One of the literary discussions of the recent century is the examination and correction of literary texts, especially the text of the Shahnama. In recent decades, the corrected editions of the Shahnama by Jules Mohl, the Moscow edition, Mehri Behfar, and Jalal Khaleghi Motlagh have been recognized as the primary and authoritative versions. This research aims to examine several verses from the love story of Zal and Rudabeh based on the aforementioned editions, which have been placed in brackets as a sign of doubt regarding their authenticity, by presenting evidence. This research has been written based on library studies and the mentioned manuscripts using a descriptive-analytical method. The purpose of this research is to become acquainted with the form and foundation of the story, the culture and customs of ancient Iran's heroic and popular traditions, and to preserve the authenticity and details in the verses of the Shahnama—this masterpiece of Persian literature and the guardian of Iran's national identity—which have not been recorded in this correction for whatever reason. The findings of the research, relying on the Ibrahim Sultan Shahnama manuscript, consist of citing and analyzing the doubtful or interpolated verses from a structuralist perspective, examining the socio-cultural context or social tradition of the mentioned verses, becoming acquainted with popular and heroic culture, and the etymology and geography of the story's evolution, which shows that it can be effective in understanding the form and origin of the story and the omitted or interpolated verses.
