That pass was well fitted to afford a scene for many of the dealings of those or these days. There the robber might lurk perfectly concealed in the dark nooks and crannies of the rocks, to spring forth upon the unwary traveller when least prepared--there a handful of men might defend the passage against an army--there, the gay, happy party might raise the wild echo of the mountains to their joyous songs--and there the artist might linger for long hours, studying the fantastic shapes into which the ground has been thrown, and filling up the shadowy recesses with forms such as Rosa loved to draw. For somewhat less than two miles, the road, which, even in those days, was a good and well-constructed highway, passed between two ranges of rocks. On one side--the left hand, going north--a stream ran by the side of the path, some twenty feet below its level; but the bank itself could be easily descended to the river, and the stream, though deep in some places, was easily to be crossed at others, where it spread out over fallen rocks and stones. But what was the use of crossing it? On the other side was no path, and nothing but tall, ragged cliffs, in some places upright and flat, as if they had been cut with a knife, in others assuming the most wild and fantastic forms. Here was a strange grinning face, of gigantic size, starting forth in stone from the surface of the cliff; there a whole statue standing out from the rocky mass, as if a sentinel guarding the pass; then would come a castle with towers and keep, ballium and barbican and all, and yet nought but mere rock, wrought by no hands but those of time, earthquake, and tempest. But every here and there, from pinnacle and point, or out of dell and cavern, would spring a dark pine or light green ash; and the sight of even vegetable life would harmonize the scene with human thoughts.
