DECLINE OF THE ROMAN EMPIRE 65 in this world, but how the human soul might return to God — a goal which the Neo-Platonists often sought to attain by asceticism or mortifying the flesh, by ceremonies of purifi- cation, and sometimes by magic and incantations. Their one supreme being, they believed, transcended all attempts at description and was outside and far above the world of nature, — a transcendent God.

Moreover, the efforts of men who were neither Greeks nor Latins by birth to write in those tongues resulted in a nat- ural falling-off in purity of style and diction, while they failed to introduce much new subject-matter. Public taste, too, had degenerated, and where Athens had supplied large audiences for the tragedies of ^Eschylus and Euripides, the people of the Roman Empire preferred pantomime, as the people of to-day prefer moving pictures.

Here we have a good illustration of how the decline of religion affected literature. Many had attended the performance of a drama by ^schy- lus, just as many listen to a sermon to-day, not because they especially enjoyed or even thoroughly comprehended it, but I
