摘要：The examination of liturgical codex 56-23 in Toledo Cathedral Library has revealed the existence of an exceptionally rich text, hitherto overlooked by researchers. This document contains an exhaustive assessment of the economic and military capabilities of the Turks and the Christian powers, as well as a description of their strengths and weaknesses in combat. Through the analysis of its contents and its materiality, on the one hand this article associates the circumstances of its origin and use with the preparations for the crusading project that Pius II organized against the Ottoman Empire in 1458. On the other it contextualizes and interprets this new evidence as one of the numerous crusading treatises that proliferated in humanist Europe after the Ottoman conquest of Constantinople in 1453.
