Then a miracle occurred. One of the last angels lingered, turned, and quietly approached me. I caught sight of his cavernous, staring, diamond eyes under the imposing arches of his brows. On the ribs of his outspread wings glistened what seemed like frost. The wings themselves were gray, an ineffable tint of gray, and each feather ended in a silvery sickle. His visage, the faintly smiling outline of his lips, and his straight clear forehead reminded me of features I had seen on earth. The curves, the gleaming, the charm of all the faces I had ever loved—the features of people who had long since departed from me—seemed to merge into one wondrous countenance. All the familiar sounds that came separately into contact with my hearing now seemed to blend into a single, perfect melody.
He came up to me. He smiled. I could not look at him. But, glancing at his legs, I noticed a network of azure veins on his feet and one pale birthmark. From these veins, from that little spot, I understood that he had not yet totally abandoned earth, that he might understand my prayer.
