Talk in German about Trompe-l'œil as a form of visual deception.

As is known, Italian Renaissance artists discovered central perspective thus finding a method to construct a visually convincing impression of the depth of space in painting. Famous theorist Leon Battista Alberti described a painting as a «window», which opens to a painted world. This revolutionary concept immediately implied the reverse: what if a painting is not an open window, but an impenetrable surface, in front of which everything painted is situated? For centuries this idea produced very different kinds of visual deception (trompe-l’oeils).
