When Augustin landed at Ostia, he saw rise before him, closing the perspective of the _Via Appia_, the Septizonium of Septimus Severus--an imitation, doubtless, on a far larger scale, of the one at Carthage. This huge construction, water-works probably of enormous size, with its ordered columns placed line above line, was, so to speak, the portico whence opened the most wonderful and colossal architectural mass known to the ancient world. Modern Rome has nothing at all to shew which comes anywhere near it. Dominating the Roman Forum, and the Fora of various Emperors--labyrinths of temples, basilicas, porticoes, and libraries--the Capitol and the Palatine rose up like two stone mountains, fashioned and sculptured, under the heap of their palaces and sanctuaries. All these blocks rooted in the soil, suspended, and towering up from the flanks of the hills, these interminable regiments of columns and pilasters, this profusion of precious marbles, metals, mosaics, statues, obelisks--in all that there was something enormous, a lack of restraint which disturbed the taste and floored the imagination. But it was, above all, the excessive use of gold and gilding that astonished the visitor. Originally indigent, Rome became noted for its greed of gold. When the gold of conquered nations began to come into its hands, it spread it all over with the rather indiscreet display of the upstart. When Nero built the Golden House he realized its dream. The Capitol had golden doors. Statues, bronzes, the roofs of temples, were all gilded. All this gold, spread over the brilliant surfaces and angles of the architecture, dazzled and tired the eyes: _Acies stupet igne metalli_, said Claudian. For the poets who have celebrated it, Rome is the city of gold--_aurata Roma_. A Greek, such as Lucian, had perhaps a right to be shocked by this architectural debauch, this beauty too crushing and too rich. A Carthage rhetorician, like Augustin, could feel at the sight of it nothing but the same irritated admiration and secret jealousy as the Emperor Constans felt when he visited his capital for the first time.
