Aware that the city was architecturally unworthy of her position as capital of the Roman Empire, besides being vulnerable to fire and river floods, Augustus so improved her appearance that he could justifiably boast: "I found Rome built of bricks; I leave her clothed in marble."
Urbem neque pro maiestate imperii ornatam et inundationibus incendiisque obnoxiam excoluit adeo, ut iure sit gloriatus marmoream se relinquere, quam latericiam accepisset.
