Decoding geometry, proportions and its relationship with aesthetics in traditional Iranian architecture

Certain proportions can be observed in creation and design of nature various forms. These proportions are geometrical relationships that are immaterial in origin and follow the spiritual and supernatural principles of their subject sacredness and have symbolic language and spiritual characteristics. Geometry was inseparable from other four Pythagorean sciences in traditional world, including geometric relationships, arithmetic (number), music and astronomy. We always need geometry knowledge in order to construct a building from first steps to final steps. Using proportions is particularly important because of creating visual aesthetic in visual and architectural arts, and almost all artworks are based on some form of proportion. This research tries to decode the work and find the aim and true purpose of its creator in responding the hypothesis that architect knowledge of geometry and his creative use facilitates the conversion of concept into space and form in designing process and minimizes concept erosion of process through studying architecture, geometry and existing proportions. The results obtained from library and field studies by descriptive-analytical method show that different proportions have been used in designing plans, sections and architectural patterns of Iranian traditional architecture.
