Quick Summary

On Architecture (De architectura) is a treatise by the Roman architect and engineer Vitruvius, written around 27 BCE. It is considered a foundational text for architects, drawing heavily on Greek architectural theory and experience.1

The treatise covers a wide range of architectural topics, including city planning, building materials, temple design, public and private buildings, hydraulics, and engineering. Vitruvius aimed to preserve classical traditions in architecture, though Roman architecture soon evolved to meet the demands of a growing empire.1

Vitruvius's work emphasizes three key principles: commodity (utilitas), firmness (firmitas), and delight (venustas). These principles, concerning functionality, structural stability, and aesthetic appeal, have influenced architectural theory for centuries. The treatise was highly influential during the Renaissance and continues to be studied today.213
