![]() The water falls off the edge of the aqueduct and over the waterwheel in an impossible infinite cycle in his notes on the picture, Escher points out that some water must be periodically added to this perpetual motion machine to compensate for evaporation. The second left-hand turn is supported by pillars from the first, while the other two corners are supported by a tower of pillars that begins at the waterwheel. The viewer is also looking across the scene diagonally from the lower right, which means that from the viewer's perspective the two left-hand turns are directly in line with each other, while the waterwheel, the forward turn and the end of the aqueduct are all in line. The viewer looks down at the scene diagonally, which means that from the viewer's perspective the aqueduct appears to be slanted upward. The aqueduct turns sharply three times, first to the left, then to the right, and finally to the left again. The walls of the aqueduct step downward, suggesting that it slopes downhill. The aqueduct begins at the waterwheel and flows behind it. The image depicts a watermill with an elevated aqueduct and waterwheel as the main feature. A Penrose triangle is an impossible object designed by Oscar Reutersvärd in 1934, and found independently by Roger Penrose in 1958. The watercourse supplying the waterfall (its aqueduct or leat) has the structure of two Penrose triangles. While most two-dimensional artists use relative proportions to create an illusion of depth, Escher here and elsewhere uses conflicting proportions to create a visual paradox. It shows a perpetual motion machine where water from the base of a waterfall appears to run downhill along the water path before reaching the top of the waterfall. Waterfall ( Dutch: Waterval) is a lithograph by the Dutch artist M. Finally, color your design with markers, colored pencils or crayons.Lithograph print by M. (Remember that whatever details you add to one shape, will need to be added to EVERY shape! Keep your details simple.)ĩ. Trace over your pencil lines with a Sharpie and add details to each shape to help others recognize what you “saw” in it. Repeat this step until your whole paper is covered and there are no gaps or spaces.Ĩ. There shouldn’t be any gaps or overlapping. Now, pick up your tile and place it next to your traced design, as if it were a piece fitting into a jigsaw puzzle. (I use 12″x18″ paper when I do this with 6th graders.)Ħ. Place your tile on the center of a 9″x12″ paper and carefully trace around it. Lightly sketch your idea onto your tile…. Turn your newly created shape (we’ll call this your “tile”) in different directions and use your imagination to see if it “looks like” anything. (For older students, you can make this project more challenging by having them repeat this step on an adjacent side of their card, as in the sample project above.)Ĥ. ![]() ![]() If you include a corner in your cut, it makes it easier to line the shape up on the opposite side. Now, tape the shape so that it is exactly across from the spot you cut it from. (The lines on your index card will show you if you’ve flipped or turned it!)ģ. Next, cut a shape from one side of your 3″x3′ card, and slide it to the opposite side of the card, without flipping it over or turning it. Polygon – a shape with three or more sidesĢ. Tessellation – a pattern made with polygons that completely fills a space with no gaps, spaces or overlaps. Escher – a Dutch artist (1898-1972) who is best known for his mathematically inspired drawings and prints which displayed great realism, while at the same time showing impossible perspective, eye trickery and metamorphosis.
