At Sparta, and in other states where oligarchical institutions prevailed, the citizens formed a sort of military class, strikingly similar to the military aristocracy of Feudal Europe. Their chief occupation was martial and gymnastic exercises and the administration of public affairs. The Spartans, it will be recalled, were forbidden by law to engage in trade. In other aristocratic states, as at Thebes, a man by engaging in trade disqualified himself for full citizenship. In the democratic states, however, speaking generally, labor and trade were regarded with less contempt. A considerable portion of the citizens were traders, artisans, and farmers. Life at Athens presented some peculiar features. All Attica being included in what we should term the corporate limits of the city, the roll of Athenian citizens included a large body of well-to-do farmers, whose residence was outside the city walls. The Attic plains, and the slopes of the half-encircling hills, were dotted with beautiful villas and inviting farmhouses. And then Athens being the head of a great empire of subject cities, a large number of Athenian citizens were necessarily employed as salaried officials in the minor positions of the public service, and thus politics became a profession. In any event, the meetings of the popular assembly and the discussion of matters of state engrossed more or less of the time and attention of every citizen. Again, the great Athenian jury-courts, which were busied with cases from all parts of the empire, gave constant employment to nearly one fourth of the citizens, the fee that the juryman received enabling him to live without other business. It is said that, in the early morning, when the jurymen were passing through the streets to the different courts, Athens appeared like a city wholly given up to the single business of law. Furthermore, the great public works, such as temples and commemorative monuments, which were in constant process of erection, afforded employment for a vast number of artists and skilled workmen of every class. In the Agora, again, at any time of the day, a numerous class might have been found whose sole occupation, as in the case of Socrates, was to talk. The writer of the "Acts of the Apostles" was so impressed with this feature of life at Athens that he summarized the habits of the people by saying, "All the Athenians, and strangers which were there, spent their time in nothing else, but either to tell or to hear some new thing." (Chap. xvii. 21.) SLAVERY.--There was a dark side to Greek life. Hellenic art, culture, refinement--"these good things were planted, like exquisite exotic flowers, upon the black, rank soil of slavery."
