As a general rule, the heights in Rome were occupied by the better class of residents, and the hollows by the lower stratum of population. This was not indeed entirely so, for poor people no doubt lived on the Aventine, the Caelian, and parts of the Esquiline. But the Palatine was certainly an aristocratic quarter; the Carinae, the height looking down on the hollow where the Colosseum now stands, had many good houses, e.g. those of Pompeius and of Quintus Cicero, and we know of one man of great wealth, Atticus, who lived on the Quirinal.[37] It was in the narrow hollows leading down from these heights to the Forum, such as the Subura between Esquiline and Quirinal, and the Argiletum farther down near the Forum, that we meet in literature what we may call the working classes; the Argiletum, for example, was famous both for its booksellers and its shoemakers,[38] and the Subura is the typical street of tradesmen. And no doubt the big lodging-houses in which the lower classes dwelt were to be found in all parts of Rome, except the strictly aristocratic districts like the Palatine.
The whole free population may roughly be divided into three classes, of which the first two, constituting together the social aristocracy, were a mere handful in number compared with the third. At the top of the social order was the governing class, or _ordo senatorius_: then came the _ordo equester_, comprising all the men of business, bankers, money-lenders, and merchants (_negotiatores_) or contractors for the raising of taxes and many other purposes (_publicani_). Of these two upper classes and their social life we shall see something in later chapters; at present we are concerned with the "masses," at least 320,000 in number,[39] and the social problems which their existence presented, or ought to have presented, to an intelligent Roman statesman of Cicero's time.
Unfortunately, just as we know but little of the populous districts of Rome, so too we know little of its industrial population. The upper classes, including all writers of memoirs and history, were not interested in them. There was no philanthropist, no devoted inquirer like Mr. Charles Booth, to investigate their condition or try to ameliorate it. The statesman, if he troubled himself about them at all, looked on them as a dangerous element of society, only to be considered as human beings at election time; at all other times merely as animals that had to be fed, in order to keep them from becoming an active peril. The philosopher, even the Stoic, whose creed was by far the most ennobling in that age, seems to have left the dregs of the people quite out of account; though his philosophy nominally took the whole of mankind into its cognisance, it believed the masses to be degraded and vicious, and made no effort to redeem them.[40] The Stoic might profess the tenderest feeling towards all mankind, as Cicero did, when moved by some recent reading of Stoic doctrine; he might say that "men were born for the sake of men, that each should help the other," or that "Nature has inclined us to love men, for this is the foundation of all law";[41] but when in actual social or political contact with the same masses Cicero could only speak of them with contempt or disgust. It is a melancholy and significant fact that what little we do know from literature about this class is derived from the part they occasionally played in riots and revolutionary disorders. It is fortunately quite impossible that the historian of the future should take account of the life of the educated and wealthy only; but in the history of the past and especially of the last three centuries B.C., we have to contend with this difficulty, and can only now and then find side-lights thrown upon the great mass of mankind. The crime, the crowding, the occasional suffering from starvation and pestilence, in the unfashionable quarters of such a city as Rome, these things are hidden from us, and rarely even suggested by the histories we commonly read.
