Answer
The architectural works of the ancient Roman architect and engineer Vitruvius were rediscovered and brought to light by the Italian humanist and scholar Poggio Bracciolini. Poggio's discovery in 1414 played a pivotal role in the revival of classical architecture during the Renaissance period. Vitruvius's treatise "De Architectura" became a foundational text for architects, influencing the design and construction of many iconic Renaissance buildings.
