Answer
Michelangelo, the renowned Renaissance architect, drew inspiration from the writings of the Roman architect Vitruvius. Vitruvius's treatise on architecture, "De Architectura," provided Michelangelo with a framework for understanding classical architectural principles, such as proportion, symmetry, and the use of orders. Michelangelo's designs, including the dome of St. Peter's Basilica, reflect the influence of Vitruvius's ideas, showcasing a harmonious blend of classical and Renaissance aesthetics.
