To later Romans Ennius was the personification of the spirit of early Rome; by them he was called "The Father of Roman Poetry." We must remember how truly Greek he was in his point of view. He set the example for later Latin poetry by writing the first epic of Rome in Greek hexameter verses instead of in the old Saturnian verse. He made popular the doctrines of Euhemerus, and he was in general a champion of free thought and rationalism.
