Johannes Kepler — Somnium
Translated and Introduced by Michael Windsperger
Seu opus posthumum de astronomia lunari.
His posthumous treatise on lunar astronomy
Somnium ("The Dream") by Johannes Kepler is a captivating blend of science fiction, astronomy, and mythology, written in 1608 and published posthumously in 1634. This groundbreaking work explores the possibility of traveling to the Moon, offering a unique perspective on celestial phenomena through the lens of a dreamlike narrative.
The story follows a young Icelandic boy and his mother, a healer and sorceress, who summon a daemon to learn about the Moon. Through the daemon's account, Kepler vividly describes a fantastical journey to the Moon, envisioning what life might be like for its inhabitants and how Earth would appear from a lunar perspective.
This imaginative tale serves as a vehicle for Kepler to explore the astronomical concepts of his time, particularly heliocentrism—the revolutionary idea that the Sun, not Earth, is at the center of the universe. By situating these ideas within a fictional framework, he bridges the gap between scientific thought and creative speculation. The daemon's description of the Moon includes its harsh environment, long day-night cycles, and how its geography might affect its hypothetical inhabitants. Kepler’s portrayal of the Earth as viewed from the Moon invites readers to reconsider their understanding of the universe from a different vantage point.
The work also reflects elements of Kepler's own life. The protagonist’s mother, a central figure in the narrative, is often seen as a nod to Kepler’s real mother, who faced accusations of witchcraft during her lifetime. Through this personal connection, Somnium becomes more than just a scientific or speculative work—it is also a deeply human story about struggle, perspective, and imagination.
Often regarded as one of the earliest examples of science fiction, Somnium remains a testament to Kepler’s visionary thinking. Long before space exploration was conceivable, Kepler dreamed of journeys beyond Earth and introduced readers to the vast possibilities of the cosmos. His work continues to inspire, offering a timeless blend of scientific curiosity and creative wonder.
Our edition is a beautiful tribute to Kepler’s work. The translation by Michael Windsperger stays true to Kepler’s original text while making it accessible to modern readers. It invites you to explore Kepler’s fascinating vision of space and humanity's place in it, presented in a timeless and elegant form.
