Local tradition says that Count Henry II. and his wife Adelaide, walking here by night, saw the whole lake lighted up from within in uncanny fashion, and founded a monastery in order to counteract the spell. This deserted but scarcely ruined building still exists, and contains the grave of the founder; the twelfth-century decoration, rich and detailed, is almost whole in the oldest part of the monastery. The far-famed German tale of Genovefa of Brabant is here localized, and Henry's son Siegfried assigned to the princess as a husband, while the neighboring grotto of Hochstein is shown as her place of refuge. On our way back to the Rocky Gate we pass through the singular little town of Niedermendig, an hour's distance from the lake--a place built wholly of dark gray lava, standing in a region where lava-ridges seam the earth like the bones of antediluvian monsters, but are made more profitable by being quarried into millstones. There is something here that brings part of Wales to the remembrance of the few who have seen those dreary slate-villages--dark, damp, but naked, for moss and weeds do not thrive on this dampness as they do on the decay of other stones--which dot the moorland of Wales. The fences are slate; the gateposts are slate; the stiles are of slate; the very "sticks" up which the climbing roses are trained are of slate; churches, schools, houses, stables are all of one dark iron-blue shade; floors and roofs are alike; hearth-stones and threshold-stones, and grave-stones all of the same material. It is curious and depressing. This volcanic region of the Rhine, however, has so many unexpected beauties strewn pell-mell in the midst of stony barrenness that it also bears some likeness to Naples and Ischia, where beauty of color, and even of vegetation, alternate surprisingly with tracts of parched and rocky wilderness pierced with holes whence gas and steam are always rising.
