Islamic patterns. Metropolitan Museum of Art. Dado panel, first half of 15th century; Mamluk, Egypt. Polychrome marble mosaic. The patterns represent god. It is interesting the math that goes into making these patterns, it is not evenly balanced or correct although it appears to tesselate. This creates the illusion of a static pattern. Because the pattern is not perfectly balanced each artist is allowed to make up his or her solutions to the pattern. The imperfections in the math allow the viewer to be taken on a journey when viewing the wall.
