The private library of Cardinal Bessarion constitutes the historical nucleus of the Marciana. In addition to liturgical and theological texts for reference, Bessarion's library initially reflected his particular interests in ancient Greek history, Platonic philosophy, and science, especially astronomy. Some of these texts were brought by Bessarion when he arrived in Italy (1438) for the Council of Ferrara-Florence; others were shipped at an unknown later date from the Venetian city of Modone (Methoni), near Mystras where Bessarion had studied under Gemistus Pletho. Among the early codices were works by Cyril of Alexandria, Euclid, Ptolemy, and Strabo, some of which were rare, if not unknown, in Western Europe. Elevated to the cardinalate in 1440, Bessarion enjoyed greater financial resources, and he added notable codices, including the precious tenth-century manuscripts of Alexander of Aphrodisias' works and of Ptolemy's "Almagest" that had once belonged to the library of Pope Boniface VIII.
