The vast buildings which covered the Imperial hill, though discoloured by the lapse of ages and hung with ivy, had suffered little diminution of their external majesty; time had made them venerable, but had not shattered their walls. For two centuries and a half, they had stood all but desolate, and within that time had thrice been sacked by barbarians, yet something of the riches and art which made their ancient glory was still discoverable in the countless halls and chambers; statues, busts, mural paintings, triumphs of mosaic, pictured hangings, had in many parts escaped the spoiler and survived ruin; whilst everywhere appeared the magnificence of rare stones, the splendours of royal architecture, the beauty of unsurpassed carving. Though owls nested where empresses were wont to sleep, and nettles pierced where the lord of the world feasted his courtiers, this was still the Palace of those who styled themselves Ever August; each echo seemed to repeat an immortal name, and in every gallery seemed to move the shadows of a majestic presence. Belisarius had not resided here, preferring for his abode the palace of the Pincian. His successor in the military government of Rome chose a habitation on the deserted hill, in that portion of its complex structures which had been raised by Vespasian and his sons. Thither the two visitors were now directing their steps. Having passed a gateway, where Marcian answered with a watchword the challenge of the guard, they ascended a broad flight of stairs, and stood before an entrance flanked with two great pillars of Numidian marble, toned by time to a hue of richest orange. Here stood soldiers, to whom again the password was given. Entering, they beheld a great hall, surrounded by a colonnade of the Corinthian order, whereon had been lavished exquisite carving; in niches behind the columns stood statues in basalt, thrice the size of life, representing Roman emperors, and at the far end was a tribune with a marble throne. This, once the hall of audience, at present served as a sort of antechamber; here and there loitered a little group of citizens, some of whom had been waiting since early morning for speech with the commander; in one corner, soldiers played at dice, in another a notary was writing at a table before which stood two ecclesiastics. Voices and footsteps made a faint, confused reverberation under the immense vault.
