The day's ride included a visit to Agrippa's Pantheon, now denuded of its bronze roofing and marble exterior. A circular opening in the huge dome admits both light and rain. Leo standing with Lucille by the tomb of Raphael in one of the recesses, for a moment was silent. Then he said, "Lucille, it is impossible to fully appreciate the many and beautiful works of this 'prince of painters.' He was born on Good Friday, 1483, and lived exactly thirty-seven years. He was of slight build, sallow, and had brown eyes. Over nine hundred prints of his works are known. Besides his works in fresco at the Vatican, for a time he had charge of the construction of St. Peter's, and he also painted masterpieces now at Bologna, Dresden, Madrid, Hampton Court, and executed numerous commissions for Leo X.; and Madonnas, holy families, portraits, etc., for others. Raphael stands unrivaled, chiefly in his power to portray lofty sentiments which persons of all nationalities can feel, but few can describe. He also excelled in invention, composition, simplicity and grandeur. For moral force in allegory and history, and for fidelity in portrait, Raphael was unsurpassed. His last and most celebrated oil picture, the transfiguration, unfinished, stood at his head as his body lay in state." Colonel Harris was interested in the restored Triumphal Arch of Titus erected to commemorate the defeat of the Jews A.D. 70, also in the beautiful Arch to Severus. At the end of the Rostra, or Orators' Tribune was the Umbilicus Urbis Romae, or ideal center of Rome and the Roman Empire. True it was that all roads led to Rome. Leo and Lucille visited by moonlight the ruins of the great Colosseum, and the lights and shadows in the huge old stone and brick amphitheater, made it look all the more imposing and picturesque. On the morning of the second day Leo Colonna guided his friends down the Via di Ripetta, stopping at the Mausoleum of Augustus, which in the middle ages was used by the Colonnas as a fortress. Then continuing down the left bank of the Tiber, the Ponte S. Angelo was reached. This ancient bridge of five arches leads directly to the Castello S. Angelo, the citadel of Rome, which originally was a tomb erected by Hadrian for himself and successor. The tomb is 240 feet in diameter, and must have been very beautiful, as it was once encrusted with marble. Statues stood around the margin of the top, and above all a colossal statue of Hadrian himself. Later the Goths, veritable iconoclasts, converted this tomb of the emperors into a fortress, hurling the marble statues down on the besiegers. For centuries this castle-tomb was used as a stronghold by the party in power to maintain their sway over the people. In 1822 Pius IX. refortified the castle. In it was seen the gloomy dungeon where Beatrice Cenci and others were incarcerated.
