In another section of the article, we will deliberate upon the entirety of these principles and evaluate their worthiness in characterizing Iranian architecture. We will strive to study and review Pirnia’s motivations for proposing them, their underlying assumptions, and their tacit implications. In the end we will show that the current order and content of these principles have both internal and external dimensions whose appearance was necessitated by his time. One may argue that such principles are no longer suitable or credible for contemporary Iranian architecture. However reviewing the internal dimension of these principles is a valuable element for identifying and understanding the Iranian architecture in the context of the Iranian culture. In this case, we will be able to reread Pirnia’s principles and use them to serve as vehicle for improvement of research on the history of Iranian architecture and its development.
