The Senate of the Areopagus [It received its name from its place of meeting, which was a rocky eminence opposite the Acropolis, called the hill of Ares (Mars Hill)], is said by some writers to have been instituted by Solon; but it existed long before his time, and may be regarded as the representative of the Council of Chiefs in the Heroic age. Solon enlarged its powers, and intrusted it with the general supervision of the institutions and laws of the state, and imposed upon it the duty of inspecting the lives and occupations of the citizens. All archons became members of it at the expiration of their year of office. Solon laid only the foundation of the Athenian democracy by giving the poorer classes a vote in the popular assembly, and by enlarging the power of the latter; but he left the government exclusively in the hands of the wealthy. For many years after his time the government continued to be an oligarchy, but was exercised with more moderation and justice than formerly. Solon enacted numerous laws, containing regulations on almost all subjects connected with the public and private life of the citizens. He encouraged trade and manufactures, and invited foreigners to settle in Athens by the promise of protection and by valuable privileges. To discourage idleness a son was not obliged to support his father in old age, if the latter had neglected to teach him some trade or occupation. Solon punished theft by compelling the guilty party to restore double the value of the property stolen. He forbade speaking evil either of the dead or of the living.
