	In 17th and 18th century Britain, one of the applications of trompe l’oeil was for reasons of aesthetics, economy and practicality: the use of polished plaster on walls and columns gave a highly-realistic impression of marble or travertine, creating an illusion of depth and texture, without requiring the stonemason’s craft – and at a fraction of the cost. Polished plaster was first used by the ancient Egyptians and extensively in Venetian palaces of the Renaissance and Baroque periods. It is still in use today throughout the world.

−	Artists throughout history have used trompe l’oeil. It was used to trick the observer in believing that what is depicted on a two-dimensional surface is actually three dimensional. Many cities have striking modern murals that achieve this effect, although the ‘reality’ may depend on where the viewer stands.	+	Artists throughout history have used trompe l’oeil.

	Architects may use trompe l’oeil to correct a natural phenomenon. The ancient Greeks, for example, added entasis to the columns of the Parthenon and other temples to correct the natural ‘appearance’ (to the naked eye) of columns buckling or bowing – which was considered an illusion of weakness. By splaying the columns almost imperceptibly inwards at their upper reaches (in other words decreasing the column diameter) the result is a column with convex sides, that gives, paradoxically, an illusion of straightness and so of ‘solidity’ and ‘strength’.

−	Later, in the Baroque period, the 17th century architect and sculptor ~~Gianlorenzo~~ Bernini who designed the colonnades on either side of St Peter’s Square, Rome, created a design of immense proportions (1656-1667). To give the visitor the effect of an embrace in the “maternal arms of the Mother Church”, the colonnades on either side of the square are splayed outwards in the direction of the basilica. On approaching the basilica, the visitor does not perceive the usual natural perspective of lines converging to a vanishing point. Instead, the diverging colonnades look to be parallel, an optical illusion that makes the basilica appear closer to the viewer than it actually is. Leaving the basilica, the effect is reversed as the exaggerated perspective of the converging colonnades results in significant foreshortening.	+	Later, in the Baroque period, the 17th century architect and sculptor Gian Lorenzo Bernini who designed the colonnades on either side of St Peter’s Square, Rome, created a design of immense proportions (1656-1667).
