a seat in the Great Council. In 1463, Bessarion returned to Venice as the papal legate, tasked with negotiating the republic's participation in a crusade to liberate Constantinople from the Turks. For the duration of this extended sojourn (1463–1464), the cardinal lodged and studied in the Benedictine monastery of San Giorgio Maggiore, and it was to the monastery that he initially destined his Greek codices which were to be consigned after his death. But under the influence of the humanist Paolo Morosini and his cousin Pietro, the Venetian ambassador to Rome, Bessarion annulled the legal act of donation in 1467 with papal consent, citing the difficulty readers would have had in reaching the monastery, located on a separate island. The following year, Bessarion announced instead his intention to bequeath his entire personal library, both the Greek and Latin codices, to the Republic of Venice with immediate effect. On 28 June 1468, Pietro Morosini took legal possession of Bessarion's library in Rome on behalf of the republic. The bequest included the 466 codices which were transported to Venice in crates the next year. To this initial delivery, more codices and incunabula were added following the death of Bessarion in 1472. This second shipment, arranged in 1474 by Federico da Montefeltro, departed from Urbino, where Bessarion had deposited the remainder of his library for safekeeping. It included the books that the cardinal had reserved for himself or had acquired after 1468. Despite the grateful acceptance of the donation by the Venetian government and the commitment to establish a library of public utility, the codices remained crated inside the Doge's Palace, entrusted to the care of the state historian under the direction of the procurators of Saint Mark de supra. Little was done to facilitate access, particularly during the years of the conflict against the Ottomans (1463–1479) when time and resources were directed towards the war effort. In 1485, the need to provide greater space for governmental activities led to the decision to compress the crates into a smaller area of the palace where they were stacked, one atop the other. Access became more difficult and on-site consultation impracticable. Although codices were periodically loaned, primarily to learned members of the Venetian nobility and academics, the requirement to deposit a security was not always enforced. A few of the codices were subsequently discovered in private libraries or even for sale in local book shops.
