In various sources of Persian poetry stylistics, the stylistic features of pre-constitutional poetry have been examined in a detailed and meticulous manner. But what has not been paid attention to in this area and has definitely been neglected are the fundamental theses and theories of those styles. It seems that the past stylistic evolutions of Persian poetry have been based on a basic rule, and with the change of those rules or stylistic theses, the characteristics of each style have been different and transformed from other styles. In this research, we aim to identify those theses and theories and examine their influence in the stylistic transformations of Persian poetry - of course, in the context of its historical developments.
