at the top, which seem so slight and airy in comparison with the severe solidity of the rest of the structure, and are but a poor substitute for the massive conical roof which originally covered the tomb. Nature has done her utmost for nigh two thousand years to bring back this monument to her own bosom, but she has been foiled in all her attempts,--the travertine blocks of its exterior, though fitted to each other without cement, being as smooth and even in their courses of masonry as when first constructed, and almost as free from weather-stains as if they had newly been taken from the quarry. Only on the broad summit, where medieval Vandals broke down the noble pile and desecrated it by their own inferior workmanship, has nature been able to effect a lodgment; and in the breaches of this fortress, which is but a thing of yesterday as compared with the monument, and yet is far more ruinous, she has planted bushes, trees, and thick festoons of ivy, as if laying her quiet finger upon the angry passions of man, and obliterating the memory of his evil deeds by her own fair and smiling growth. The sepulchral vault in the interior was not opened till the time of Paul III., about 1540, when a beautiful marble sarcophagus, adorned with bas-reliefs of the chase, was found in it, which is supposed to be that which stands at the present day in the court of the Palazzo Farnese. This is likely to be true, for it is well known that this Pope, who was a member of the Farnese family, unscrupulously despoiled ancient Rome of many of its finest works of art in order to build and adorn his new palace. A golden urn containing ashes is said to have been discovered at the same time; but if so, it has long since disappeared. On a marble panel below the frieze an inscription in bold letters informs us that this is the tomb of Caecilia Metella, daughter of Quintus Metellus,--who obtained the sobriquet of _Creticus_ for his conquest of Crete,--and wife of Crassus. She belonged to one of the most haughty aristocratic families of ancient Rome, whose members at successive intervals occupied the highest positions in the state, and several of whom were decreed triumphs by the senate on account of their success in war. Her husband was surnamed _Dives_ on account of his enormous wealth. He is said to have possessed a fortune equal to a million and a half pounds sterling; and to have given an entertainment to the whole Roman people in a time of scarcity, besides distributing to each family a quantity of corn sufficient to last three months. Along with Julius Caesar and Pompey, he formed the famous first Triumvirate. While the richest, he seems, notwithstanding the above-mentioned act of munificence, to have been one of the meanest of the Romans. He had no steady political principle; he was actuated by bitter jealousy towards his colleagues and rivals; and that unsuccessful expedition which he undertook against the Parthians, in
