At first, heard solemn o'er the verge of Heaven, The Tempest growls; but as it nearer comes, And rolls its awful burden on the wind, The Lightnings flash a larger curve, and more The Noise astounds; till overhead a sheet Of livid flame discloses wide, then shuts, And opens wider; shuts and opens still Expansive, wrapping ether in a blaze. Follows the loosen'd aggravated Roar, Enlarging, deepening, mingling, peal on peal, Crush'd, horrible, convulsing Heaven and Earth.
