Sampo
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 works for many days at a mighty forge until he finally succeeds in creating the Sampo: 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 figures such as theosophian Pekka Ervast, historian of religions Uno Harva and the linguist Eemil Nestor Setälä in the early 20th century. According to the archaeologist Elena Kuz'mina the Sampo mill myth  originates from the Indo-European "skambhá" (support, pillar, column), and was borrowed into Finno-Ugric. In the "Atharvaveda" the 'skambhá' is a creature that supports the universe, analogous to the World Tree - the Sampo has been claimed to be the Finnish equivalent of the world tree. Similar devices. In the Aarne–Thompson classification systems of Folk-Tales, tale type 565 refers to a magic mill that continuously produces food or salt. Examples include "Why the Sea is Salt" (Norway, based on the poem "Grottasöngr"), "Sweet porridge" (Germanic), and "The Water Mother" (Chinese). Such devices have been included into modern tales  such as "Strega Nona" (1975, children's book). Variants on the theme with a cautionary tale and pupil-master relationship include "The Master and his Pupil" (English), and Goethe's 1797 poem "The Sorcerer's Apprentice". The Cornucopia of Greek mythology also produces endless goods, and some versions of the Grail myth emphasize how the Grail creates food and goods. Japanese folktale "Shiofuki usu" speaks of a grindstone that could be used to create anything. Like Sampo, it too was lost to the sea, endlessly grinding salt. The Mahabharatha speaks about the Akshaya Patra, a vessel or bowl capable of  creating food. It stopped providing at the end of the day when the lady of the house had her last meal. Similarly in Irish myth the Cauldron of the Dagda ("coire ansic" or "un-dry cauldron") was a magical vessel that satisfied any number of people.
