For this purpose, in this study, the pictorial and structural features of the manuscripts of the anthology of Eskandar Sultan in the Galouste Gulbenkian Foundation of Lisbon and the anthology of the poems of Ibrahim Sultan in the Berlin State Museum have been studied. The purpose of this basic research, which has been done by using descriptive, analytical methods with a comparative approach, is to find the visual and structural relationship between the versions of these two periods and to answer this question: Considering the temporal, spatial and cultural similarity of Shiraz school during the reign of Eskandar Sultan and Ibrahim Sultan, what are the commonalities and differences between the visual and structural features of the anthology of these two periods? Data collection was done using library resources, documents and virtual databases. The research results show that although many similarities such as scene selection, realistic approach, tabulation and annotation can be seen in the anthology of these two eras, but the multiplicity, variety and quality of visual elements have decreased in the time of Ibrahim Sultan and composition has played a different role and less prosperous effects than in the previous era.
