Explanation the meaningful relation between ornamental pattern and structural in tower temples in khorasan (Qaznavi and Saljoughi era)

The relation between texture, pattern and massing is a fundamental question in architecture. Classical architecture, as Leon Battista Alberti states in De Re Ae dificatoria, Book VI, Chapter 2, is developed through massing and structure first; texture is added afterwards to give the bold massing and structure beauty [Rietherand and Baerlecken, 2008: 2]. This hierarchy has of course been challenged throughout architecture history.

In the literature review, most researchers have done focus on pattern of Islamic ornamentation based on the interior vision and exterior pattern effect is not considering by researchers. This paper will provide a different thinking of the relationship of massing and texture in Persian Architecture based on tower temple in Khorasan that built in Qaznavi and Saljoughi era.
After that, we consider the role of the ornamental pattern on shaping building structure. Since this research were done based on mathematic and geometric systems, the main research way in this paper is logical deduction.
One of the main important result of this research is the meaningful relationship between ornamental pattern and structural in Iranian Architecture.
