REGION, in ancient Rome, was a part or division of the city. The regions were only four in number, till Augustus Cæsar's time, who divided the city into fourteen; over each of which he settled two surveyors, called curatores viarum, who were appointed annually, and took their divisions by lot. These fourteen regions contained four hundred and twenty-four streets, thirty-one of which were called greater or royal streets, which began at the gilt pillar that stood at the entry of the open place in the middle of the city. The extent of these divisions varied greatly, some being from 12,000 or 13,000 to 33,000 feet or upwards in circumference. Authors, however, are not agreed as to the exact limits of each. The curatores viarum wore the purple, had each two lictors in their proper divisions, had slaves under them to take care of fires that happened to break out. They had also two officers, called denunciatores, in each region, to give account of any disorders. Four vico-magistri also were appointed in each street, who took care of the streets allotted them, and carried the orders of the city to each citizen.
