The protagonists of this book are the ignition of civilization and the cornerstones of mathematics, astronomy and medicine - Euclid's "Elements", Ptolemy's "Almagest" and the medical works of the famous ancient Greek doctor Galen. They were created in distant antiquity. After dozens of generations of copying, translation, dissemination and relay in seven cities during the long Middle Ages, they survived until the invention of printing. Since then, they have flourished, promoted the birth of modern science, and are now known as classics. Due to the powerful force majeure, the fire is almost extinguished, and human civilization seems to be plunged into darkness forever. However, thanks to the protection of all parties, the key bridge role played by Arab scholars, and the unremitting efforts of booksellers and printers, the classics that had been hanging by a thread for many times were able to survive and emerge from the siege. This book records the thrilling journey of how the initial achievements of human civilization were passed down from generation to generation across the many obstacles of region, belief, war, and technology.
