Vitruvius

Marcus Vitruvius Pollio was a Roman architect and military engineer of the first century BC. What little is known of him comes mostly from his own book. He served under Julius Caesar, apparently as an engineer in charge of artillery and siege machines, and later worked for Augustus, whose sister Octavia helped secure him a pension. He designed a basilica at Fano, which he describes, though it does not survive. In old age he wrote De Architectura, the Ten Books on Architecture, dedicated to Augustus and probably completed between about 30 and 15 BC. It covers the education of the architect, town planning, building materials, temples and the classical orders, public buildings, houses, decoration, water supply, astronomy and sundials, and machines. Vitruvius taught that good buildings must have durability, convenience and beauty, and that their proportions should reflect those of the human body. Copies of the book survived through the Middle Ages, and its rediscovery in the fifteenth century made it the guide of Renaissance architects; Leonardo da Vinci's drawing of Vitruvian Man illustrates his account of human proportion.

Vitruvius is also an author in the library: author page and works.
