Thus the council limited the power of the assembly, the Areopagus supervised the council, while the courts of the people had the final decision in cases of appeal. As is well known, Solon could not carry out his own reforms, but was forced to leave the country. Had he been of a different nature and at once seized the government, or appealed to the people, as did his successor, Pisistratus, he might have made his measures of reform more effective. As it was, he was obliged to leave their execution to others. _Cleisthenes Continues the Reforms of Solon_.--Some years later (509 B.C.) Cleisthenes instituted other reforms, increasing the council to 500, the members of which might be drawn from the first three classes rather than the first, limiting the archonship to the first class, and breaking up the four ancient tribes formed from the nobility. He formed ten new tribes of religious and political unions, thus intending to break down the influence of the nobility. Although the popular assembly was composed of all citizens of the four classes, the functions of this body in the early period were very meagre. It gave them the privilege of voting on the principal affairs of the nation when the council desired them to assume the responsibility. The {238} time for holding it was in the beginning indefinite, it being only occasionally convened, but in later times there were ten[1] assemblies in each year, when business was regularly placed before it. Meetings were held in the market-place at first; later a special building was erected for this purpose. Sometimes, however, special assemblies were held elsewhere. The assembly was convoked by the prytanes, while the right of convoking extraordinary assemblies fell to the lot of the strategi. There were various means for the compulsion of the attendance of the crowd. There was a fine for non-attendance, and police kept out people who ought not to appear. Each assembly opened with religious service. Usually sucking pigs were sacrificed, which were carried around to purify the place, and their blood was sprinkled over the floor. This ceremony was followed by the offering of incense. This having been done, the president stated the question to be considered and summoned the people to vote.
