Which technique allowed Renaissance painters to depict depth on a flat surface?

• A. Linear perspective
• B. Chiaroscuro
• C. Sfumato
• D. Fresco

Answer: (A)

Think about how Renaissance artists turned flat surfaces into convincing space. The technique that achieves depth on a two-dimensional plane is linear perspective. It uses a horizon line at the viewer’s eye level and converging lines, called orthogonals, that recede toward a single vanishing point. By making parallel lines converge and by objects diminishing in size with distance, the scene reads as three-dimensional—floor, walls, and architecture appear to recede realistically into space. This system gives a coherent spatial framework for figures and structures to inhabit, guiding the viewer’s eye into the illusion of depth.

Chiaroscuro focuses on modeling form with light and shadow to suggest volume, not a consistent method for creating depth on the plane. Sfumato blends tones to create soft, smoky transitions, which smooths edges but doesn’t establish a perspective grid. Fresco refers to painting on wet plaster as a medium, not a specific technique for depicting depth.
