Abstract:

Geometric decorations have been used in almost every period of history. In his works of Islam, the geographical area developed in the Emevi, Abbasi, Karahanlı, Gazneli and the Great Selçuklu periods, and depending on the type of material used, it appeared in different forms in this area. The composition forms applied in the Iranian region, especially with rubber materials, were applied more with stone materials when they moved to Anadolu. In addition to the stone, wood and geometric motifs in China have continued to be enriched with important examples. The geometric compositions, which were applied with almost every material in every area of the basement, along with plant, text and figure compositions, continued its existence uninterrupted throughout the Selçuklu, Bejliks and Ottoman epochs. The geometric patterns used in Islamic works consist of different geometric forms, such as square, five-gen, six-gen, seven-gen, eight-gen, nine-gen, ongen, six-gen, twenty-quarters, apartments. As there was no inventory work on our subject, from the data obtained from some source books and web pages, 39 different geometric patterns of a total of 223 works found in some museums and libraries in Morocco, India, Iran, Spain, Egypt, Uzbekistan, Syria, Turkey and Britain were studied in 13 groups. Due to the limits of our study, chronology, geographical location or material differences that are used are not observed, only six-gen-based geometric patterns have been studied in terms of shape. We have created a new six-cylindrical grid system to draw these patterns more practically. This is the new approach mentioned. Also, patterns that are similar to each other or can be accepted variation are grouped, the drawings of patterns are displayed through the new network that has been revealed. Due to the limits of the article, no detailed pattern analysis was made. Only the patterns are shown in the form of placement on the grid.
