There is also a point of 2-fold rotation on each fish's contour. Joining these points on the same fish in cyclic order will outline an equilateral triangle. Each of these points marks a location at which more than two fish meet. Ignoring color differences, there are centers of 6-fold rotation at the upper tip of each fish's right wing. There are centers of 3-fold rotation at the upper tip of each flying fish's left wing and the left tip of its tail. This tessellation has both translational and rotational symmetry. It is interesting to see basic geometric ideas and drawing techniques which Escher did by creating tessellations. It is interesting to study his art of tessellations and compare his tessellation to geometric forms. ![]() Related to this topic is the work of the artist M.C. If you need a detailed description of that principles, push the button. There are basically 4 ways of how a diagram can be “mapped onto” itself, namely, by translation, rotation, reflection and glide reflection.We will discover in the following diagrams, how this design can be “mapped onto” itself, which is the fundamental idea of how tessellations work. To illustrate the principles behind a simple tessellation pattern, a tiling consisting of equilateral triangles of degree 6 at each vertex will be used as an example to illustrate these principles. There are certain principles of tessellations. There are exactly three regular tessellations composed of regular polygons symmetrically tiling the plane. Tessellations however, do not need the use of regular polygons, below is an example. By definition, tilings require the use of regular polygons put together such that it completely covers the plane without overlapping or leaving gaps. There is a difference between a tiling and a tessellation. In other words a tiling of regular polygons (in two dimensions), polyhedra (three dimensions), or polytopes (n dimensions) is called a tessellation. 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.What are tessellations? It is an arrangement of closed shapes that completely cover the plane without overlapping or leaving gaps. 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. 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.

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.
