The Defense of the Sampo (Sammon puolustus) is a 1896 Romantic nationalist painting by Finnish painter Akseli Gallen-Kallela. The painting illustrates a passage from the Kalevala, the Finnish national epic compiled by Elias Lönnrot in the century.
Some light reading for Nell. Kalevala is the folk epic of Finland. Finnish was one of the biggest influences on Tolkien's Elvish. The stories are gorgeous, full of action but not as bloodthirsty as their Norse cousins.
