Op Art is often geometrical art that plays tricks on the eyes. It has quite a profound effect on the eyes and is sometimes hard to look at for a period of time. This is because of the intense and excessive stimulation to the eyes and brain. Once dismissed as simply optical illusions, it is now understood that Op Art uses complex color theory and line principals. Op art is done in black and white only and also using certain color combinations because of their relationship to one another produces a certain effect on the eye. These color relationships are simultaneous contrast, successive contrast, and reverse contrast (or assimilation). Using certain color relationships will create the optical illusions such as movement, gyration, hidden images and juxtaposition.

Escher was a Dutch \u00a0draftsman, book illustrator, tapestry designer, and muralist, but his primary work was as a printmaker. Aspiring to be an architect, Escher enrolled in the School for Architecture and Decorative Arts in Haarlem. While studying there from 1919 to 1922, his emphasis shifted from architecture to drawing and printmaking upon the encouragement of his teacher Samuel Jessurun de Mesquita. In 1924 Escher married Jetta Umiker, and the couple settled in Rome to raise a family. They resided in Italy until 1935.<\/p>\n<p style=\"text-align: justify;\">After Escher left Italy in 1935, his interest shifted from landscape to something he described as \u00abmental imagery,\u00bb often based on theoretical premises. This was prompted in part by a second visit in 1936 to the fourteenth-century palace of the Alhambra in Granada, Spain. The lavish tile work adorning the Moorish architecture suggested new directions in the use of color and the flattened patterning of interlocking forms. Replacing the abstract patterns of Moorish tiles with recognizable figures, in the late 1930s Escher developed \u00abthe regular division of the plane.\u00bb The artist also used this concept in creating his Metamorphosis prints. Starting in the 1920s, the idea of \u00abmetamorphosis\u00bb\u2014one shape or object turning into something completely different\u2014became one of Escher&#8217;s favorite themes. After 1935, Escher also increasingly explored complex architectural mazes involving perspectival games and the representation of impossible spaces.<\/p>\n<p><iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/5c33l8D0Bg4\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<p><strong>\u25ca \u00a0The Mathematical Art Of M.C.
