That the outlaw and he who has dropped out of the ranks of ordered social life, and he who seeks to prey on civilised society should naturally, instinctively, make the cave his home, is what we might expect. He is reverting to the habits of early man whose hand was against every man. In the "Two Gentlemen of Verona," the outlaws are presented as living in a cave. The robbers in "Gil Blas" had their lair also in one. One of the finest and most pathetic of Icelandic Sagas is the history of Grettir the Outlaw, who was born in 997, and killed by his enemies in 1031. He spent nineteen years in outlawry in Iceland, and outlawry there in that terrible climate, with no house to cover his head, would seem an ordeal impossible for human endurance. Between the autumn of 1022 and the spring of 1024, that is to say during two winters, he lived in a cave in the west of the island. A steep shale slide was below a cliff, and above this a hollow in the rock. He built up the mouth of the cave, and hung grey wadmal before the entrance, so that none below could notice anything peculiar, or any one living there. Whatever fuel he wanted, all he had to eat, everything he needed, had to be carried up this slippery ascent by him. Down the shale slide he went when short of provisions, and over the marshes to this or that farm and demanded or carried off, sometimes a sheep, sometimes curds, dried fish--in a word what he required. In the summer of 1862 a very similar lair which Grettir inhabited a little later in the east of Iceland was explored by a farmer living near. This is his description of it: "The lair stands in the upper part of a slip of stones beneath some sheer rocks. It is built up of stones, straight as a line, four and three-quarter ells long and ten inches wide, and is within the walls seven-eighths of an ell deep. Half of it is roofed over with flat stones; small splinters of stone are wedged in between these to fill up the joints, and these are so firmly fixed that they could not be removed without tools. One stone in the south wall is so large that it would require six men to move it. The north wall is beginning to give way. On the outside the walls are overgrown with black lichen and grey moss." A chapman spending the winter in a farm hard by, named Gisli the Dandy, heard that a price of nine marks of silver was placed on the head of Grettir. "Let me but catch him," said he, "and I will dress his skin for him."
