X. B. Saintine (1978-1865) was a prolific dramatist who collaborated in more than 200 plays with Eugene Scribe and a noted figure of the Romantic Movement. Jonathan the Visionary (1823) is a collection of fantasy tales told by a mysterious immortal called Jonathan (who is only featured as an active narrator in a few of them). It includes The Story of an Antediluvian Civilization, which retells the history of a civilization from Ethiopia, only a few distant echoes of which survive today. Ranging from prehistorical fantasy to post-apocalypse, it provides a prophetic indication of the manner in which our own civilization might degenerate. The fact that scientific and technological progress is presented here as a symptom of social disease makes Saintine's vision more modern and radical than any of his contemporaries.
