Certain smaller provinces might be administered by men of another order, who were neither filled with the senatorial traditions nor had passed through the senatorial career. These were but "factors" or "agents" of Caesar, and among them were the Pontius Pilate, Felix, and Festus, who were administrators of Judaea in New Testament times.
Next in rank to the senatorial order stood that of the "Knights." If the senators represent, in a certain sense, the peerage and baronetage, the next order represents—also in a certain sense.—the knightage. Generally speaking, it comprehended what we should call the upper middle classes, and particularly those concerned in the higher walks of finance; such persons as, with us, would be the directors or managers of great companies and banks. It also included persons whom the head of the state chose to honour with something less than senatorial standing. Many of these men were extremely wealthy, but the minimum property qualification stood at only £3200, and Roman citizens who possessed that amount were rather apt to pose as knights, and to be commonly spoken of as such by a kind of courtesy title, although their names could not be found upon the authorised rolls. Though several emperors did their best to stop this practice, the endeavour was for the most part fruitless. Once in England the "esquires" were a class with certain recognised claims, but nothing could stop the polite tendency to add "Esq." to the name of a person on a private letter. The case was somewhat similar at Rome, although the practice did not proceed quite so far.
Nevertheless there was a distinct and official roll of "Roman knights," whom the head of the state had honoured with a public present of "the gold ring," a ceremony corresponding to the royal sword-stroke of modern times. This body, mounted on horses nominally presented by the public, and riding in procession through the streets, was reviewed and revised every year. Their roll was called, and if a name was omitted from its proper place, it meant—without explanation necessary—that by the pleasure of the emperor the person in question had ceased to be a knight. Every member of the already-mentioned higher or senatorial order was by right a knight until he actually became a senator, from which time he ceased to enjoy the privileges of a knight because he was enjoying those of the higher order rank. For there were privileges as well as disabilities in each case. As a senator could govern large provinces and command armies, but could not engage in purely financial business; so the knight could—and almost alone did—conduct the large financial enterprises of the Roman world, but could not command armies nor hold any of the great public offices or higher provincial appointments, except the governorship of Egypt. Relatively to the senators the emperor was technically only "first among equals"; he was the first senator, as well as the first man of the state. At this date a senator would hold a truly public office, civil or military, with or under this "superior equal," but he would not act as his personal agent or assistant. The Roman aristocrat had not yet learned to serve in that capacity, still less on the "household" staff of the autocrat. There were as yet no highly placed Romans serving as Lord High Chamberlain, much less as Private Secretary. The "knights" stood in a different position. They were prepared to be the emperor's personal agents, just as they were prepared to be the agents of any one else, if sufficiently remunerated. They would take his personal orders, whether in managing his estates, collecting his provincial revenues, or relieving him of some routine portion of his own official labour.
It follows that it was often more lucrative to be a knight than a senator, and a number of senators were not unwilling to give up their rank, for the same reasons which induce a modern peer to serve on companies or a peeress to open a shop. On the other hand many a knight would have declined to become a senator, at least until he had sufficiently feathered his nest. The inducement to become or remain a senator was the social rank, the honour and dignity, with their outward insignia and the deference paid to them, the front seat, and the reception at court. In these the wives also shared, and at Rome the influence of the wife could not be disregarded.
If you met a senator, or a person of senatorial rank, in the street, you would know him for such by the broad band of purple which ran down the front, and probably also down the back, of his tunic, and by the silver or ivory crescent which he wore upon his black shoes. His wife, it is perhaps needless to say made even more show of what is called the "broad stripe." If you met a knight, you would perceive his standing by his two narrow stripes of purple appearing upon the same part of his dress. Each would wear a gold ring; but that in itself would prove nothing, since, despite all attempts at prohibiting the custom, every Roman who could afford a gold ring permitted himself that luxury.
If you entered one of the large semicircular theatres, which are to be described in due course, you would find that the men wearing the broad stripe seated themselves in the chairs which stood upon the level in front of the stage, while those wearing the narrow stripes would occupy the first fourteen tiers of seats rising just behind them. No one else might, occupy those places. If some one who had been improperly posing as a knight, or who had been degraded from his rank because he had wasted his credit and his money and no longer possessed either £3200 or a reputation, ventured to seat himself in the fourteen rows in the hope of being unnoticed, he would be speedily called upon by the usher to withdraw. Snobs occasionally made the attempt, and, at a somewhat later date, we have an amusing epigram of Martial concerning one who repeatedly but unsuccessfully dodged the usher and who was at last compelled to kneel in the gangway opposite the end of the fourteenth row, where it might look to those behind as if he were sitting among the knights, while technically he could claim that he was not sitting at all.
Elsewhere also, as for instance at the chariot-races in the Circus, and at the gladiatorial shows in the amphitheatre, there were special places set apart for the two orders.
Below the senators and the knights came the "people,"—the "commons," or "third estate"—with all its usual grades and its usual variety of occupation or no occupation, of manners and character or absence of both. With the life of these, as with the life of a noble, we shall deal at the proper time.
So much for the Roman citizen proper. Other elements of the population were the foreigners. At Rome these were exceedingly numerous, and the city may in this respect be called—as indeed it was called—a microcosm, a small copy or epitome of the Roman world. Gauls, Africans, Greeks, Jews, Syrians, and Egyptians were perhaps the most commonly to be seen, but particularly prominent were the Greeks and the Jews. The Greeks were recognised above all as the clever men, the artists, the social entertainers, and the literary guides. The Jews, who formed a sort of colony in what is now known as Trastevere—the low-lying quarter across the Tiber—were not yet the princes of high finance. As yet they were chiefly the hucksters and petty traders, notorious for their strange habits and for the fanaticism of their religion, which nevertheless exercised a strange potency and made many proselytes even in high places, especially among the women. Poppaea, the wife of Nero himself, is commonly considered to have been such a proselyte, although the strange notion that she herself was a Jewess is without any sort of foundation. It is a common error to suppose that the Jews came to Rome only after the destruction of Jerusalem. The dispersion had occurred long before Rome had anything to do with Judaea, and naturally the enterprising Jew was to be found in all profitable places, whether in Alexandria, Antioch, Smyrna, Corinth, Rome, or farther afield.
In the political sense all these foreigners belonged to their own provinces and communities. They might be citizens there, but they were not citizens at Rome. At Rome they had no public claims and no official career, unless—as not seldom happened—they received, for some service or some distinction, the gift of the Roman citizenship. Sometimes the citizenship was given wholesale to a town, or even to a province. How the Hebrew father or grandfather of St. Paul became a Roman citizen, we do not know. Their own abilities or the emperor's favour might carry such citizens, or their children, up all the steps which were open to the ordinary Roman.
