Among the more important museums and picture galleries are the splendid Vatican, at which we have glanced, the Capitol Museum, the Palazzo del Senatore, with works by Velazquez, Van Dyck, Titian, and other masters, the National Museum, the Villa Borghese, the Dorian Palace, and the Kircheriano. The art annals of the Rome of Christian times are of supreme interest. The greatest of the painters who came to study in Rome was Velazquez, who was offered the hospitality of Cardinal Barberini in the Vatican. He stayed, however, in a quieter lodging, at the Villa Medici, and afterwards in the house of the Spanish ambassador. Velazquez paid a second visit to Rome in 1649, where he met Poussin, and Salvator Rosa. To Rosa he remarked, "It is Titian that bears the palm." The Spanish painter was made a member of the Roman Academy; and at this time he painted the portrait of Innocent X., which occupies a position of honour in the Dorian Palace. Reynolds described this as "the finest piece of portrait-painting in Rome." Velazquez' portrait of himself is in the Capitoline Museum in the city. The art records of Rome are so many that I cannot attempt to refer to more than a small number of them. Literary associations, too, crowd into the mind as we walk the lava-paved streets of the glowing capital. Goethe sojourned long in Rome, and wrote many pages of his impressions. In 1787 he writes of the amazing loveliness of a walk through the historic streets by moonlight, of the solemnity of the Coliseum by night, and the grandeur of the portico of St Peter's. He praises the climate in spring, the delight of long sunny days, with noons "almost too warm"; and the sky "like a bright blue taffeta in the sunshine." In the Capitoline Museum he admired the nude "Venus" as one of the finest statues in Rome. "My imagination, my memory," he writes, "is storing itself full with endlessly beautiful subjects.... I am in the land of the arts." Full of rapture are the letters of Shelley from Rome: "Since I last wrote to you," he says to Peacock, "I have seen the ruins of Rome, the Vatican, St Peter's, and all the miracles of ancient and modern art contained in that majestic city. The impression of it exceeds anything I have ever experienced in my travels.... We visited the Forum, and the ruins of the Coliseum every day. The Coliseum is unlike any work of human hands I ever saw before. It is of enormous height and circuit, and the arches, built of massy stones, are piled on one another, and jut into the blue air, shattered into the forms of overhanging rocks."
