M. de la Ferronays, whose character is now so well known from the beautiful family memoirs of Mrs. Augustus Craven, is buried beneath the altar where this vision occurred. In the third chapel on the left is the tomb of Angelica Kauffmann; in the right aisle that of the Prussian artist, Schadow. The two angels in front of the choir are by _Bernini_, who intended them for the bridge of S. Angelo. Returning to the Corso, the Via S. Claudio (left) leads to the pretty little church of that name, adjoining the Palazzo Parisani. Behind, is the Church of Sta. Maria in Via. At the corner of the Piazza Colonna is the _Palazzo Chigi_, begun in 1526 by Giacomo della Porta, and finished by Carlo Maderno. It contains several good pictures and a fine library, but is seldom shown.[10] The most remarkable members of the great family of Chigi have been the famous banker Agostino Chigi, who lived so sumptuously at the Farnesina (see chap. 20), and Fabio Chigi, who mounted the papal throne as Alexander VII., and who long refused to have anything to do with the aggrandisement of his family, saying that the poor were the only relations he would acknowledge, and, like Christ, he did not wish for any nearer ones. To keep himself in mind of the shortness of earthly grandeur, this pope always kept a coffin in his room, and drank out of a cup shaped like a skull. The side of the _Piazza Colonna_, which faces the Corso, is occupied by the Post-Office. On its other sides are the Piombino and Ferrajuoli palaces, of no interest. In the centre is placed the fine _Column_, which was found on the Monte Citorio in 1709, having been originally erected by the senate and people A.D. 174, to the Emperor Marcus Aurelius Antoninus (adopted son of the Emperor Hadrian,--husband of his niece, Annia Faustina,--father of the Emperor Commodus). It is surrounded by bas-reliefs, representing the conquest of the Marcomanni. One of these has long been an especial object of interest, from being supposed to represent a divinity (Jupiter?) sending rain to the troops, in answer to the prayers of a Christian legion from Mitylene. Eusebius gives the story, stating that the piety of these Christians induced the emperor to ask their prayers in his necessity, and a letter in Justin Martyr (of which the authenticity is much doubted), in which Aurelius allows the fact, is produced in proof. The statue of St. Paul on the top of the column was erected by Sixtus V.; the pedestal also is modern.
