After this he again settled himself to imitate me and went on thus: "You are now very anxious to know the origin of the battle of these two monsters, whereof I will inform you. Learn then that the trees of the forest behind us were not able to repulse the violent efforts of the Fire-Beast with their breath and therefore sought the aid of the Ice-Animal."

"I have only heard these animals spoken of", I said, "by an oak in this country, but this was in great haste, for it was only thinking of its safety; and so I beg you will inform me."

He spoke in this way: "In this globe where we are the woods would be very scattered, on account of the desolation caused them by the large number of Fire-Beasts, but for the Ice-Animals which every day at the request of their friends the forests come to heal these sick trees; I say heal, because as soon as their icy mouth breathes upon the coals of this plague they are extinguished.

"In the world of the Earth, whence you come and whence I come, the Fire-Beast is called a Salamander and the Ice-Animal is known by the name of Remora.[74] Well, you must know that the Remora dwells towards the extremity of the pole in the deepest part of the frozen sea, and it is the cold which evaporates from these fishes through their scales, which in those districts freezes the sea-water, although it is salt.

"The greater part of the pilots who have sailed to discover Greenland have noticed at one season of the year that the ice which stopped them at other seasons was no longer to be met with; but although this sea was free of ice at the time when winter is at its harshest they have not failed to attribute the cause to the melting of the ice by some secret warmth; but it is much more likely that the Remoræ, which feed on nothing but ice, had absorbed them at that time. You must know then that some months after they are filled this terrible digestion makes their bellies so cold that the mere breath they exhale freezes the whole Polar Sea again. When they come out on land (for they live in both elements) they feed on nothing but hemlock, aconite, opium, and mandragora.

"In our world people wonder whence come those chilly north winds, which always bring the frosts with them; but if our compatriots knew, as we do, that the Remoræ inhabit that climate, they would understand, as we do, that these winds come from the breath wherewith these fishes attempt to repulse the heat of the Sun as it approaches them.

"That Stygian water used to poison the great Alexander, whose cold petrified his entrails, was the piss of one of these animals. In short, the Remora contains so eminently all the principles of cold that when it passes under a ship, the ship is gripped by cold and remains so benumbed it cannot move from where it is. That is the reason why half of those who have sailed northward to discover the pole never returned, because it would be a miracle if the Remoræ, whose number is so great in that sea, did not stop their vessels. So much for the Ice-Animals.

"As to the Fire-Beasts, they dwell in the earth under mountains lighted by bitumen, such as Ætna, Vesuvius and the Red Cape. The pimples you see on this one's throat, which proceed from the inflammation of its liver, are...."[75]

After that we remained without speaking to watch this extraordinary duel.

The Salamander attacked with great ardour, but the Remora withstood him impenetrably. Each blow they exchanged caused a clap of thunder, as it happens in the worlds round about where the meeting of a warm with a cold cloud excites the same noise.
