In the cloister are some frescoes of the universal Domenichino. I like the Convent of San Onofrio. To Santa Maria in Trastevere, a very fine church; splendid ceiling with a Domenichino in the middle. Immense granite columns of various orders taken from God knows what temples, and mosaic floor rich to a degree. Large pieces of porphyry and verd antique eternally trodden by the Trasteverine mob, and never even cleaned. It is a basilica, and at the end is an ancient stone chair, which, was evidently the old justice-seat, though they of the Church do not know it. April 14th, 1830 {p.329} Set off early to make up an arrear of churches. First to Santa Maria sopra Minerva, and lit upon the funeral of a cardinal (Bertazzoli), which I was obliged to see instead of Michael Angelo's Christ. All the cardinals attended; the church hung with black and gold; guards, tapers, mob, &c. Then to the SS. Apostoli, Araceli (built where the Citadel stood, and is a corruption of Arx, but with a legend); a curious church enough, with some fine frescoes of Pintoriccio, and the Chapel of the Virgin with hundreds of ex voto's hang round it, almost all wretched daubs of pictures, and principally representing accidents in gigs, carriages, or carts, broken heads or limbs. To Santa Anastasia, Santa Maria in Cosmedin, Santa Sabina. Santa Maria in Cosmedin, or the Bocca della Verità, built in and on the ruins of an old temple (di Pudicizia), is one of the best worth seeing in Rome; the columns, if freed from the modern church, would present as perfect a front as the temples in the Forum. To Monte Aventino to see the view of Rome and the Chapel of the Order of Malta, where Cardinal Zurla as Grand Prior has a most agreeable residence. The garden contains immense orange-trees and a very large palm. To San Gregorio to see the famous rival frescoes of Guido and Domenichino, which are much impaired. I began by liking Guido's and ended by liking the other best. The view of the Palatine from this convent is magnificent. To San Gregorio and San Paolo, and saw the ruins, which must have belonged to the Coliseum, for the architecture is exactly similar, and they have every appearance of having been the Vivarium from their shape. To the Corsini Palace, containing one of the best collections of pictures, of which the finest are two portraits of cardinals by Raphael and Domenichino. The palace is very fine, and the villa joins it on the opposite hill of the Janiculum, but both are affected by the malaria. Then to the Vatican and saw all the frescoes and pictures; the collection of pictures is very small, but they are all masterpieces. To the gallery below to see the mosaics and the process of copying the great pictures. The coloured bits are numbered, and though there are not above six or seven colours, the sub-divisions of various shades amount to 18,000. This art is in a great degree mechanical, but requires ingenuity, attention, and some knowledge of painting.
