For years I have been shown works of art by M.C Escher. We've all seen his image of the never-ending staircase, as well as the images of the intertwining fish. But the image I am going to focus on is his 1958 Belvedere lithograph. If one looks at this picture, the tower looks completely normal, and actually quite beautiful. But then if one looks closely, one would notice that the pillars of the tower do not connect in the right places. Actually, the tower would not be capable to stand correctly if the pillars were connected the way they are in the picture. This illusion is an example of both top-down and bottom-up processing. Our top-down processing convinces us that this tower is just an image of a beautiful tower. The reason for this is that we expect the tower to be put together the right way since it looks like a normal tower. But then we start to look at the actual pieces of this tower, and see that it is not put together correctly. This forming a perception based off of parts is our bottom-up processing. We form a perception based off of the individual parts of the image. And from examining the parts, we then come to perceive the image a certain way. And if one looks at the individual parts of the tower, one realizes that it is a nonsensical tower. And that is why M.C Escher is such an illusionary genius. He is able to create images that look perfectly normal upon first glance. For example, when I examined the image further, I realized it does not make sense. Even after realizing the image does not make sense, for some reason it still looked like a normal tower. M.C Escher was truly one of a kind!
