The school of writers which is interested in representing all forms of government, which have been successful as democratic, has done its best both in ancient and modern times to minimise the aristocratic character of the Roman Senate no less than its legislative supremacy; but the whole tone of Roman history is against them. A Roman Senator was distinctly a nobleman. Inside the Senate rank went by office; those Senators who had held the higher offices took precedence of others according to dignity of office; those families were most highly honoured who could show the greatest number of dignitaries among their ancestors, but the qualification of birth co-existed with rank, derived from office or a long ancestry of office holders. Long after the distinction between patrician and plebeian had ceased to have any meaning except in reference to certain priesthoods and religious ceremonies, the distinction between patrician and plebeian families was remembered, and occasionally reasserted itself practically; and it was some time before the official rank of Senator conferred by an Emperor was respected unless the recipient was entitled to Senatorial rank by descent. Among the few acts of the early Emperors which win the respect of contemporary historians, purgations of the Senate are included. Julius Cæsar tried to make the Senate a council of the Empire by enrolling in it non-Italians; but he was before his time, and his astute successor acted in a contrary spirit. During all the constitutional changes of the last centuries of the Republic, the position of the Roman Senate remained unchanged in two particulars: it was the fountain head of Roman religion and of Roman law, and though the former might be held to be of transitory importance, the latter was undeniably permanent in its effects.
