February 1468, when Rome was rife with political intrigue fomented by the Roman barons and the neighboring princes, Paul II arrested Platina and other members of the Academy on charges of irreligion, immorality, and an alleged conspiracy to assassinate the Pope. The prisoners were interrogated under torture and eventually released. After his release on 7 July 1469, Platina expected to be again in the employ of Paul II, who, however, declined his services. Platina threatened vengeance and executed his threat, when at the suggestion of Pope Sixtus IV he later wrote his Vitæ Pontificum Platinæ historici liber de vita Christi ac omnium pontificum qui hactenus ducenti fuere et XX (1479). Not unaccountably, Platina set forth an unfavorable delineation of the character of Paul II. Among other things, Platina reported that Pius II suggested Barbo should have been called Maria Pietissima, as "when he could not obtain what he aimed at by praying, entreating, and requesting, he would join tears to his petitions to make them the sooner believed." Some historians have suggested the nickname may also have been a possible allusion to a perceived lack of masculinity, reflecting possible homosexuality. Platina also paints his enemy as cruel, and an archenemy of science. For centuries it influenced historical opinions until critical research proved otherwise. Though Platina's writing after the conflict would tarnish the legacy of Paul II, the conflict would prove to have a greater effect on the intellectual environment of Rome. Peter Partner explains, "Probably its most important result was to convince men of letters that cultural conformity would be enforced in Rome." More tangibly, after the crackdown of Paul II, the Roman Academy took on a more religious flavour, turning in part to theology as a means of legitimizing its pursuits. Final years Pope Paul rejected George of Poděbrady (King George of Bohemia) because he upheld the conventions of the Council of Basel in favour of the Utraquists. In August 1465, Paul II summoned George before the Roman tribunal. When the King failed to come, Paul allied himself with the insurgents in Bohemia and released the King's subjects from their oath of allegiance. In December 1466, he pronounced the ban of excommunication and sentence of deposition against George. George's apologist, Gregory of Heimberg, subsequently accused Paul of immorality, a move that resulted in Gregory's own excommunication. Just when the King's goodwill disposed the Pope in favor of reconciliation, Paul
