Bessarion (; 2 January 1403 – 18 November 1472) was a Byzantine Greek Renaissance humanist, theologian, Catholic cardinal and one of the famed Greek scholars who contributed to the revival of letters in the 15th century. He was educated by Gemistus Pletho in Neoplatonic philosophy and later served as the titular Latin Patriarch of Constantinople. He eventually was named a cardinal and was twice considered for the papacy.
