THE PALACE OF THE CÆSARS.

After the death of Alexander Severus, A.D. 235, we have little or no history of buildings upon the Palatine, and there are no remains the construction of which shows a later date. Indeed the emperors reigned but a short time down to Diocletian, except Gallienus, who, we know, had a palace and gardens on the Esquiline. Fifty years after Alexander Severus died a great blow was struck at the grandeur of Rome; for the colleagues in empire, Diocletian and Maximian, made new capitals at Milan and Nicomedia, and thus divided the seat of power and empire. In A.D. 302, eighteen years after his declaration, Diocletian came to Rome for the first time, to celebrate his triumph, making a short stay of two months. The year 312 witnessed a great change. On October 28 the great Constantine, the first Christian emperor, and a Briton, made his entry into the imperial city, which for years had ceased to give rulers to the empire, and was now to be the seat of government no longer. Constantine did not make a long stay in the city; and, after he had secured his power, removed in 330 the capital of the empire to Byzantium, which was named Constantinople, to decorate which Rome was stripped of statues, marbles, and works of art. In 356 Constantius visited Rome, which had been abandoned by her rulers and denied the splendours of the imperial court. "After his entry he retired into the imperial palace, where he enjoyed the luxury he had wished for." "He quitted Rome on the thirtieth day after his entry (29th May)" (Marcellinus). The same historian informs us that, "on the night of the 18th of March 362, the Temple of Apollo, on the Palatine, was burned down." Theodosius, in 394, entered Rome in triumph. Honorius, his son, in 403 celebrated the grandest triumph since that of Diocletian, one hundred years before. Indeed, during this long period but four emperors had paid flying visits only to their ancient capital, and the Palace of the Cæsars was falling into decay, as Claudian, the last of the Roman poets, sings. Honorius for a short time revived the glories and memories of the past; the curule chairs once more surrounded the rostra, and their emperor's voice was once more heard by the plebs, whilst they gazed with awe at the lictors with their gilt fasces. After Honorius's departure, Alaric, and the barbarians that were with him, in 410, "took Rome itself, which they pillaged, burning the greatest part of the magnificent structures and other admirable works of art it contained" (Socrates, "E. H." v. 10). In 417 Honorius again entered Rome in triumph, and endeavoured to restore the city, and invited fugitives from all parts to people it. This benefactor of the city was buried near the supposed remains of S. Peter in the Vatican basilica. In 425 Valentinian III., whilst still a boy, received the imperial purple in the ancient Palace of the Cæsars, at the hands of an ambassador of Theodosius; and, although Ravenna was the seat of his government, he frequently visited Rome and inhabited the imperial palace. During one of these visits, in 454, Aetius, the general, fell in the imperial palace, stabbed by the hand of the licentious emperor, who drew his sword for the first time to kill the general who had saved his empire. In the following year, March 27, he was himself assassinated in the Campus Martius during a review; and Petronius Maximus was declared emperor, but was in his turn soon after murdered. The third day thereafter, Genseric and his Vandals entered Rome, and plundered it of everything they could carry off, from the seven-branched candlestick to the common utensils of Cæsar's Palace, which they completely stripped. Avitus, a Gaul, the successor of Petronius, visited Rome for a short time, and was murdered on his return to Auvergne. After the throne had been vacant for ten months, Majorianus was made emperor by Ricimer, 457. He published an edict from Ravenna against destroying the ancient monuments of Rome and using the materials for building. Severus Libius was his successor, and he was poisoned within the walls of the Palatine, August 465. Anthemius entered Rome in a triumphal procession in April 467, and revived the Lupercalia games; he was put to death in the palace by Ricimer, who captured Rome, July 11, 472. From 472 to 476 there were four emperors, the last of whom, Romulus Augustus, abdicated in presence of the senate, who proclaimed the extinction of the Western Empire.

In A.D. 500 King Theodoric paid a visit of six months to Rome. After addressing the people from the Rostra ad Palmam, which stands at the head of the Forum, he took up his residence at the Palace of the Cæsars, and appointed officers to take care of the ancient monuments. After his death, Athalaric and his mother governed till the former's death in 534. Theodatus, his successor, was murdered on the Flaminian Way, as he was retreating before Belisarius, the general of the Eastern emperor Justinian, who fixed his quarters at the Pincian Palace. In 549 Totila captured the city, and resided in the Palace of the Cæsars, exhibiting games in the Circus Maximus for the last time. During the winter of 552–553 Narses, the Eastern general, took Rome, and resided there, Rome being again united to the Eastern Empire, governed by an exarch, who generally resided at Ravenna. The history of the Palatine is a blank till the time of Heraclius I. Though not present himself, a coronation ceremony was held with great pomp in the Palace of the Cæsars, 610. A great event for Rome took place in 663. Then, for the last time, she received within her walls her emperor, Constans II., who contemplated again making her the capital of the empire. He was received by Pope Vitalianus at the Porta Appia with a procession of priests with tapers, banners, and crosses,—a curious contrast with former usages. Constans was the last emperor who resided in the Palace of the Cæsars, which was even then in a dilapidated condition; and his time seems to have been occupied with church ceremonies. His visit lasted twelve days, when he carried off what plunder he could, besides the gilt bronze tiles of the roof of the Pantheon. A blank again occurs till Justinian II., in 709, created the first Duke of Rome, who was afterwards elected by Pope and people, and resided in the Palace of the Cæsars. For many years the power of the Church of Rome had been increasing, and in 772 Pope Adrian I. threw off the nominal sovereignty of the Eastern Empire, and, calling upon Charlemagne to free him from the Lombard kings, he entered Rome on Saturday, April 2, Easter eve. Charlemagne confirmed Pepin's gifts to the Holy See. He again visited it, and on Christmas day A.D. 800 Pope Leo III. crowned him emperor in S. Peter's, with the title of Emperor of the Romans. From thence commenced the Holy Roman Empire.
