This paper is a survey of previous studies on ‘Aṭṭār (Farīd al-Dīn ‘Aṭṭār, d. 1221?), one of the greatest Persian poets, and also aims to present the reasons for my study on ‘Aṭṭār. Many researchers have already studied ‘Aṭṭār. However, each researcher employs various research methods of approach to ‘Aṭṭār, and there is a diversity among them. For instance, Hellmut Ritter employs a didactic method of approach to ‘Aṭṭār in his treatise, and on the other hand, Dick Davis employs a structural method. Even a didactic method can be divided into two positions, historicism and text-centrism, and the same can be said of a structural method. Differing from didactic and structural methods, there are two other methods, which relate to symbol evaluation and reception history. These can reinforce didactic and structural methods. Although a researcher may favour one method of approach to ‘Aṭṭār over other methods, that does not mean they adopt just one method. Many researchers use other methods to support the logic of their treatises Like my predecessors, I plan to adopt one main research method while using other methods to support my study on ‘Aṭṭār.
