Trompe-l'oeil is a French term meaning "deceive the eye", used to describe art that creates a 3D illusion on flat surfaces.
Trompe-l'oeil is an art technique that employs realistic imagery to create optical illusions, making depicted objects appear three-dimensional. This technique can be traced back to ancient times but gained significant popularity during the Renaissance in Europe. Artists use perspective, shadow, and expert detailing to create these illusions. Often, viewers might believe they're looking at actual objects rather than a flat painted surface. Common subjects include lifelike windows, doors, or objects that appear to jut out from the surface. This technique is not only limited to paintings; it's also used in architecture and interior design to create the illusion of depth or to add decorative elements. The intent is always to challenge the viewer's perception of reality.
