The national character of this poetry is attested also by the spirit and character which pervades it. Among all the authors who have been reviewed, Ennius alone possessed in a large measure that peculiar vein of imaginative feeling which is the most impressive element in the great poets of a later age. The susceptibility of his mind to the sentiment that moulded the institutions and inspired the policy of the Imperial Republic, entitles him to rank as the truest representative of the genius of his country, notwithstanding his apparent inferiority to Plautus in creative originality. The glow of moral passion, which is another great characteristic of Latin literature, as it was of the best types of the Latin race, reveals itself in the remains of all the serious writers of the age. The struggle between the old Roman self-respect and the new modes of temptation, is exemplified in the antagonistic influence exercised by the tragic, epic, and satiric poetry on the one hand, and the comedy of Plautus and Terence on the other. The more general popularity of comedy was a symptom of the facility with which the severer standard of life yielded to the new attractions. The graver writers, equally with the writers of comedy, shared in the sceptical spirit, or the religious indifference, which was one of the dissolving forces of social and political life during this age. The strong common sense which characterised all the writers of the time, could not fail to bring them into collision with the irrational formalism of the national religion; while the distaste for speculative philosophy which Ennius and Plautus equally express, and the strong hold which they all have on the immediate interests of life, explain the absence of any, except the most superficial, reflections on the more mysterious influences which in the belief of the great Greek poets moulded human destiny.
