On the Origin of Clockwork, Perpetual Motion Devices, and the Compass

Derek J. de Solla Price's *On the Origin of Clockwork, Perpetual Motion Devices, and the Compass* challenges centuries of misconceptions about humanity's most transformative inventions. Rather than tracing mechanical clocks to simple sundials, this groundbreaking historical study reveals their true ancestors: the sophisticated astronomical machines built by ancient Greek engineers to map the heavens. Through meticulous research spanning two millennia across three continents, Price traces the hidden lineage of timekeeping technology from Hellenic antiquity through the medieval period. He dismantles persistent myths perpetuated through textbooks and shows how crucial innovations—including the magnetic compass borrowed from Chinese sources—were repeatedly lost and rediscovered across generations. The audiobook explores the ingenious mechanics of gearing systems, perpetual motion concepts, and the legendary devices of figures like De Dondi, revealing how medieval inventors built upon forgotten classical knowledge. This non-fiction work reveals how misquotation and legendary histories have obscured our understanding of mechanical innovation. Price, writing as a consultant to the Smithsonian Institution's Museum of History and Technology, provides a lucid, authoritative account that restores accuracy to these pivotal chapters of technological history. Ideal for history enthusiasts, engineers, and anyone curious about how our world's most essential technologies emerged, this audiobook offers a fascinating reassessment of invention, ingenuity, and the remarkable persistence of human knowledge across civilizations.
