Simon had been a soldier and a man of affairs before ever he forsook the world, and the meaning of all that he had seen was clear to him. History told him how the Roman world had ever been assailed by fresh swarms of Barbarians, coming from the outer darkness, and that the eastern Empire had already, in its fifty years of existence since Constantine had moved the capital of the world to the shores of the Bosphorus, been tormented in the same way. Gepidæ and Heruli, Ostrogoths and Sarmatians, he was familiar with them all. What the advanced sentinel of Europe had seen from this lonely outlying hill, was a fresh swarm breaking in upon the Empire, distinguished only from the others by its enormous, incredible size and by the strange aspect of the warriors who composed it. He alone of all civilised men knew of the approach of this dreadful shadow, sweeping like a heavy storm cloud from the unknown depths of the east. He thought of the little Roman posts along the Dniester, of the ruined Dacian wall of Trajan behind them, and then of the scattered, defenceless villages which lay with no thought of danger over all the open country which stretched down to the Danube. Could he but give them the alarm! Was it not, perhaps, for that very end that God had guided him to the wilderness? Then suddenly he remembered his Arian neighbour, who dwelt in the cave beneath him. Once or twice during the last year he had caught a glimpse of his tall, bent figure hobbling round to examine the traps which he laid for quails and partridges. On one occasion they had met at the brook; but the old theologian waved him away as if he were a leper. What did he think now of this strange happening? Surely their differences might be forgotten at such a moment. He stole down the side of the hill, and made his way to his fellow-hermit's cave. But there was a terrible silence as he approached it. His heart sank at that deadly stillness in the little valley. No glimmer of light came from the cleft in the rocks. He entered and called, but no answer came back. Then, with flint, steel, and the dry grass which he used for tinder, he struck a spark, and blew it into a blaze. The old hermit, his white hair dabbled with crimson, lay sprawling across the floor. The broken crucifix, with which his head had been beaten in, lay in splinters across him. Simon had dropped on his knees beside him, straightening his contorted limbs, and muttering the office for the dead, when the thud of a horse's hoofs was heard ascending the little valley which led to the hermit's cell. The dry grass had burned down, and Simon crouched trembling in the darkness, pattering prayers to the Virgin that his strength might be upheld.
