gradually disappeared under the empire; all provincial towns occupied the same relative position towards the capital, and approximated to each other by degrees in their individual organisation and administration. Everywhere we come upon a college of decuriones or civic magistrates,--composed of a greater or lesser number of members elected from among the wealthiest citizens or supplemented from the government departments of the city,--which gradually absorbed all authority and constituted the supreme governing body of the municipium, under the presidency of two or four chief magistrates (_duumviri_ or _quatuorviri_). In the prefecture cities the control of the administration and judicature was vested in a prefect annually appointed by Rome, under whom a number of elective municipal officers managed the current affairs of the city. The magistracies of all provincial towns were modelled, both as to titles and departments, upon those of the capital. The heads of the decuriones exercised jointly the functions of consuls and prætors, and were attended in public by lictors with fasces; the public revenue and expenditure was controlled by quæstors, ædiles superintended the markets and retail trades and were responsible for the town police; censors kept the lists of burgesses and the census records. In questions of criminal law, however, the decisive sentence was usually pronounced at Rome. The imperial court of appeal was the court of highest instance for the whole empire. In upper Italy, which Cæsar had been the first to transfer from the position of a province to that of an integral part of the Roman state and jurisdiction, the administration of justice in civil affairs--left in older municipalities to the municipal courts--was subject to considerable restriction. The rigid rule of the monarchy and the exact organisation and strict supervision of the municipal authorities obviated the danger of revolts and serious disturbances among the populace, and Italy (the capital and its vicinity only excepted) was clear of garrisons. The naval forces stationed at Ravenna and Misenum served to protect the coast and maritime towns, and in the hour of danger a sufficient army could always be summoned from Dalmatia and Pannonia. The imperial guard of prætorians (of which three cohorts consisting of one thousand men apiece were quartered in Rome, and the other six in the neighbouring towns) was mainly composed of Italians. It shared with a German and Batavian troop of horse the duty of guarding the palace and the sacred person of the monarch.
