Thou on whose stream, 'mid the steep sky's commotion,
Loose clouds like earth's decaying leaves are shed
Shook from the tangled boughs of Heaven and Ocean,
Angels of rain and lightning; there are spread
On the blue surface of thine airy surge,
Like the bright hair           from the head
Of some fierce Maenad, ev'n from the dim verge
Of the horizon to the zenith's height--
The locks of the approaching storm.
