The Trompe-l’œil Technique: The Art of Optical Illusion

Tromp l'oeil is an artistic technique that involves images treated in a realistic manner in order to create the optical illusion of three-dimensional space on a two-dimensional surface such as the support of an easel painting or a mural.

Although the term originated in the Baroque period, when it was used to refer to the illusion of perspective, it can be found even before this period in both ancient Greece and ancient Rome, in the murals of Pompeii. A typical tromp l'oeil mural may represent: either a window, a door, or a hallway, intended to suggest a larger room.

Through a superior understanding of the laws of perspective, in the Renaissance Italian artists of the Quatrocento, such as Andrea Mantegna and Melozzo da Forli, who began with fresco paintings, in which they tried to give the illusion of a larger space. The technique by which the viewer below perceived the painting on the ceiling as an opening with an extended space was called " di sotto in su" (Italian lb.) meaning from below upwards.

Similar tromp l'oeil works were also experimented with by artists Vittorio Carpaccio and Jacopo de' Barbari. For example, a simple fly that has settled on the edge of a painted picture frame, or a curtain that half hides a painting, or a piece of paper that appears glued to a blackboard, or even a person emerging from a painting.

Perspective theories that began in the 17th century brought a different approach to perspective that was much more architecturally framed. This was also known as " quadratura " (Italian), which means framing.

A very telling example in this sense is the work of Pietro da Cortona - " Allegory of Divine Providence".

Tromp l'oeil can also appear painted on various pieces of furniture, and later in the 19th century, the American artist whose art was dominated by still lifes, William Harnett, was particularly concerned with the tromp l'oeil technique.

In the 20th century, in the 1960s, the American artist Richard Haas and many other artists executed various murals in the tromp l'oeil technique, on various walls of buildings, as well as in various interiors.

Other artists who worked in the tromp l'oeil technique were: Salvador Dali, Rene Magritte, Henry Alexander, John Haberle, Walter Godman, and many other contemporaries.

Today, murals with tromp l' oeil effects are increasingly used as part of the interior design of private homes but also in other public spaces, even furniture.
