The evening of that day, however (my friend and I returned in time for a late dinner), I wandered among the Roman remains of the place by the light of a magnificent moon, and gathered an impression which has lost little of its silvery glow. The moon of the evening before had been aqueous and erratic; but if on the present occasion it was guilty of any irregularity, the worst it did was only to linger beyond its time in the heavens, in order to let us look at things comfortably. The effect was admirable; it brought back the impression of the way, in Rome itself, on evenings like that, the moonshine rests upon broken shafts and slabs of antique pavement. As we sat in the theater, looking at the two lone columns that survive--part of the decoration of the back of the stage--and at the fragments of ruin around them, we might have been in the Roman forum. The arena at Arles, with its great magnitude, is less complete than that at Nîmes; it has suffered even more the assaults of time and of the children of time, and it has been less repaired. The seats are almost wholly wanting; but the external walls, minus the topmost tier of arches, are massively, ruggedly complete; and the vaulted corridors seem as solid as the day they were built. The whole thing is superbly vast, and as monumental, for a place of light amusement--what is called in America a "variety-show"--as it entered only into the Roman mind to make such establishments. The podium is much higher than at Nîmes, and many of the great white slabs that faced it have been recovered and put into their places. The proconsular box has been more or less reconstructed, and the great converging passages of approach to it are still majestically distinct; so that, as I sat there in the moon-charm stillness, leaning my elbows on the battered parapet of the ring, it was not impossible to listen to the murmurs and shudders, the thick voice of the circus, that died away fifteen hundred years ago.
