The Mouse Turned into a Maid is an ancient fable of Indian origin that travelled westwards to Europe during the Middle Ages and also exists in the Far East. The story is Aarne-Thompson type 2031C in his list of cumulative tales, another example of which is The Husband of the Rat's Daughter.

There, a holy man grants a mouse's successive wishes to become more than itself until it is changed into a woman fair enough to catch a king's eye. When she dies soon after in an accident, a mood-changing opium plant grows from her burial place. The ancient Indian fable was eventually translated into Pahlavi and then into Arabic, but before a version of any of these works had reached Europe the fable appeared in Marie de France's Ysopet as a cautionary tale against social climbing through marrying above one's station. The creature involved is an ambitious field mouse who applies to the sun for the hand of his daughter. He is sent on to a cloud, the wind, a tower, and then the mouse that undermines it, to the humbling of his aspirations. The theme of keeping to
