In a study of the methods of geometrical drawings in Iranian architecture of Islamic period, five stages are suggested in the process of design of residential architecture.

Owing to the establishment of the Safavid state, Iranian society witnessed many changes in the political, social, economic, religious, literary and historiographical spheres. These important changes were significant for the political and religious structure, for the beginning of Safavid rule marked the beginning of a new era in Iranian society, affecting all aspects of the life in Iran.
After the Islamic conquest, there were major changes in the written languages used in Iran. The literary Persian of the Sassanid Period, written in the Pahlavi script, continued in use, particularly among Zoroastrians, but as more and more of the population converted to Islam, the literate among them adopted Arabic as their written language, even as they continued to speak Persian and other Iranian languages. Indeed, as already noted, Iranian intellectuals contributed a great deal to the development of Arabic literature in many fields.
Iranian culture is closely linked to classical Persian poetry, which in turn is related to mysticism. In fact, many poets who composed in Persian were practicing mystics themselves. Between the 12th and the 15th centuries, an illustrious line of poets, including Sana’ei, Omar Khayyam, Attar, Rumi, Hafez, Sa’di and Jami, created poetic masterpieces that transcend their time and place.

Starting at a very young age, Iranians are socialized to follow the unwritten rules of the culture and polite behavior that then become second nature to them. They grow up understanding the main reason why they should do so: As a religious duty to behave with respect and cordiality toward others in order to nurture positive and rewarding relationships. Without these, families and other social networks could not function effectively or promote their members’ interests.
