kraken

kraken, legendary sea monster of Scandinavian and Norwegian lore, perhaps imagined from sightings ofgiant squids and octopi. Sailors have discussed giant sea monsters for thousands of years, and Danish historian Erik Pontoppidan described the kraken (as well as sea serpents and mermaids) in detail in his Natural History of Norway (first published in Danish in 1752), claiming the beast was "round, flat, and full of arms" and "the largest and most surprising of all the animal creation." The sea monster is also the subject of Alfred, Lord Tennyson’s poem “The Kraken” (1871):

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 sea-worms in his sleep,
Until the latter fire shall heat the deep;
Then once by man and angels to be seen,
In roaring he shall rise and on the surface die.
