Researching about a poet whose life is not well known is not an easy task, especially because among the small number of researches that have been conducted, differences and sometimes contradictions are found, which span his life from the Samanids to the Ghaznavids and his religious tendencies from the praise of the Abbasid caliphs to the fourteen Infallibles. Apparently, researchers such as Brown, Ethe, Ripka, Mirzeov, Nafisi, Eqbal Ashtiani, Safa, Riahi, Derakhshan and others who researched about Kisai, were all influenced by Aufi in Lubab ul-Albab and the incorrect reading of the first verse of Lamiyah poem and they have not accepted the simultaneity of him and Rudaki, but if we interpret Kisai's life with a new interpretation of this verse, many of the contradictions in his life will disappear. The simultaneity of Roudaki and Kisai, the praise of Utbi by Kisai, the writing of the poem Manqebat after the poet turned fifty, Kisai and Mahmoud Ghaznavi not meeting, the fading of the poetic correspondence between Nasser Khosrow and Kisai, and perhaps the attribution of an ode to Kisai, which was written after the famous poem of Rudaki; are all among the achievements that this reading of Kisai’s poetry gives. The position of Kisai Marvazi and his pioneering role in Persian literature and the ambiguities and contradictions that can be seen in his life determine the importance and necessity of this research, which the author seeks to highlight some uncertainties about the life and poetry of Kisai and by referring to some personalities and poems of him and his contemporaries andgive new results in this regard.
