In Finnish mythology, the Sampo () is a magical device or object described in many different ways that was constructed by the blacksmith Ilmarinen and that brought riches and good fortune to its holder, akin to the horn of plenty (cornucopia) of Greek mythology. When the Sampo was stolen, Ilmarinen's homeland fell upon hard times. He sent an expedition to retrieve it, but in the ensuing battle it was smashed and lost at sea. In the Kalevala The Sampo is a pivotal element of the plot of the Finnish epic poem Kalevala, compiled in 1835 (and expanded in 1849) by Elias Lönnrot based on Finnish oral tradition. In the expanded second version of the poem, the Sampo is forged by Ilmarinen, a legendary smith, to fulfill a task set by the witch queen of Pohjola, Louhi, in return for her daughter's hand. "Ilmarinen, worthy brother, Thou the only skilful blacksmith, Go and see her wondrous beauty, See her gold and silver garments, See her robed in finest raiment, See her sitting on the rainbow, Walking on the clouds of purple. Forge for her the magic Sampo, Forge the lid in many colors, Thy reward shall be the virgin, Thou shalt win this bride of beauty; Go and bring the lovely maiden To thy home in Kalevala." Ilmarinen works for many days at a mighty forge until he finally succeeds in creating the Sampo: On one side the flour is grinding, On another salt is making, On a third is money forging, And the lid is many-colored. Well the Sampo grinds when finished, To and fro the lid in rocking, Grinds one measure at the day-break, Grinds a measure fit for eating, Grinds a second for the market, Grinds a third one for the store-house. Later, Louhi steals the Sampo, and then Ilmarinen and Väinämöinen enter her stronghold in secret and retrieve it. Louhi pursues them and combats Väinämöinen. In the struggle, Louhi is vanquished but the Sampo is destroyed. Interpretation The Sampo has been interpreted in many ways: a world pillar or world tree, a compass or astrolabe, a chest containing a treasure, a Byzantine coin die, a decorated Vendel period shield, a Christian relic, etc. In the Kalevala, compiler Lönnrot interpreted it to be a quern or mill of some sort that made flour, salt, and gold out of thin air. The world pillar/tree hypothesis was argued for by
