Paper given 5 April 2013 at the third meeting of the Austmarr Network, Härnösand, April 5 – 6, 2013. - It is well known that Finno-Ugric peoples, like people further east, had a notion that the polar star was a nail in the top of an invisible world pillar.

To what extent were such notions shared by the (Germanic) Scandinavian neighbours? By Eldar Heide, eldar-heide.net/.
