Supported by the army on one side, with his person secure, enjoying the right of initiative and the right of veto, this officer of the "commonwealth" became indeed the Colossus who bestrode the Roman world. He was invariably made also the Pontifex Maximus, or chief guardian of the religious interests of Rome. He might in addition receive other constitutional appointments--for example, that of supervisor or corrector of morals--whenever these might suit a special purpose. What more could a man desire, if he was satisfied to forego the name of autocrat so long as he possessed the substance? It was quite as much to the purpose to be called _Princeps_, or "head of the state," as to be called a king, like the Parthian or other Oriental monarchs. Among the Romans, therefore, "Princeps" was his regular title. The Graeco-Oriental half of the empire, which had long been accustomed to kings and to treating them almost as gods, frankly styled this head of the state "king" or "autocrat," but no true Roman would forget himself so far as to lapse into this vulgar truth. One other title, however, the Romans did attach to their "Princeps." Something was still wanting to bring home, to both the Roman and the provincial, the peculiarly exalted position of so great a man; something which should be a recognition of that majesty which made him almost divine, at least with the divinity that doth hedge a king. The title selected for this purpose was _Augustus_, a word for which there is no nearer English equivalent than "His Highness," or perhaps "His Majesty," if we imagine that term applied to one who, by a legal fiction, is not a king. The insane Caligula called himself, or let himself be called, "Lord and Master," and later Domitian temporarily added to this title "God," but even Nero claimed neither of these modest epithets. Here, then, is the position of Nero: Commander-in-chief of all the forces of Rome by land and sea, and master of its foreign policy; the titular protector of its commons and therefore inviolable of person and virtual controller of laws and resolutions; official head of the state religion; rejoicer in the style of "His Highness the Head of the State." To speak ill of him, or to do anything derogatory to his authority, was _lèse majesté_. [Illustration: FIG. 12.--COIN OF NERO. British Museum.] Reference has several times been made to the Senate. It is time now to speak briefly of that body. For the sake of clearness, however, we must include a survey of the recognised constituent elements or "orders" of Roman society.
