Micromegas: A Philosophical History

Le Micromégas is a 1752 novella by the French philosopher and satirist Voltaire. Along with his story "Plato's Dream", it is an early example in the literary genre of science fiction and has its place in the development of the history of literature. Some uncertainty surrounds the first publication of Micromégas, with possible editions dating to 1751 or as early as 1739, but with the widely accepted publication being 1752.

The tale recounts the visit to Earth of a being from a planet circling the star Sirius, and of his companion from the planet Saturn.

The technique of using an outsider to comment on aspects of Western culture was popular in this period; Voltaire also used it in Zadig. Montesquieu, too, applied it in Persian Letters, as did José Cadalso in Cartas marruecas and Tomás Antônio Gonzaga in Cartas Chilenas.
