Trompe-l'œil (French for deceive the eye, pronounced [tʁɔ̃p lœj]), which can also be spelled without the hyphen and ligature in English as trompe l'oeil, is an art technique that uses realistic imagery to create the optical illusion that depicted objects exist in three dimensions. Forced perspective is a comparable illusion in architecture.
History in paintingEdit
Though the phrase originates in the Baroque period, when it refers to perspectival illusionism, trompe-l'œil dates much further back. It was (and is) often employed in murals. Instances from Greek and Roman times are known, for instance in Pompeii. A typical trompe-l'œil mural might depict a window, door, or hallway, intended to suggest a larger room.
A version of an oft-told ancient Greek story concerns a contest between two renowned painters. Zeuxis (born around 464 BC) produced a still life painting so convincing that birds flew down to peck at the painted grapes. A rival, Parrhasius, asked Zeuxis to judge one of his paintings that was behind a pair of tattered curtains in his study. Parrhasius asked Zeuxis to pull back the curtains, but when Zeuxis tried, he could not, as the curtains were Parrhasius's painting—making Parrhasius the winner.
With the superior understanding of perspective drawing achieved in the Renaissance, Italian painters of the late Quattrocento such as Andrea Mantegna (1431–1506) and Melozzo da Forlì (1438–1494), began painting illusionistic ceiling paintings, generally in fresco, that employed perspective and techniques such as foreshortening to create the impression of greater space for the viewer below. This type of trompe l'œil illusionism as specifically applied to ceiling paintings is known as di sotto in sù, meaning "from below, upward" in Italian.
The elements above the viewer are rendered as if viewed from true vanishing point perspective. Well-known examples are the Camera degli Sposi in Mantua and Antonio da Correggio's (1489–1534) Assumption of the Virgin in the Duomo of Parma. Similarly, Vittorio Carpaccio (1460–1525) and Jacopo de' Barbari (c. 1440 – before 1516) added small trompe-l'œil features to their paintings, playfully exploring the boundary between image and reality. For example, a fly might appear to be sitting on the painting's frame, or a curtain might appear to partly conceal the painting, a piece of paper might appear to be attached to a board, or a person might appear to be climbing out of the painting altogether—all in reference to the contest of Zeuxis and Parrhasius. In a 1964 seminar, the psychoanalyst and theorist Jacques Lacan (1901–1981) observed that the myth of the two painters reveals an interesting aspect of human cognition. While animals are attracted to superficial appearances, humans are enticed by the idea of things that are hidden.
Perspective theories in the 17th century allowed a more fully integrated approach to architectural illusion, which when used by painters to "open up" the space of a wall or ceiling is known as quadratura. Examples include Pietro da Cortona's Allegory of Divine Providence in the Palazzo Barberini and Andrea Pozzo's Apotheosis of St Ignatius  on the ceiling of the Roman church of Sant'Ignazio.
The mannerist and Baroque style interiors of Jesuit churches in the 16th and 17th century often included such trompe-l'œil ceiling paintings, which optically "open" the ceiling or dome to the heavens with a depiction of Jesus', Mary's, or a saint's ascension or assumption. An example of a perfect architectural trompe-l'œil is the illusionistic dome in the Jesuit church, Vienna, by Andrea Pozzo, which is only slightly curved but gives the impression of true architecture.
A fanciful form of architectural trompe-l'œil, quodlibet, features realistically rendered paintings of such items as paper-knives, playing-cards, ribbons, and scissors, apparently accidentally left lying around.
Trompe-l'œil can also be found painted on tables and other items of furniture, on which, for example, a deck of playing cards might appear to be sitting on the table. A particularly impressive example can be seen at Chatsworth House in Derbyshire, where one of the internal doors appears to have a violin and bow suspended from it, in a trompe l'œil painted around 1723 by Jan van der Vaart.
The American 19th-century still-life painter William Harnett specialized in trompe-l'œil. In the 20th century, from the 1960s on, the American Richard Haas and many others painted large trompe-l'œil murals on the sides of city buildings, and from beginning of the 1980s when German Artist Rainer Maria Latzke began to combine classical fresco art with contemporary content trompe-l'œil became increasingly popular for interior murals. The Spanish painter Salvador Dalí utilized the technique for a number of his paintings.
