_Son._ Now since we have named most of the species of fish that roam about in the ocean, those that are worth mentioning or discussing, I should like to hear about those features of the land itself that are most worthy of mention. What do you think of the extraordinary fire which rages constantly in that country? Does it rise out of some natural peculiarity of the land, or can it be that it has its origin in the spirit world? And what do you think about those terrifying earthquakes that can occur there, or those marvelous lakes, or the ice which covers all the higher levels?
_Father._ As to the ice that is found in Iceland, I am inclined to believe that it is a penalty which the land suffers for lying so close to Greenland; for it is to be expected that severe cold would come thence, since Greenland is ice-clad beyond all other lands. Now since Iceland gets so much cold from that side and receives but little heat from the sun, it necessarily has an over-abundance of ice on the mountain ridges. But concerning the extraordinary fires which burn there, I scarcely know what to say, for they possess a strange nature. I have heard that in Sicily there is an immense fire of unusual power which consumes both earth and wood. I have also heard that Saint Gregory has stated in his _Dialogues_[212] that there are places of torment[213] in the fires of Sicily. But men are much more inclined to believe that there must be such places of torment in those fires in Iceland. For the fires in Sicily feed on living things, as they consume both earth and wood. Trees live; they grow and put forth green leaves; but they dry up and wither when they begin to die; therefore, since they die when they wither, they must be called living while they are green. The earth, too, must be called living, inasmuch as it sometimes yields much fruitage; and as soon as one crop is fallen into decay, it gives new growth. All living creatures, too, are formed of earth, and therefore it surely must be called living. Both these things, earth and wood, the fires of Sicily can burn and consume as nourishment. The fire of Iceland, however, will burn neither earth nor wood, though these be cast upon it; but it feeds upon stone and hard rock and draws vigor from these as other fires do from dry wood. And never is rock or stone so hard but that this fire will melt it like wax and then burn it like fat oil. But when a tree is cast upon the fire, it will not burn but be scorched only. Now since this fire feeds on dead things only and rejects everything that other fires devour, it must surely be said that it is a dead fire; and it seems most likely that it is the fire of hell, for in hell all things are dead.
