Paul reigned from 1464 until his death in 1471. I think this little excerpt from Wikipedia pretty much stands on its own:

After Paul II's death, one of his successors suggested that he should be called Maria Pietissima, "Our Lady of Pity", because he was inclined to break into tears at times of crisis ^{[verification needed]}. However, some commentators have suggested that the nickname was rather due to Paul II's propensity to enjoy dressing up in sumptuous ecclesiastical finery. He was described as "a collector of statuary, jewelry, and (it was said) handsome youths" ^{[verification needed]}, though rumours of homosexuality may have been introduced by critics to undermine his reputation.
