"the snowy mountains, 'the palaces of nature,' were not changed"

   A description of the Alps from Canto III of George Byron's semi-autobiographical poem Childe Harold's Pilgrimage (LXII).  This is the first of several strange instances in Frankenstein of characters quoting from works which, while well known to Mary Shelley, had not yet been written at the time the story is set (See notes to page 75, page 104, and page 130)
