![]() You can still find zillij installations in Morocco and other predominantly Islamic countries, on the walls and floors of mosques, homes, public squares, and tombs. This style of mosaic tilework is made from individually hand-chiseled pieces set into a plaster base. In Islam, using tessellations to decorate surfaces and is called zillij. Inside the fortress, walls are adorned with countless colored tiles in geometric formations. It was constructed by the Muslim Moors in the 14th century and became the royal residence and court of Mohammed ibn Yusuf Ben Nasr. One of the most famous examples of Islamic tessellation art is in the Alhambra, a huge palace located in Granada, Spain. ![]() Therefore, they embraced the abstract characteristics of tessellation and used colorful geometric tiles to create non-representational patterns. Grey-white differentiation refers to the appearance of the interface between cerebral and cerebellar white matter and grey matter on brain CT and MRI. This is because many Muslims believe that the creation of living forms is solely God’s doing. Religious Islamic art is typically characterized by the absence of figures and other living beings. Perhaps the most celebrated style of tessellations can be found in Islamic art and architecture. While the Sumerians of 5th and 6th BCE used tiles to decorate their homes and temples, other civilizations around the world adapted tessellations to fit their culture and traditions the Egyptians, Persians, Romans, Greeks, Arabs, Japanese, Chinese, and the Moors all embraced repeating patterns in their decorative arts. Tessellations in Ancient Islamic Art and ArchitectureĬeramic tile tessellations in Marrakech, Morocco (Photo: Wikimedia Commons, (CC BY-SA 3.0)) Now that we’ve covered the basic math of tessellations, read on to learn about how they were used throughout history. Each vertex is surrounded by the same polygons arranged in the same recurring order. Semi-regular tessellations occur when two or more types of regular polygons are arranged in a way that every vertex point is identical. A checkerboard is the simplest example of this: It comprises square tiles in two contrasting colors (usually black and white) that could repeat forever. Regular periodic tiling involves creating a repeating pattern from polygonal shapes, each one meeting vertex to vertex (the point of intersection of three or more bordering tiles). The most common configurations are regular tessellations and semi-regular tessellations. There are many types of tessellations, all of which can be classified as those that repeat, are non-periodic, quasi-periodic, and those that are fractals.

Like the uniform polyhedra there are eight uniform tilings that can be based from the regular hexagonal tiling (or the dual triangular tiling).ĭrawing the tiles colored as red on the original faces, yellow at the original vertices, and blue along the original edges, there are 8 forms, 7 which are topologically distinct. Wythoff constructions from hexagonal and triangular tilings It is also topologically related as a part of sequence of Catalan solids with face configuration Vn.6.6, and also continuing into the hyperbolic plane. Symmetry given assumes all faces are the same color. With identical faces ( face-transitivity) and vertex-transitivity, there are 5 variations. The triangular tiling has Schläfli symbol of topology as the regular tiling (6 triangles around every vertex). Because the internal angle of the equilateral triangle is 60 degrees, six triangles at a point occupy a full 360 degrees. In geometry, the triangular tiling or triangular tessellation is one of the three regular tilings of the Euclidean plane, and is the only such tiling where the constituent shapes are not parallelogons. Vertex-transitive, edge-transitive, face-transitive Regular tiling of the plane Triangular tiling
