ABSTRACT
WE have seen in the above chapter how there is such strength in ice that it can very easily support squadrons of warriors, both horse and foot. Now we must look at an underground cave near the coastal city called Viborg, very near those lands of the Muscovites.2 The secret property of this cavern is that, if an animal is cast into it alive, such a frightful noise is emitted from it that the exceptional volume deafens the ears of anyone nearby, and prevents their hearing, speaking, or even standing up.
