In 590 there was a great plague in Rome. Pope Gregory the Great was leading a procession to Saint Peter’s Cathedral to pray for deliverance from the pestilence, when it is said the Destroying Angel appeared on the summit of the Tomb of Hadrian. The angel was sheathing his sword to signify that the plague was stopped. Since that time the building has been known as the Castle Sant' Angelo. In 610 Pope Boniface IV erected on the summit of the tomb the Chapel of St. Angelo inter Nubes in commemoration of this event. Several statues of the Archangel succeeded this. The present one was put there in 1743. Marozia, daughter of Theodora, held the tomb as a fort in the tenth century, and had Pope John X suffocated in a dungeon. A few years later Pope Benedict VI met a similar fate at the hands of Crescenzio, son of Theodora. In the latter part of the tenth century Crescentius, the consul, had a quarrel with the Pope and seized the fort. He held it bravely against Emperor Otto III who had marched into Rome in defense of the pope. Emperor Hadrian was an able military leader, and a just and wise civil ruler. His full name was Publius Ælius Hadrianus, and he was born at Rome on January 24, 76 A. D. He was such an ardent student of Greek that he was nicknamed Græculus, the “Greek.” He served in the campaign against the Dacians under his uncle, Emperor Trajan. At the latter’s death he became emperor. Hadrian died at Baiæ on July 10, 138. His remains were carried to Puteoli, from which place they were afterward taken to Rome.
