was influenced by the Mannerist painter. For Dalí the Arcimboldo effect was a form of self concealment as well as this exhibitionist painter seemed, all throughout his life of constant posturing, to hide his real self behind the gaudy externals of his behaviour. Larvatus prodeo, "I wear a mask," he could have said with Descartes and he used this quotation from the French philosopher for the epigraph of his novel Hidden Faces. Probably his most famous "hidden face" is Voltaire in his oil painting: "Slave Market with the Disappearing Bust of Voltaire". Other Surrealist painters rediscovered the technique of hidden faces in the first part of 20th century: Max Ernst René Magritte Istvan Orosz tries to combine the technique of anamorphosis with the hidden faces. Anamorphosis is used for those works of art that were made as distorted and unrecognizable through clever geometrical constructions. But when viewed from a certain point, or through a reflecting object placed upon it, the hidden image appears in its true shape, that is, it goes through retransformation. Orosz made experiments with anamorphoses not only in resurrecting the old technique but to improve and develop it. Instead of having a meaningless distorted image, his intent is to bring sense to the basic anamorphic picture, giving it meaning in itself with its second reading being revealed by viewing it from a different viewpoint such as looking at it through a special mirror. The ambiguous layers coming up by this approach make use of the connection or contrast of the two images within the same picture being independent from each other. There are many other contemporary works using hidden faces: Shigeo Fukuda Octavio Ocampo Sandro del Prete See also Anamorphosis Anthropomorphism Face perception Hide-and-Seek (painting) Rubin vase Utisz Literature The pioneering study on the matter is an academic dissertation, unpublished to this day: Anita Joplin, The Anthropomorphic Landscape: A Study in 16th Century Imagery (unpublished thesis, Reed College), 1974.
