This personal head possessed a variety of titles which marked the various aspects of his rule—titles which survived into the Republic, and, on the differentiation of the functions which he united, were applied to various magistrates. As supreme judge he was _judex_, as leader and commander in war _praetor_,[160] _dictator_, and _magister populi_.[161] The most general title which marked him out as universal head of the state, in religious as in civil matters, was that of _rex_, the “regulator” of all things human and divine—a title which survived in the _rex sacrorum_, the heir of the king in sacrifice and in ritual. The powers on which this position was based were summed up in the word _imperium_.[162] The severance of the king from the state, over which he ruled, was also expressed in certain outward signs (_insignia_), which distinguished him from the rest of the burgesses. He was preceded by twelve “summoners” (_lictores_),[163] each carrying a bundle of rods (_fasces_), and the axe-head gleamed from these bundles even within the walls, for the king’s military jurisdiction could be exercised within the city. His robe was of “purple,” or rather of scarlet—the colour in which most nations have seen an emblem of sovereignty—but his dress probably varied with the ritual which he was performing, and the three kinds of striped garment (_trabea_) which survived in the Republic—that of purple for the priestly office, of purple and saffron for augury, of purple striped with white for the _rex_[164]—were probably all vestments of the king. Tradition also assigns him the eagle-headed sceptre, the golden crown, the throne (_solium_),[165] and the chariot within the walls, from which the curule chair (_sella curulis_) was believed to be derived.[166] The statement that the triumphal _insignia_ of the Roman magistrate were but the revival of the ordinary adornments of the king[167] is extremely probable; for the crown, the _toga picta_ (a development of the purple robe),[168] and the chariot reappear in the Roman triumph.
