Trompe l'oeil — term derived from French meaning "deceive the eye," is a captivating artistic technique often employed in mosaic art.

This form of representation aims to create a realistic illusion that tricks the viewer's perception. Mosaic artists skillfully arrange small, coloured tesserae to mimic three-dimensional objects or scenes on a two-dimensional surface. The meticulous attention to detail and shading techniques used in trompe l'oeil mosaics give the impression of depth and texture, blurring the line between art and reality.
