We behold with admiration pyramids that were built by kings, when the very ground alone, that was purchased by the Dictator Cæsar, for the construction of his Forum, cost one hundred millions of sesterces! If, too, an enormous expenditure has its attractions for any one whose mind is influenced by monetary considerations, be it known to him that the house in which Clodius dwelt, who was slain by Milo, was purchased by him at the price of fourteen million eight hundred thousand sesterces! a thing that, for my part, I look upon as no less astounding than the monstrous follies that have been displayed by kings. And then, as to Milo himself, the sums in which he was indebted, amounted to no less than seventy millions of sesterces; a state of things, to be considered, in my opinion, as one of the most portentous phænomena in the history of the human mind. But it was in those days, too, that old men still spoke in admiration of the vast proportions of the Agger,[2627] and of the enormous foundations of the Capitol; of the public sewers, too, a work more stupendous than any; as mountains had to be pierced for their construction, and, like the hanging city[2628] which we recently mentioned, navigation had to be carried on beneath Rome; an event which happened in the ædileship[2629] of M. Agrippa, after he had filled the office of consul. For this purpose, there are seven rivers, made, by artificial channels, to flow beneath the city. Rushing onward, like so many impetuous torrents, they are compelled to carry off and sweep away all the sewerage; and swollen as they are by the vast accession of the pluvial waters, they reverberate against the sides and bottom of their channels. Occasionally, too, the Tiber, overflowing, is thrown backward in its course, and discharges itself by these outlets: obstinate is the contest that ensues within between the meeting tides, but so firm and solid is the masonry, that it is enabled to offer an effectual resistance. Enormous as are the accumulations that are carried along above, the work of the channels never gives way. Houses falling spontaneously to ruins, or levelled with the ground by conflagrations, are continually battering against them; the ground, too, is shaken by earthquakes every now and then; and yet, built as they were in the days of Tarquinius Priscus, seven hundred years ago, these constructions have survived, all but unharmed. We must not omit, too, to mention one remarkable circumstance, and all the more remarkable from the fact, that the most celebrated historians have omitted to mention it. Tarquinius Priscus having commenced the sewers, and set the lower classes to work upon them, the laboriousness and prolonged duration of the employment became equally an object of dread to them; and the consequence was, that suicide was a thing of common occurrence, the citizens adopting this method of escaping their troubles. For this evil, however, the king devised a singular remedy, and one that has
