The story of the Sampo is told in the Finnish epic “Kalevala,” which was compiled from the poems and songs of Finnish oral traditions. The Sampo was a powerful and mysterious device that had a lid of many colors, three mills on its sides, and produced endless fortune. Outside of this description, however, no one really knows exactly what the Sampo was or what it looked like.
The story of the Sampo found its beginning with a bard and sage as old as the earth itself, Vainamoinen. Vainamoinen was washed up on the shores of the evil land of Pohjola. This land was also the evil counterpart of the land of heroes, called Kalevala, from which Vainamoinen came and where the Finnish epic gets its name.
