The hetaerae of the various schools surpassed the men in their imitation of the jargon and the manners of the leading lights of their systems. Many of the philosophers yielded themselves readily to the seductions of their beautiful and clever adherents; yet there were some choice spirits who deplored the demoralizing tendencies which hetairism brought into serious pursuits, and protested in no uncertain language. These philosopher-hetaerae were indisputably the most interesting phenomenon in the social life of ancient times, to which the later Greek world and modern times afford no adequate parallel. They were present always at theatrical exhibitions and on all public occasions when respectable women remained at home. They took an absorbing interest in politics and in all public affairs; they discussed with the citizens the burning questions of the day; they criticised the acts of statesmen, the speeches of orators, the dramas of the poets, the productions of painters and sculptors. They exerted, in a word, an enormous influence for good or ill on the social and political life of the day; while they themselves had the consciousness of a mission to perform in having in their hands the real power of their sex. Almost every great man in Athens had his "companion," usually in addition to a lawful wife. Plato had Archeanassa, to whom he wrote sonnets; but we know not what were her attractions. "For dear to me Theoris is," sings Sophocles; and we should like to know more of Archippa, to whom he left his fortune. Aristotle had his Herpyllis, and the eloquent Isocrates his Metaneira. Speusippus, Plato's successor, found a "companion" in Lasthenia, and Epicurus in Leontium. It is difficult to believe that all these for whom the learned men of the day showed such regard were vicious women; in fact, some of them are described as noble and high-minded. "She was a citizen, without a guardian Or any near relations, and her manner Pure, and on virtue's strictest model form'd, A genuine mistress [Greek: heraira]: for the rest of the crew Bring into disrepute, by their vile manner, A name which in itself has nothing wrong."
