Islamic geometric patterns, its history and design methodology

Architectural ornament, Islamic geometric design, girih, polygons in contact, polygonal technique. Abstract. This article deals with the art of geometric ornaments, widely spread in the whole Islamic world. This art appeared at the beginning of the 11th century in Khorasan and Transoxania, rapidly developed in the next two centuries until the Mongol invasion, transferred from here to Damascus, Cairo and further to the Maghreb countries, and then flourished again in the Timurid Empire, when multi-color solutions were added to complicated geometry of star polygons. We consider various principles for constructing these patterns, with special attention to so called “polygonal technique”.
