The post which he held by this precarious tenure carried with it the title of king; but surely no crowned head ever lay uneasier, or was visited by more evil dreams, than his. For year in, year out, in summer and winter, in fair weather and in foul, he had to keep his lonely watch, and whenever he snatched a troubled slumber it was at the peril of his life. The least relaxation of his vigilance, the smallest abatement of his strength of limb or skill of fence, put him in jeopardy; grey hairs might seal his death-warrant. To gentle and pious pilgrims at the shrine the sight of him might well seem to darken the fair landscape, as when a cloud suddenly blots the sun on a bright day. The dreamy blue of Italian skies, the dappled shade of summer woods, and the sparkle of waves in the sun, can have accorded but ill with that stern and sinister figure. Rather we picture to ourselves the scene as it may have been witnessed by a belated wayfarer on one of those wild autumn nights when the dead leaves are falling thick, and the winds seem to sing the dirge of the dying year. It is a sombre picture, set to melancholy music--the background of forest showing black and jagged against a lowering and stormy sky, the sighing of the wind in the branches, the rustle of the withered leaves under foot, the lapping of the cold water on the shore, and in the foreground, pacing to and fro, now in twilight and now in gloom, a dark figure with a glitter of steel at the shoulder whenever the pale moon, riding clear of the cloud-rack, peers down at him through the matted boughs.
