After all, his bones have been allowed to rest in peace, which is more than can be said of all that have been buried within the area of the church. Urban the Sixth had no such good fortune. He so much surprised the cardinals, as soon as they had elected him, by his vigorous moral reforms that they hastily retired to Anagni and elected an antipope of milder manners and less sensitive conscience. He lived to triumph over his enemies. In Piacenza he was besieged by King Charles of Naples. He excommunicated him, tortured seven cardinals whom he caught in the conspiracy and put five of them to death; overcame and slew Charles, refused him burial and had his body exposed to the derision of the crowd. The chronicler says that 'Italy, Germany, England, Hungary, Bohemia, Poland, Sicily and Portugal were obedient to the Lord Pope Urban the Sixth.' He died peacefully, and was buried in Saint Peter's in a marble sarcophagus.

But when Sixtus the Fifth, who also surprised the cardinals greatly, was in a fit of haste to finish the dome, the masons, wanting a receptacle for water, laid hands on Urban's stone coffin, pitched his bones into a corner, and used the sarcophagus as they pleased, leaving it to serve as a water-tank for many years afterwards.

In extending the foundations of the church, Paul the Third came upon the bodies of Maria and Hermania, the two wives of Honorius, the Emperor who 'disestablished' paganism in favour of Christianity. They were sisters, daughters of Stilicho, and had been buried in their imperial robes, with many rich objects and feminine trinkets; and they were found intact, as they had been buried, in the month of February, 1543. Forty pounds of fine gold were taken from their robes alone, says Baracconi, without counting all the jewels and trinkets, among which was a very beautiful lamp, besides a great number of precious stones. The Pope melted down the gold for the expenses of the building, and set the gems in a tiara, where, if they could be identified, they certainly exist today--the very stones worn by empresses of ancient Rome.

Then, as if in retribution, the Pope's own tomb was moved from its place. Despoiled of two of the four statues which adorned it, the monument is now in the tribune, and is still one of the best in the church. A strange and tragic tale is told of it. A Spanish student, it is said, fell madly in love with the splendid statue of Paul's sister-in-law, Julia Farnese. He succeeded in hiding himself in the basilica when it was closed at night, threw himself in a frenzy upon the marble and was found stone dead beside it in the morning. The ugly draperies of painted metal which now hide much of the statue owe their origin to this circumstance. Classical scholars will remember that a somewhat similar tale is told by Pliny of the Venus of Praxiteles in Cnidus.
