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.

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.
