Margaret Cavendish

Other early works of significance include the alternate world found in the Arctic by a young noblewoman in Margaret Cavendish's 1666 novel, The Description of a New World, Called the Blazing-World, the account of life in the future in Louis-Sébastien Mercier's l'An 2440, and the descriptions of alien cultures in Jonathan Swift's Gulliver's Travels (1726) and in Ludvig Holberg's Niels Klim's Underground Travels, an early example of the Hollow Earth genre.

In 1733, Samuel Madden wrote Memoirs Of the Twentieth Century, in which the narrator in 1728 is given a series of state documents from 1997–1998 by his guardian angel, a plot device which is reminiscent of later time travel novels although the story does not explain how the angel obtained these documents.
