But there is one thing significant in the literary character of this period, otherwise so barren in works of taste and imagination. Those by whom the art of verse was practised are no longer 'Semi-Graeci' or humble provincials, but Romans of political or social distinction. The chief authors in the interval between the first and second era of Roman poetry are either members of the aristocracy or men of old family belonging to the equestrian order. And this connexion between literature and social rank continues till the close of the Republic. The poets of the Ciceronian age,--Hortensius, Memmius, Lucretius, Catullus, Calvus, Cinna, &c.--either themselves belonged to the governing class, or were men of leisure and independent means, living as equals with the members of that class. This circumstance explains much of the difference in tone between the literature of that age and both the earlier and later literature. The separation in taste and sympathy between the higher classes and the mass of the people which had begun in the days of Terence, grew wider and wider with the growth of culture and with the increasing bitterness of political dissensions. It was only among the rich and educated that poetry could now expect to find an audience; and the poetry written for them appealed, for the most part, to the convictions, tastes, pleasures, and animosities which they shared as members of a class, not, like the best Augustan poetry, to the higher sympathies which they might share as the depositaries of great national traditions. But if this poetry was too exclusively addressed to a class--a class too, though refined by culture, yet living for the most part the life of fashion and pleasure--it had the merit of being the sincere expression of men writing to please themselves and their equals. It was not called upon to make any sacrifice of individual conviction or public sentiment to satisfy popular taste or the requirements of an Imperial master.
