The Comparison of theMaterials in Styles of Iranian Architecture and its Effect on the Form of the Building before the Islam’s Entry to Iran

Abstract

During the history,different elements have been determined as influential factors affecting the architecture in different areas. The historical events and political alterations as well as religious and economical changes can directly lead to the architecture style. One of the historical countries with rich architectural history that can be increasingly exposed to more alterations is Iran. In general the architecture styles in Iran can be categorised in six groups. These groups can be divided in two periods before and after Islam's emergence in Iran. The Parsi and Parti architecture styles belong to the former period and Razi, Khorasani, Isfahani and Azari were common in the latter period, after Islam. Such alterations brought in a variety of architecture styles, in this country, due to theoretical alterations. Furthermore, some novel architectural styles were resulted from a number of physical conditions which had also effects on the theoretical architecture. The current research intends to put an emphasize on the alterations in materials used in two historical periods of Iran, Achaemenid Empire (550-330 BCE) and The Sassanid Empire (224 CE to 651 CE) resulting in the changes in Iranian architecture. It also aims to explore the differences and the reasons of changes in the materials used for constructions and the influence that these changes had on the architectural style in the above mentioned periods.
