It is clear, that notwithstanding their observance of prodigies and religious ceremonies, there prevailed a considerable spirit of free-thinking among the Romans in the age of Ennius. This is apparent, not merely from his translation of Euhemerus, and definition of the nature of Jupiter, in his _Epicharmus_, but from various passages in dramas adapted for public representation, which deride the superstitions of augurs and soothsayers, as well as the false ideas entertained of the worshipped divinities. Polybius, too, who flourished shortly after Ennius, speaks of the fear of the gods, and the inventions of augury, merely as an excellent political engine, at the same time that he reprehends the rashness and absurdity of those who were endeavouring to extirpate such useful opinions(223). The dramatic career which had been commenced by Livius Andronicus and Ennius, was most successfully prosecuted by PLAUTUS, who availed himself, still more even than his predecessors, of the works of the Greeks. The Old Greek comedy was excessively satirical, and sometimes obscene. Its subjects, as is well known, were not entirely fictitious, but in a great measure real; and neither the highest station, nor the brightest talents, were any security against the unrestrained invectives of the comic muse in her earliest sallies. Cratinus, Eupolis, and Aristophanes, were permitted to introduce on the stage the philosophers, generals, and magistrates of the state with their true countenances, and as it were in _propria persona_; a license which seems, in some measure, to have been regarded as the badge of popular freedom. It is only from the plays of Aristophanes that we can judge of the spirit of the ancient comedy. Its genius was so wild and strange, that it scarcely admits of definition: and can hardly be otherwise described, than as containing a great deal of allegorical satire on the political measures and manners of the Athenians, and parodies on their tragic poets.
