We now find ourselves in the _Piazza del Campidoglio_, occupying the Intermontium, where Brutus harangued the people after the murder of Julius Cæsar. In the centre of the square is the famous _Statue of Marcus Aurelius_, the only perfect ancient equestrian statue in existence. It was originally gilt, as may still be seen from marks of gilding upon the figure, and stood in front of the arch of Septimius-Severus. Hence it was removed by Sergius III. to the front of the Lateran, where, not long after, it was put to a singular use by John XIII., who hung a refractory prefect of the city from it by his hair.[39] During the rejoicings consequent upon the elevation of Rienzi to the tribuneship in 1347, one of its nostrils was made to flow with water and the other with wine. From its vicinity to the Lateran, so intimately connected with the history of Constantine, it was supposed during the middle ages to represent that Christian emperor, and this fortunate error alone preserved it from the destruction which befell so many other ancient imperial statues. Michael Angelo, when he designed the buildings of the Capitoline Piazza, wished to remove the statue to its present site, but the canons of the Lateran were unwilling to part with their treasure, and only consented to its removal upon an annual acknowledgment of their proprietorship, for which a bunch of flowers is still presented once a year by the senators to the chapter of the Lateran. Michael Angelo, standing in fixed admiration before this statue, is said to have bidden the horse "Cammina." Even until late years an especial guardian has been appointed to take care of it, with an annual stipend of ten scudi a year, and the title of "Il custode del Cavallo." "They stood awhile to contemplate the bronze equestrian statue of Marcus Aurelius. The moonlight glistened upon traces of the gilding which had once covered both rider and steed; these were almost gone, but the aspect of dignity was still perfect, clothing the figure as it were with an imperial robe of light. It is the most majestic representation of the kingly character that ever the world has seen. A sight of the old heathen emperor is enough to create an evanescent sentiment of loyalty even in a democratic bosom, so august does he look, so fit to rule, so worthy of man's profoundest homage and obedience, so inevitably attractive of his love. He stretches forth his hand with an air of proud magnificence and unlimited authority, as if uttering a decree from which no appeal was permissible, but in which the obedient subject would find his highest interests consulted: a command that was in itself a benediction."--_Hawthorne._
