krake

— But the most horrible and hideous monster, that the fables of the Norway fishers have invented, is the krake, sea-horse, or hafgufu, which nobody ever pretends to have seen entire; yet the fishers give out, that when they find a place which is usually 80 or 100 fathoms deep, to be at certain times only 20 or 30, and see also a multitude of fishes allured to the spot, by a delicious exhalation which this creature emits, they conclude that they are over a krake; then they make haste to secure a good draught of fishes, but take care to observe when the soundings grow shallower, for then the monster is rising.
