From moment to moment they increased with such fury one would have said the foundations of the world were about to collapse; yet, in spite of it all, the sky never appeared clearer. I was unable to find reasons for this and my desire of knowing the cause of so extraordinary an event urged me to walk towards the place whence the noise seemed to come.
I walked for about four hundred stadia, at the end of which I perceived in the middle of a very large field what looked like two balls which, after moving round each other for a very long time with a humming noise, came together and then recoiled; and I observed that the moment of the shock was that when these great noises were heard. Drawing nearer I perceived that what at a distance had seemed to me to be two balls were two animals; one of them, although round at the base, formed a triangle from the middle, and its very high head with red hair streaming upwards narrowed off in a pyramid shape, while its body was filled with holes like a sieve and one could see through these hollow places, which served it as pores, little flames issuing forth which seemed to cover it with fiery plumage.
Walking round I met a most venerable old man looking at this wonderful combat with as much curiosity as I. He signed to me to approach; I obeyed and we sat down beside each other.
I was about to ask him what motive had brought him into this country, but he closed my mouth with these words:
"Well, you shall know the motive which brought me into this country."
And immediately he related to me at length all the details of his journey. I leave you to imagine whether or no I was astounded. But my amazement was increased, for just as I was burning to ask him what demon revealed my thoughts to him, he exclaimed:
"No, no, 'twas not a demon revealed your thoughts to me."
This new trick of divination caused me to observe him with more attention than before and I noticed he was imitating my carriage, my gestures, my appearance, placed all his limbs and disposed all the features of his face on the pattern of mine; in short, my shadow in relief would not have represented me better.
"I see", he went on, "you are anxious to know why I imitate you, and I am glad to tell you. Know then that in order to understand what goes on inside you, I arrange all the parts of my body in an order similar to yours; for, by arranging all parts of me like you, I excite in myself by this disposal of my matter the same thought that is produced in you by this same disposal of your matter.
"You will conceive this effect to be possible if you have ever before observed that twins resembling each other have generally similar minds, passions and wills; to such an extent that two doubles were met with in Paris who had always undergone the same illnesses and the same health, had married without knowing the other's intention at the same hour of the same day, wrote each other letters, whose sense, wording and construction were the same and who composed the same sort of verses on the same subject, with the same conceits, the same turn and the same order. But you must see that if the composition of the organs of their bodies were similar in all circumstances they could only act in a similar manner, just as two equal instruments equally struck must give forth an equal harmony; and so when I model my body on yours and become, as it were, your twin, the same movement of matter must cause us both the same movement of the mind."
