Man in the Moon
In J.R.R. Tolkien's Middle-earth folklore as set forth from the Hobbits, the Man in the Moon is described as being an old being who secretly hid on the island of the Moon, and built his minaret there. Combined with the Elven lore, as presented in the legendarium of The Silmarillion, the Man in the Moon of the Hobbits' tales must have his origins in the legend of Tilion the Maia.
This story must also be in turn the origin of our tradition of the Man in the Moon.
This is alluded to further in Tolkien's Roverandom, where the Man in the Moon also lives in a Minaret.
