From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
The influences which stimulated the growth of Roman literature were of a character altogether peculiar and hardly paralleled in any other nation. To estimate them correctly, it is necessary in the first place that we should glance at the instruction of the people and its recreations during this period.
Knowledge of Languages
Language lies at the root of all mental culture; and this was especially the case in Rome. In a community where so much importance was attached to speeches and documents, and where the burgess, at an age which is still according to modern ideas regarded as boyhood, was already entrusted with the uncontrolled management of his property and might perhaps find it necessary to make formal speeches to the assembled community, not only was great value set all along on the fluent and polished use of the mother-tongue, but efforts were early made to acquire a command of it in the years of boyhood.
