That the system afforded an opportunity to wealthy Romans to obtain for their children some understanding and appreciation of the culture of the Greek world with which their Empire was now in contact, and answered fairly well the preparatory needs along political and governmental lines of those Romans who could afford to educate their boys for such careers, can hardly be doubted (R. 22). Roman writers on education, especially Cicero (R. 24) and Quintilian (R. 25), give us abundant testimony as to the value and usefulness of the system evolved in the training of orators and men for the public service. In the provinces, too, we know that the schools were very useful in inculcating Roman traditions and in helping the Romans to assimilate the sons of local princes and leaders. [28] During the days of the Republic the schools were naturally more useful than after the establishment of the Empire, and especially after the later Emperors had stamped out many of the political and civic liberties for the enjoyment of which the schools prepared. On the other hand, the schools reached but a small, selected class of youths, trained for only the political career, and cannot be considered as ever having been general or as having educated any more than a small percentage of the future citizens of the State. Many of the important lines of activity in which the Romans engaged, and which to-day are regarded as monuments to their constructive skill and practical genius, such as architectural achievements, the building of roads and aqueducts, the many skilled trades, and the large commercial undertakings, these schools did nothing to prepare youths for. The State, unlike Athens, never required education of any one, did not make what was offered a preparation for citizenship, and made no attempt to regulate either teachers or instruction until late in the history of the Empire. Education at Rome was from the first purely a private- adventure affair, most nearly analogous with us to instruction in music and dancing. Those who found the education offered of any value could take it and pay for it; those who did not could let it alone. A few did the former, the great mass of the Romans the latter. For the great slave class that developed at Rome there was, of course, no education at all.
