgrimage to Rome and drank wine in Italy, and died as a nun in Iceland. Vikings lived in close contact with the Sámi people, whom they called Finns. In his earlier book, The Viking Way, Price pointed out that Norwegians and Swedes, at least, might be regarded as in some ways similar to the ‘circumpolar’ cultures which stretch from Greenland to Siberia, notably in what looks like shamanistic behaviour.
That is from Tom Shippey’s excellent LRB Vikings book review, interesting throughout.
