" In fact, the age of the Tyrants is the scene of a religious renaissance which on all sides throws up new ecstatic confessions of faith, new secret cults and new sects; but at first these develop underground and do not as yet reach the light of art. Thus we no longer find art being commissioned and stimulated by religion, but, on the contrary, we find in this period religious zeal being inspired by the increased skill of the artist. "
