At midnight The moon arose; and lo! the ethereal cliffs Of Caucasus, whose icy summits shone Among the stars like sunlight, and around Whose caverned base the whirlpools and the waves _355 Bursting and eddying irresistibly Rage and resound forever.--Who shall save?-- The boat fled on,--the boiling torrent drove,-- The crags closed round with black and jagged arms, The shattered mountain overhung the sea, _360 And faster still, beyond all human speed, Suspended on the sweep of the smooth wave, The little boat was driven. A cavern there Yawned, and amid its slant and winding depths Ingulfed the rushing sea. The boat fled on _365 With unrelaxing speed.--'Vision and Love!' The Poet cried aloud, 'I have beheld The path of thy departure. Sleep and death Shall not divide us long.' The boat pursued The windings of the cavern. Daylight shone _370 At length upon that gloomy river's flow; Now, where the fiercest war among the waves Is calm, on the unfathomable stream The boat moved slowly. Where the mountain, riven, Exposed those black depths to the azure sky, _375 Ere yet the flood's enormous volume fell Even to the base of Caucasus, with sound That shook the everlasting rocks, the mass Filled with one whirlpool all that ample chasm: Stair above stair the eddying waters rose, _380 Circling immeasurably fast, and laved With alternating dash the gnarled roots Of mighty trees, that stretched their giant arms In darkness over it. I' the midst was left, Reflecting, yet distorting every cloud, _385 A pool of treacherous and tremendous calm. Seized by the sway of the ascending stream, With dizzy swiftness, round, and round, and round, Ridge after ridge the straining boat arose, Till on the verge of the extremest curve, _390 Where, through an opening of the rocky bank, The waters overflow, and a smooth spot Of glassy quiet mid those battling tides Is left, the boat paused shuddering.--Shall it sink Down the abyss? Shall the reverting stress _395 Of that resistless gulf embosom it? Now shall it fall?--A wandering stream of wind, Breathed from the west, has caught the expanded sail, And, lo! with gentle motion, between banks Of mossy slope, and on a placid stream, _400 Beneath a woven grove it sails, and, hark! The ghastly torrent mingles its far roar, With the breeze murmuring in the musical woods. Where the embowering trees recede, and leave A little space of green expanse, the cove _405 Is closed by meeting banks, whose yellow flowers For ever gaze on their own drooping eyes, Reflected in the crystal calm. The wave Of the boat's motion marred their pensive task, Which naught but vagrant bird, or wanton wind, _410 Or falling spear-grass, or their own decay
