[144] The remains of this rampart still exist. They are described in the _Mission Archéologique de Macédoine_, p. 103, carried out under the direction of M. Leon Heuzey, by order of Napoleon III., and published at Paris between 1864 and 1876. Augustus made Philippi into a colony, erecting a triumphal arch to celebrate his victory over Brutus, and placing there a large settlement of his veterans who secured for him this important outpost. The colonies which were thus dispersed along the military frontier, as we should put it in modern language, were specially privileged. All the settlers were Roman citizens, and the government of the colony was like that of the mother city itself, in the hands of two magistrates, called in Greek Strategoi, or in Latin Prætors,[145] who ruled according to the laws of the Twelve Tables and after Roman methods, though perhaps all the neighbouring cities were still using their ancient laws and customs handed down from times long prior to the Roman Conquest. The details given us by St. Luke are in the strictest accordance in all these respects with the facts which we know independently concerning the history and political status of Philippi. [145] The proper official title of the highest magistrates of a colony was Duumviri. The colonies where a Greek spirit prevailed did not like this title, and called themselves Prætors, or Στρατηγοί, as in the case of Philippi. In exact accordance with St. Luke's usage Cicero, a century earlier, tells us in one of his Epistles, speaking of the vanity of Capua, which was thoroughly Greek in spirit, and therefore very vain: "While in other colonies the magistrates are called Duumviri, these wish themselves to be styled Prætors," a weakness laughed at in Horace's _Satires_, lib. i., v. 34-6. Dion Chrysostom, a Greek rhetorician of St. Paul's day, mocks the Greeks for the same flashy spirit.
