Symbols and Signs in Islamic Architecture

Although Islam gives function and not form, but Islam as a context has effects on forms and ornaments in some ways. The great role of geometry in Islamic architecture due to restriction of using natural figures is an example. In this research, the application of Islamic geometrical patterns (IGPs), and suitability of their usage over architectural elements is studied. For this purpose, evolution of IGPs through history has been studied, while regional diversities are also taken into account.
