The Ancient Engineers by L. Sprague de Camp

A lively, readable survey of the technological achievements of ancient civilizations that explains how builders and inventors solved practical problems with bridges, roads, aqueducts, dams, irrigation, machines, surveying instruments, siege engines and architectural innovations; it outlines the engineering principles behind those devices, places them in their chronological and cultural contexts, dispels misconceptions, and traces the evolution and transmission of technical knowledge from Mesopotamia and Egypt through Greece and Rome to India, China and the medieval Islamic world, showing how ancient practical ingenuity laid foundations for later developments.
