The heats of summer being over, autumn began to be temperate ... we (two friends, a heathen and a Christian) agreed to go to the delightful city of Ostia.... As, at break of day, we were proceeding along the banks of the Tiber towards the sea, that the soft breeze might invigorate our limbs, and that we might enjoy the pleasure of feeling the beach gently subside under our footsteps, Cæcilius observed an image of Serapis, and having raised his hands to his lips, after the wont of the superstitious vulgar, he kissed it.... Then Octavius said: 'It is not the part of a good man, brother Marcus, thus to leave an intimate companion and friend amidst blind popular ignorance, and to suffer him, in such open daylight, to stumble against stones,' etc.... Discoursing after this sort, we traversed the space between Ostia and the sea, and arrived at the open coast. There the gentle surges had smoothed the outermost sands like a pleasure walk, and as the sea, although the winds blow not, is ever unquiet, it came forward to the shore, not hoary and foaming, but with waves gently swelling and curled. On this occasion we were agreeably amused by the varieties of its appearance, for, as we stood on the margin and dipped the soles of our feet in the water, the wave alternately struck at us, and then receding, and sliding away, seemed to swallow up itself.

Observe the sea, it is bound by a law that the shore imposes; the variety of trees, how each of them is enlivened from the bowels of the earth! Behold the ocean, it ebbs and flows alternately. Look at the springs, they trickle with a perpetual flow; at rivers, they hold on their course in quick and continued motion. Why should I speak of the ridges of mountains, aptly disposed? of the gentle slope of hills, or of plains widely extended?... In this mansion of the world, when you fully consider the heaven and the earth, and that providence, order, and government visible in them, assure
