During our time together we did not have occasion to lead a very regular life: even at the abbey we remained up at night and collapsed wearily during the day, nor did we take part regularly in the holy offices. On our journey, however, he seldom stayed awake after compline, and his habits were frugal. Sometimes, also at the abbey, he would spend the whole day walking in the vegetable garden, examining the plants as if they were chrysoprases or emeralds; and I saw him roaming about the treasure crypt, looking at a coffer studded with emeralds and chrysoprases as if it were a clump of thorn apple. At other times he would pass an entire day in the great hall of the library, leafing through manuscripts as if seeking nothing but his own enjoyment (while, around us, the corpses of monks, horribly murdered, were multiplying). One day I found him strolling in the flower garden without any apparent aim, as if he did not have to account to God for his works. In my order they had taught me quite a different way of expending my time, and I said so to him. And he answered that the beauty of the cosmos derives not only from unity in variety, but also from variety in unity. This seemed to me an answer dictated by crude common sense, but I learned subsequently that the men of his land often define things in ways in which it seems that the enlightening power of reason has scant function.
During our period at the abbey his hands were always covered with the dust of books, the gold of still-fresh illumination, or with yellowish substances he touched in Severinus’s infirmary. He seemed unable to think save with his hands, an attribute I considered then worthier of a mechanic: but even when his hands touched the most fragile things, such as certain freshly illuminated codices, or pages worn by time and friable as unleavened bread, he possessed, it seemed to me, an extraordinarily delicate touch, the same that he used in handling his machines. I will tell, in fact, how this strange man carried with him, in his bag, instruments that I had never seen before then, which he called his wondrous machines. Machines, he said, are an effect of art, which is nature’s ape, and they reproduce not its forms but the operation itself. He explained to me thus the wonders of the clock, the astrolabe, and the magnet. But at the beginning I feared it was witchcraft, and I pretended to sleep on certain clear nights when he (with a strange triangle in his hand) stood watching the stars. The Franciscans I had known in Italy and in my own land were simple men, often illiterate, and I expressed to him my amazement at his learning. But he said to me, smiling, that the Franciscans of his island were cast in another mold: “Roger Bacon, whom I venerate as my master, teaches that the divine plan will one day encompass the science of machines, which is natural and healthy magic. And one day it will be possible, by exploiting the power of nature, to create instruments of navigation by which ships will proceed unico homine regente, and far more rapid than those propelled by sails or oars; and there will be self-propelled wagons ‘and flying apparatuses of such form that a man seated in them, by turning a device, can flap artificial wings, ad modum avis volantis. And tiny instruments will lift huge weights and vehicles will allow travel on the bottom of the sea.”
When I asked him where these machines were, he told me that they had already been made in ancient times, and some even in our own time: “Except the flying instrument, which I have never seen or known anyone who has seen,. but I know of a learned man who has conceived it. And bridges can be built across rivers without columns or other support, and other unheard-of machines are possible. But you must not worry if they do not yet exist, because that does not mean they will not exist later. And I say to you that God wishes them to be, and certainly they already are in His mind, even if my friend from Occam denies that ideas exist in such a way; and I do not say this because we can determine the divine nature but precisely because we cannot set any limit to it.” Nor was this the only contradictory proposition I heard him utter; but even now, when I am old and wiser than I was then, I have not completely understood how he could have such faith in his friend from Occam and at the same time swear by the words of Bacon, as he was accustomed to doing. It is also true that in those dark times a wise man had to believe things that were in contradiction among themselves.
There, of Brother William I have perhaps said things without sense, as if to collect from the very beginning the disjointed impressions of him that I had then. Who he was, and what he was doing, my good reader, you will perhaps deduce better from the actions he performed in the days we spent in the abbey. Nor do I promise you an accomplished design, but, rather, a tale of events (those, yes) wondrous and awful.
And so, after I had come to know my master day by day, and spent the many hours of our journey in long conversations which, when appropriate, I will relate little by little, we reached the foot of the hill on which the abbey stood. And it is time for my story to approach it, as we did then, and may my hand remain steady as I prepare to tell what happened.
FIRST DAY
PRIME
It was a beautiful morning at the end of November. During the night it had snowed, but only a little, and the earth was covered with a cool blanket no more than three fingers high. In the darkness, immediately after lauds, we heard Mass in a village in the valley. Then we set off toward the mountain, as the sun first appeared.
While we toiled up the steep path that wound around the mountain, I saw the abbey. I was amazed, not by the walls that girded it on every side, similar to others to be seen in all the Christian world, but by the bulk of what I later learned was the Aedificium. This was an octagonal construction that from a distance seemed a tetragon (a perfect form, which expresses the sturdiness and impregnability of the City of God), whose southern sides stood on the plateau of the abbey, while the northern ones seemed to grow from the steep side of the mountain, a sheer drop, to which they were bound. I might say that from below, at certain points, the cliff seemed to extend, reaching up toward the heavens, with the rock’s same colors and material, which at a certain point became keep and tower (work of giants who had great familiarity with earth and sky). Three rows of windows proclaimed the triune rhythm of its elevation, so that what was physically squared on the earth was spiritually triangular in the sky. As we came closer, we realized that the quadrangular form included, at each of its corners, a heptagonal tower, five sides of which were visible on the outside — four of the eight sides, then, of the greater octagon producing four minor heptagons, which from the outside appeared as pentagons. And thus anyone can see the admirable concord of so many holy numbers, each revealing a subtle spiritual significance. Eight, the number of perfection for every tetragon; four, the number of the Gospels; five, the number of the zones of the world; seven, the number of the gifts of the Holy Ghost. In its bulk and in its form, the Aedificium resembled Castel Ursino or Castel del Monte, which I was to see later in the south of the Italian peninsula, but its inaccessible position made it more awesome than those, and capable of inspiring fear in the traveler who approached it gradually. And it was fortunate that, since it was a very clear winter morning, I did not first see the building as it appears on stormy days.
