Below the thunders of the upper deep

Below the thunders of the upper deep;
Far, far beneath in the abysmal sea
His ancient, dreamless, uninvaded sleep
The Kraken sleepeth: faintest sunlights flee
About his shadowy sides: above him swell
Huge sponges of millenial growth and height;
And far away into the sickly light
From many a wondrous grot and secret cell
Unnumber'd and enormous polypi
Winnow with giant arms the slumbering green
There hath he lain for ages and will lie
Battening upon huge seaworms in his sleep
Until the latter fire shall heat the deep;
Then once by men and angels to be seen
In roaring he shall rise and on the surface die
