In the Aarne–Thompson classification systems of folktales, 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.
