• Speaking of the region to which Dante here alludes, Eustace, Classical Tour , I 71, says:⁠— “The descent becomes more rapid between Roveredo and Ala; the river, which glided gently through the valley of Trent, assumes the roughness of a torrent; the defiles become narrower; and the mountains break into rocks and precipices, which occasionally approach the road, sometimes rise perpendicular from it, and now and then hang over it in terrible majesty.” In a note he adds:⁠— “Amid these wilds the traveller cannot fail to notice a vast tract called the Slavini di Marco, covered with fragments of rock torn from the sides of the neighboring mountains by an earthquake, or perhaps by their own unsupported weight, and hurled down into the plains below. They spread over the whole valley, and in some places contract the road to a very narrow space. A few firs and cypresses scattered in the intervals, or sometimes rising out of the crevices of the rocks, cast a partial and melancholy shade amid the surrounding nakedness and desolation. This scene of ruin seems to have made a deep impression upon the wild imagination of Dante, as he has introduced it into the twelfth canto of the Inferno, in order to give the reader an adequate idea of one of his infernal ramparts.” ↩
