(103) The mountains tremble, and the earth, the vast Abyss of sea, and towering height of hills, When on them looks the Sovereign's awful eye:

(16) So in like manner the earth and stones have their descent; for when the Salitter kindled itself in nature, then all became very rugged, thick and dark, like a thick dark mist or cloud, which the astringent quality dried up hard with its coldness.

(6) Then was I still more fearful of the abyss; Because I fires beheld, and heard laments, Whereat I, trembling, all the closer cling. I saw then, for before I had not seen it, The turning and descending, by great horrors That were approaching upon divers sides. As falcon who has long been on the wing, Who, without seeing either lure or bird, Maketh the falconer say, "Ah me, thou stoopest," Descendeth weary, whence he started swiftly, Thorough a hundred circles, and alights Far from his master, sullen and disdainful; Even thus did Geryon place us on the bottom, Close to the bases of the rough-hewn rock, And being disencumbered of our persons, He sped away as arrow from the string.
