The Architect of the World: Eratosthenes

In the third century B.C., the Earth was a philosophical concept. One man dared to make it measurable. Eratosthenes of Cyrene, Chief Librarian of the legendary Library of Alexandria, was the ultimate polymath. Called the Pentathlos for his mastery of science, literature, and history, his mind stretched across the entire breadth of ancient knowledge. Yet, it is his most audacious feat that defines his legacy. With nothing more than simple observation—the angle of a shadow and the sunlight hitting a well—Eratosthenes used geometry to calculate the Earth's circumference with astonishing accuracy. This empirical triumph not only measured our planet but fundamentally created the science of geography. This book tells the complete story of the man who defined the world we inhabit: He created the first global system of latitude and longitude. He compiled the first verifiable chronology of history, dating events from the Trojan War onward. He battled rival thinkers and established the literary canon from his seat of power. The Architect of the World: Eratosthenes is the gripping account of a genius who imposed order on the cosmos, transforming speculative philosophy into systematic science and forever proving that the greatest visionaries are those who dare to measure the impossible.
