The popes of the Middle Ages often gave precious liturgical textiles to religious institutions inside and outside Rome. These donations led to a new contextualization of textile gifts, tied to bearers, space, and action, and served to establish a culture of delegated representation, political loyalty, and memoria geared to the Roman papacy. The donated textiles originated from the stock of the papal treasure. Characteristic of it was its heterogeneity and internationality in terms of material, production techniques, origins and image programs, because the precious luxury goods came from major textile centers in Europe, the Mediterranean, Byzantium and Central Asia. This topic is discussed in this book starting from donations by Pope Boniface VIII. (1294-1303) liturgical vestments studied in the treasure of the Cathedral of Anagni (Lazio). The total of nine textile objects are documented and cataloged. On the other hand, they and other papal textiles of the late Middle Ages are contextualized in terms of their function as media of papal representation (before donation), as a gift (at the moment of donation) and as a memory bearer (after donation).
