The communities made their own by-laws, they collected the land-tax of their own district and handed it over to the financial representative of the Roman government. This was done by men of their own people, often of a low class, known in the Gospels as the "publicans," who were so commonly associated with sinners. St. Matthew had been one of the minor agents for such collection in Galilee. Other taxes--those which were indirect--might be collected by the great tax-farming companies of Roman "knights," who offered a lump sum for them to the government, and made what they could out of the bargain. One incidental consequence of this systematic division into communes was that there spread throughout the empire a strong municipal patriotism, especially in the Greek world. This was followed by liberal local expenditure on the part of rich provincials in beautifying their centres with public buildings and works of art, chiefly, no doubt, given for the sake of the local honours with which they were repaid, but given nevertheless. Most of the towns or communities throughout the empire were in the position described. Some communities, however, such as Thessalonica, though situated inside a province, were for some special service in the past exempted from the interference of the governor, and were allowed to exercise their own laws to the full, even upon Roman citizens who might happen to reside there. These were called "free" towns. In other cases the community, having come into voluntary alliance with Rome at an earl; date and before conquest, was still treated as an "allied" state, and was exempted from either interference or taxation, so long as it supplied its quota of soldiers when called upon. Such cities, however, were distinctly the exception, and most of them in the end preferred to come directly within the Roman sphere of administration. They often found their burdens smaller and less capricious than when they taxed themselves through their own authorities. * * * * * The function of the governor was to see that the various local bodies did their work, kept within their rights, and paid their taxes. He also, either in person or by his deputies, administered justice wherever the Roman laws were concerned. Where they were not concerned, he necessarily acted as Gallio did with the Jewish charges against Paul at Corinth; he dismissed the case as not demanding his jurisdiction. Said Gallio: "If it were a question of a misdemeanour or a crime, I should be called upon to bear with you; but if they are questions of (mere) words and names and of your (Jewish) law, you must see to it yourselves." When the Greeks who were standing by proceeded to beat the chief of Paul's Jewish accusers, the governor shut his eyes to the matter. This may have been a laxity, but it would almost appear as if Gallio liked their behaviour.
