A MAMLUK LAND TREATY FOR SULTAN QANSUH AL-GHURI Egypt, dated 919 AH (1513) Arabic manuscript on paper, single folio, a total of 80ll. on the recto and 15ll. more on the verso of black ink free-flowing naskh script, marginal annotations, signatures at the end of the document, an ownership seal between the first and second line, the folio 232cm x 32.5cm. The exceptionally large size of this imperial document underlines its importance as a political document. The calligraphic style and the upward bend of the lines suggest a strong connection to later Ottoman treaties and firman documents in diwani script, which are likely to have derived from these Mamluk predecessors.
