The Papacy we left at the end of the sixteenth century in the full flood of revival. The Popes were swept on by the tide. The bold and successful front opposed to the enemy was supplemented by discipline within. Heresy was traced and tracked. Inquisitors roamed about, spying what they might; they frightened the learned from publishing, printers from printing, and almost all from freedom of talk and thought. Thus traitors were rooted out. And at the same time faithful soldiers of the Church were trained and educated. Seminaries for priests of divers nations were founded in Rome; Jesuit schools were helped everywhere. Sixtus V (Felice Peretti), 1585-90, was a Pope worthy of the great period. He entertained a plan to reconquer Egypt, and make the Mediterranean and Red Seas a high-road for armies and navies that should break up the Ottoman power. He attacked the banditti of the Papal State, as his predecessors had attacked the barons, and, for a time at least, suppressed them. He was a great builder; he completed the dome of St. Peter's, set up the Egyptian obelisk in the _piazza_ before the cathedral, substituted statues of St. Peter and St. Paul in place of Trajan and Marcus Aurelius on the tops of the two great bronze columns that adorn the Foro Trajano and the Piazza Colonna. He brought fresh water, named after him Acqua Felice, into the city from over twenty miles away, and gave Rome an aspect worthy of the capital of the Latin world. He fixed seventy for the number of cardinals; he revised the Vulgate; and pondered many great designs, for which, as he said, his strength would have been inadequate, even had he lived.
