HUMANIST POPE 231
far deeper impression on Nicholas V than did a conspiracy, organized by Porcaro, a demagogue and a shadow of Rienzi, who paid for his Gesaristic dreams and his attempts on the lives of the Pope and the cardinals with death by hanging.
A troubled Conclave followed the death of Nicholas and chose as Pope a Spaniard who had proved his mettle as a diplomat. He took the name of Calixtus III (14551458). He was descended from the powerful and prominent family of the Borgia of Valencia, and had grown up hating Islam. The war against the Turks became his polit- ical program: he sent men and money to Hunyadi, Regent of Hun- gary; and among the men were the Cardinal Legate Carvajal, the Pope's countryman, and St. Juan Capistrano, a fiery preacher.

This noble Siennese, who had known a childhood of poverty, called himself Pius II (1458-1464) , because "Pius" was the adjective coupled with -^Eneas in his beloved Virgil's epic. He was a broad- minded humanist who had manifested the brilliance and richness of a universal mind in writings and addresses. He was known as a charm- ingly libertine story-teller after the manner of Boccaccio, as a defender of the councilar idea, as secretary to an anti-Pope, as a geographer, as the historian of the Council of Basel, and as a diplomat in the Imperial chancellery. When he reached the age of fifty he stripped off a cer-
