In intertextuality studies, no text is assumed to be self-sufficient and any text serves its intertextual function for the preceding and succeeding texts. This study examines the intertextual relations in Valadnameh by Sultan Valad, Resaleye Sipahsalar by Fereydun-ibn-Ahmad, and Manaqib al-chr('39')Arifin by Shams-al-Din Aflaki drawing on theoretical concepts of Gérard Genette. It was found that Resaleye Sipahsalar and Manaqib al-chr('39')Arifin are under the influence of Valadnameh in terms of structure and content of the stories in explicit, non-explicit and implicit ways. It was also found that though Manaqib al-chr('39')Arifin, compared to Resaleye Sipahsalar, is more extensive in content and includes more unreal and fictional content, it has a higher status in terms of its story telling and literary value.
