Simon Melas stood long in bewilderment, wondering who this stranger could be. He had heard, as had every Christian, of those evil spirits which were wont to haunt the hermits in the Thebaid and on the skirts of the Ethiopian waste. The strange shape of this solitary creature, its dark outline and prowling, intent attitude, suggestive rather of a fierce, rapacious beast than of a man, all helped him to believe that he had at last encountered one of those wanderers from the pit, of whose existence, in those days of robust faith, he had no more doubt than of his own. Much of the night he spent in prayer, his eyes glancing continually at the low arch of his cell door, with its curtain of deep purple wrought with stars. At any instant some crouching monster, some horned abomination, might peer in upon him, and he clung with frenzied appeal to his crucifix, as his human weakness quailed at the thought. But at last his fatigue overcame his fears, and falling upon his couch of dried grass, he slept until the bright daylight brought him to his senses. It was later than was his wont, and the sun was far above the horizon. As he came forth from his cell, he looked across at the peak of rock, but it stood there bare and silent. Already it seemed to him that that strange dark figure which had startled him so was some dream, some vision of the twilight. His gourd lay where it had fallen, and he picked it up with the intention of going to the spring. But suddenly he was aware of something new. The whole air was throbbing with sound. From all sides it came, rumbling, indefinite, an inarticulate mutter, low, but thick and strong, rising, falling, reverberating among the rocks, dying away into vague whispers, but always there. He looked round at the blue, cloudless sky in bewilderment. Then he scrambled up the rocky pinnacle above him, and sheltering himself in its shadow, he stared out over the plain. In his wildest dream he had never imagined such a sight.
