"In the fifth century, just as now, the sun rose every morning and every evening retired to rest. In the morning, when the first rays kissed the dew, the earth revived, the air was filled with the sounds of rapture and hope; while in the evening the same earth subsided into silence and plunged into gloomy darkness. One day was like another, one night like another. From time to time a storm-cloud raced up and there was the angry rumble of thunder, or a negligent star fell out of the sky, or a pale monk ran to tell the brotherhood that not far from the monastery he had seen a tiger -- and that was all, and then each day was like the next."
