We have already mentioned that the outward state of the consul was far inferior to that of the regal office hedged round as it was with reverence and terror, that the regal name and the priestly consecration were withheld from him, and that the axe was taken away from his attendants. We have to add that, instead of the purple robe which the king had worn, the consul was distinguished from the ordinary burgess simply by the purple border of his toga, and that, while the king perhaps regularly appeared in public in his chariot, the consul was bound to accommodate himself to the general rule and like every other burgess to go within the city on foot. The Dictator These limitations, however, of the plenary power and of the insignia of the magistracy applied in the main only to the ordinary presidency of the community. In extraordinary cases, alongside of, and in a certain sense instead of, the two presidents chosen by the community there emerged a single one, the master of the army (-magister populi-) usually designated as the -dictator-. In the choice of dictator the community exercised no influence at all, but it proceeded solely from the free resolve of one of the consuls for the time being, whose action neither his colleague nor any other authority could hinder. There was no appeal from his sentence any more than from that of the king, unless he chose to allow it. As soon as he was nominated, all the other magistrates were by right subject to his authority. On the other hand the duration of the dictator's office was limited in two ways: first, as the official colleague of those consuls, one of whom had nominated him, he might not remain in office beyond their legal term; and secondly, a period of six months was fixed as the absolute maximum for the duration of his office. It was a further arrangement peculiar to the dictatorship, that the "master of the army" was bound to nominate for himself immediately a "master of horse" (-magister equitum-), who acted along with him as a dependent assistant somewhat as did the quaestor along with the consul, and with him retired from office--an arrangement undoubtedly connected with the fact that the dictator, presumably as being the leader of the infantry, was constitutionally prohibited from mounting on horseback. In the light of these regulations the dictatorship is doubtless to be conceived as an institution which arose at the same time with the consulship, and which was designed, especially in the event of war, to obviate for a time the disadvantages of divided power and to revive temporarily the regal authority; for in war more particularly the equality of rights in the consuls could not but appear fraught with danger; and not only positive testimonies, but above all the oldest names given to the magistrate himself and his assistant, as well as the limitation of the office to the duration of a summer campaign, and the exclusion of the
