Lucian's True History

True Stories or True Fictions is a parody of travel tales, by the Greek-speaking Assyrian author Lucian of Samosata, the earliest known fiction about travelling to outer space, alien life-forms and interplanetary warfare. Written in the 2nd century, the novel has been referred to as "the first known text that could be called science fiction". The work was intended by Lucian as a satire against contemporary and ancient sources, which quote fantastic and mythical events as truth.

Lucian's True Stories eludes a clear-cut literary classification. Its multilayered character has given rise to interpretations as diverse as science fiction, fantasy, satire or parody, depending on how much importance scholars attach to Lucian's explicit intention of telling a story of falsehoods.
