Proportions in the height components of the four-porch mosques

Proportions can be called a mathematical concept that creates a good relationship between the components of the work in architecture and likewise a sense of order among the parts of a visual composition in the audience. Proportions not only can can make building component arrengment regular but also it can it can create a sense of aesthetics. Traditional Iranian artists and architects have been interested in geometric proportions and divisions due to their hidden relationships, and have used these proportions in their works. The present study is an attempt to find traces of proportions in Iranian mosques as one of the most prominent elements in Islamic architecture, which has explored the height proportions of four-aisled mosques through descriptive, analytical and library and field studies. An attempt has been made to extract a height or a connection pattern between the components of each of the eight mosques so that a hierarchy of height design can be imagined. In the end, by examining the proportions and height patterns, it was found that in 8 analyzed samples, all the elevation elements of the research were obtained from the height of the courtyard facade and the shortest porch of the complex with golden and Islamic-Iranian proportions. In all the studied samples, the shortest porch of the complex with the height of the courtyard facade has proportions close to the Golden Ratio. In Goharshad, Zavareh, Isfahan and Imam Boroujerd mosques, there is a similar pattern in the view of the south porch, so that the height of this porch is almost twice the height of the courtyard view in these four mosques.
