The whole vast expanse was covered with horsemen, hundreds and thousands and tens of thousands, all riding slowly and in silence, out of the unknown east. It was the multitudinous beat of their horses' hoofs which caused that low throbbing in his ears. Some were so close to him as he looked down upon them that he could see clearly their thin, wiry horses, and the strange humped figures of their swarthy riders, sitting forward on the withers, shapeless bundles, their short legs hanging stirrupless, their bodies balanced as firmly as though they were part of the beast. In those nearest he could see the bow and the quiver, the long spear and the short sword, with the coiled lasso behind the rider, which told that this was no helpless horde of wanderers, but a formidable army upon the march. His eyes passed on from them and swept further and further, but still to the very horizon, which quivered with movement, there was no end to this monstrous cavalry. Already the vanguard was far past the island of rock upon which he dwelt, and he could now understand that in front of this vanguard were single scouts who guided the course of the army, and that it was one of these whom he had seen the evening before. All day, held spell-bound by this wonderful sight, the hermit crouched in the shadow of the rocks, and all day the sea of horsemen rolled onward over the plain beneath. Simon had seen the swarming quays of Alexandria, he had watched the mob which blocked the hippodrome of Constantinople, yet never had he imagined such a multitude as now defiled beneath his eyes, coming from that eastern skyline which had been the end of his world. Sometimes the dense streams of horsemen were broken by droves of brood-mares and foals, driven along by mounted guards; sometimes there were herds of cattle; sometimes there were lines of waggons with skin canopies above them; but then once more, after every break, came the horsemen, the horsemen, the hundreds and the thousands and the tens of thousands, slowly, ceaselessly, silently drifting from the east to the west. The long day passed, the light waned, and the shadows fell, but still the great broad stream was flowing by. But the night brought a new and even stranger sight. Simon had marked bundles of faggots upon the backs of many of the led horses, and now he saw their use. All over the great plain, red pin-points gleamed through the darkness, which grew and brightened into flickering columns of flame. So far as he could see both to east and west the fires extended, until they were but points of light in the furthest distance. White stars shone in the vast heavens above, red ones in the great plain below. And from every side rose the low, confused murmur of voices, with the lowing of oxen and the neighing of horses.
