The ruin, always open, is deserted at this hour. The idea of entering it possessed me. The two stone giants, who guard the stone court, allowed me to pass. I crossed the dark porch, upon which the iron portcullis still hangs, and entered the court. The moon had almost disappeared beneath the clouds. There was only a pallid light in the sky.
Nothing is grander than that which has fallen. This ruin, illuminated in such a way, at such an hour, was indescribably sad, gentle, and majestic. I fancied that in the scarcely perceptible rustling of the trees and foliage there was something grave and respectful. I heard no footstep, no voice, no breath. In the court there was neither light, nor shadow; a sort of dreamful twilight outlined everything and veiled everything. The confused gaps and rifts allowed the feeble rays of moonlight to penetrate the most remote corners; and in the black depths of the inaccessible arches and corridors, I saw white figures, slowly gliding.
It was the hour when the façades of old abandoned buildings are no longer façades, but faces. I walked over the uneven pavement without daring to make any noise, and I experienced between the four walls of this enclosure that strange disquietude, that undefined sentiment which the ancients called “the horror of the sacred woods.” There is a kind of insurmountable terror in the sinister mingled with the superb.
However, I climbed up the green and damp steps of the old stairway without rails and entered the old roofless dwelling of Otho-Heinrich. Perhaps you will laugh; but I assure you that to walk at night through chambers which have been inhabited by people, whose doors are dismantled, whose apartments each have their peculiar signification, saying to yourself: “Here is the dining-room, here is the bedroom, here is the alcove, here is the mantel-piece,”—and to feel the grass under your feet and to see the sky above your head, is terrifying. A room which has still the form of a room and whose ceiling has been lifted off, as it were like the lid of a box, becomes a mournful and nameless thing. It is not a house, it is not a tomb. In a tomb you feel the soul of a man; in this place you feel his shadow.
As soon as I passed the Knights’ Hall I stopped. Here there was a singular noise, the more distinct because a sepulchral silence filled the rest of the ruin. It was a weak, prolonged, strident rattle, mingled at moments with a little, dry and rapid hammering, which at times seemed to come from the depths of the darkness, from a far-away copse, or the edifice itself; at times, from beneath my feet between the rifts in the pavement. Whence came this noise? Of what nocturnal creature was it the cry, or the knocking? I am not acquainted with it, but as I listen to it, I cannot help thinking of that hideous, legendary spinner who weaves rope for the gibbet.
However, nothing, nobody, not a living person is here. This hall, like the rest of the Palace, is deserted. I struck the pavement with my cane, the noise ceased, only to begin again a moment afterwards. I knocked again, it ceased, then it began again. Yet I saw nothing but a large frightened bat, which the blow of my cane on the stones had scared from one of the sculptured corbels of the wall, and which circled around my head in that funereal flight which seems to have been made for the interior of ruined towers....
At the moment I descended the flight of stairs the moon shone forth, large and brilliant, from a rift in the clouds; the Palace of Frederick IV., with its double pediment, suddenly appeared, magnificent and clear as daylight with its sixteen pale and formidable giants; while, at my right, Otho’s façade, a black silhouette against the luminous sky, allowed a few dazzling rays of moonlight to escape through its twenty-four windows.
I said clear as daylight—I am wrong. The moon upon ruins is more than a light,—it is a harmony. It hides no detail, it exaggerates no wounds, it throws a veil on broken objects and adds an indescribable, misty aureole of majesty to ancient buildings. It is better to see a palace, or an old cloister, at night than in the day. The hard brilliancy of the sunlight is severe upon the ruins and intensifies the sadness of the statues....
I went out of the Palace through the garden, and, descending, I stopped once more for a moment on one of the lower terraces. Behind me the ruin, hiding the moon, made, half down the slope, a large mass of shadow, where in all directions were thrown out long, dark lines, and long, luminous lines, which striped the vague and misty background of the landscape. Below me lay drowsy Heidelberg, stretched out at the bottom of the valley, the length of the mountain; all the lights were out; all the doors were shut; below Heidelberg I heard the murmur of the Neckar, which seemed to be whispering to the hill and valley; and the thoughts which filled me all the evening,—the nothingness of man in the Past, the infirmity of man in the Present, the grandeur of Nature, and the eternity of God,—came to me altogether, in a triple figure, whilst I descended with slow steps into the darkness between this river awake and living, this sleeping town, and this dead Palace.
