Abstract
Using modern methods for studying literature does not have a long history in Iran but such methods can be observed in the works of non-Iranian researchers who study Persian literary history. The study of Persian literature and the process of its evolution was considered by non-Iranian researchers from the beginning. Therefore, literary works of Shebly Noamany, Edward Brown and Yan Reepka are considerable because they propose three different views in the study of Persian literature history and its development process: Shebly Noamany’s eastern view, Edward Brown’s western view and Yan Reepka’s realistic view. In addition, topics such as addressee recognition, criticism of trandition and realism, which produced new attitudes in Persian literature are obviously seen in the works of these researchers. In this article, the mentioned topics are studied and the roots of similarities and differences, between the three researchers are investigated. Also, some grounds of modernism in literature are analyzed.
