There was, however, another great Roman dignitary who held his office for life, which was one of transcendent importance. He was at the head of the college of priests, which had the superintendence of all matters of religion. The college of pontiffs, of which, under Julius Caesar, there were sixteen, were not priests, but stood above all priests, and regulated the worship of the gods, and punished offenses against religion. The chief pontiff lived in a public palace in the Via Sacra, and might also hold other offices. It is a great proof of the talents of Caesar and of the estimation in which he was held, that, at the age of thirty-seven, he was chosen to this high dignity, against the powerful opposition of Catulus, prince of the Senate, and when he had only reached the aedileship. [Sidenote: Assemblies of the people.] [Sidenote: The Comitia Cenuriata.] In regard to the assemblies of the people, where they voted for the great officers of state, it must be borne in mind that they were not made up of the rabble, but of the populus or the patricians till nearly the close of the republic. Each of the thirty curia had its building for the discussion of political and legal questions. They had also collectively an assembly, called _Comitia Curiata_, where the people voted on the measures proposed by the magistrates. The votes were given by the curiae, each curia having one collective vote. The assembly originated nothing, but decided upon the life of Roman citizens, upon peace and war, and the election of magistrates. This was the primitive form under the kings. But Servius Tullius instituted the _Comitia Centuriata_, and hence divided the populus into six property classes, and one hundred and ninety-three centuriae. The first class was composed of ninety-eight centuriae, with a property qualification of one hundred thousand asses; the second of twenty-two centuriae with seventy-five thousand asses; the third of twenty, with fifty thousand asses; the fourth of twenty-two, with twenty-five thousand asses; the fifth of thirty, with eleven thousand asses; and the sixth of any one of those below twelve and a half minae. Yet this class was the most numerous. The wealthier classes voted first, and when a majority of the centuries was obtained the voting stopped. Hence the power was virtually in the hands of the rich; for, united, they made a majority before the poorer classes were called upon to vote. The _Comitia Centuriata_ elected the magistrates and made laws, and formed the highest court of appeal, but all its decisions had to be sanctioned by the curiae, although in course of time the curia was a formality. The centuries met in the Campus Martius, and were presided over by the consuls, who read the names of the candidates. In the assemblies by centuries, the vote of the first class prevailed over all the others; in the _comitia_ by curiae the patricians were supreme.
