I was too excited about our imminent venture to pay attention to the service, which ended almost without my noticing. The monks lowered their cowls over their faces and slowly filed out, to go to their cells. The church remained deserted, illuminated by the glow of the tripod.
“Now,” William said, “to work.”
We approached the third chapel. The base of the altar was really like an ossarium, a series of skulls with deep hollow eyesockets, which filled those who looked at them with terror, set on a pile of what, in the admirable relief, appeared to be tibias. William repeated in a low voice the words he had heard from Alinardo (fourth skull on the right, press the eyes). He stuck his fingers into the sockets of that fleshless face, and at once we heard a kind of hoarse creak. The altar moved, turning on a hidden pivot, allowing a glimpse of a dark aperture. As I shed light on it with my raised lamp, we made out some damp steps. We decided to go down them, after debating whether to close off the passage again behind us. Better not, William said; we did not know whether we would be able to reopen it afterward. And as for the risk of being discovered, if anyone came at that hour to operate the same mechanism, that meant he knew how to enter, and a closed passage would not deter him.
We descended perhaps a dozen steps and came into a corridor on whose sides there were some horizontal niches, such as I was later to see in many catacombs. But now I was entering an ossarium for the first time, and I was very much afraid. The monks’ bones had been collected there over the centuries, dug from the earth and piled in the niches with no attempt to recompose the forms of their bodies. Some niches had only tiny bones, others only skulls, neatly arranged in a kind of pyramid, so that one would not roll over another; and it was a truly terrifying sight, especially in the play of shadows the lamp created as we walked on. In one niche I saw only hands, many hands, now irrevocably interlaced in a tangle of dead fingers. I let out a cry in that place of the dead, for a moment sensing some presence above, a squeaking, a rapid movement in the dark.
“Mice,” William said, to reassure me.
“What are mice doing here?”
“Passing through, like us: because the ossarium leads to the Aedificium, and then to the kitchen. And to the tasty books of the library. And now you understand why Malachi’s face is so austere. His duties oblige him to come through here twice daily, morning and evening. Truly he has nothing to laugh about.”
“But why doesn’t the Gospel ever say that Christ laughed?” I asked, for no good reason. “Is Jorge right?”
“Legions of scholars have wondered whether Christ laughed. The question doesn’t interest me much. I believe he never laughed, because, omniscient as the son of God had to be, he knew how we Christians would behave. But here we are.”
And, in fact, the corridor was ending, thank God; new steps began. After climbing them, we would have only to push an ironclad wooden door and we would find ourselves behind the fireplace of the kitchen, just below the circular staircase leading to the scriptorium. As we went up, we thought we heard a noise above us.
We remained a moment in silence; then I said, “It’s impossible. No one came in before us. ...”
“Assuming this is the only way into the Aedificium. In centuries past this was a fortress, and it must have more secret entrances than we know of. We’ll go up slowly. But we have little choice. If we put out the light we can’t see where we are going; if we leave it burning we. give anyone upstairs the alarm. Our only hope is that if someone really is there, he will be afraid of us.”
We reached the scriptorium, emerging from the south tower. Venantius’s desk was directly opposite. The room was so vast that, as we moved, we illuminated only a few yards of wall at a time. We hoped no one was in the court, to see the light through the windows. The desk appeared to be in order, but William bent at once to examine the pages on the shelf below, and he cried out in dismay.
“Is something missing?” I asked.
“Today I saw two books here, one of them in Greek. And that’s the one missing. Somebody has taken it, and in great haste, because one page fell on the floor here.”
“But the desk was watched. …”
“Of course. Perhaps somebody grabbed it just a short while ago. Perhaps he’s still here.” He turned toward the shadows and his voice echoed among the columns. “If you are here, beware!” It seemed to me a good idea as William had said before, it is always better when the person who frightens us is also afraid of us.
William set down the page he had found under the desk and bent his face toward it. He asked me for more light. I held the lamp closer and saw a page, the first half of it blank, the second covered with tiny characters whose origin I recognized with some difficulty.
“Is it Greek?” I asked.
“Yes, but I don’t understand clearly.” He took his lenses from his habit and set them firmly astride his nose, then bent his head again.
“It’s Greek, written in a very fine hand, and yet in a disorderly way. Even with my lenses I have trouble reading it. I need still more light. Come closer. ...”
He had picked up the sheet of parchment, holding it to his face; and instead of stepping behind him and holding the lamp high over his head, I foolishly stood directly in front of him. He asked me to move aside, and as I did, I grazed the back of the page with the flame. William pushed me away, asking me whether I wanted to burn the manuscript for him. Then he cried out. I saw clearly that some vague signs, in a yellow-brown color, had appeared on the upper part of the page. William made me give him the lamp and moved it behind the page, holding the flame fairly close to the surface of the parchment, which he heated without setting it afire. Slowly, as if an invisible hand were writing “Mane, Tekel, Peres,” I saw some marks emerge one by one on the white side of the sheet as William moved the lamp, and as the smoke that rose from the top of the flame blackened the recto; the marks did not resemble those of any alphabet, except that of necromancers.
“Fantastic!” William said. “More and more interesting!” He looked around. “But it would be better not to expose this discovery to the tricks of our mysterious companion, if he is still here. ...” He took off his lenses, set them on the desk, then carefully rolled up the parchment and hid it inside his habit. Still amazed by this sequence of events, which were nothing if not miraculous, I was about to ask further explanations when all of a sudden a sharp sound distracted us. It came from the foot of the east stairway, leading to the library.
“Our man is there! After him!” William shouted, and we flung ourselves in that direction, he moving faster, I more slowly, for I was carrying the lamp. I heard the clatter of someone stumbling and falling. I ran, and found William at the foot of the steps, observing a heavy volume, its binding reinforced with metal studs. At that same moment we heard another noise, in the direction from which we had come. “Fool that I am!” William cried. “Hurry! To Venantius’s desk!”
I understood: somebody, from the shadows behind us, had thrown the volume to send us far away.
Once again William was faster than I and reached the desk first. Following him, I glimpsed among the columns a fleeing shadow, taking the stairway of the west tower.
Seized with warlike ardor, I thrust the lamp into William’s hand and dashed blindly off toward the stairs where the fugitive had descended. At that moment I felt like a soldier of Christ fighting all the legions of hell, and I burned with the desire to lay my hands on the stranger, to turn him over to my master. I tumbled down almost the whole stairway, tripping over the hem of my habit (that was the only moment of my life, I swear, when I regretted having entered a monastic order!); but at that same instant—and it was the thought of an instant—I consoled myself with the idea that my adversary was suffering the same impediment. And, further, if he had taken the book, he would have his hands full. From behind the bread oven I almost dived into the kitchen, and in the starry light that faintly illuminated the vast entrance, I saw the shadow I was pursuing as it slipped past the refectory door, then p
ulled this shut. I rushed toward the door, I labored a few seconds opening it, entered, looked around, and saw no one. The outside door was still barred. I turned. Shadows and silence. I noticed a glow advancing from the kitchen and I flattened myself against a wall. On the threshold of the passage between the two rooms a figure appeared, illuminated by a lamp. I cried out. It was William.
“Nobody around? I foresaw that. He didn’t go out through a door? He didn’t take the passage through the ossarium?”
“No, he went out through here, but I don’t know where!”
“I told you: there are other passages, and it’s useless for us to look for them. Perhaps our man is emerging at some distant spot. And with him my lenses.”
“Your lenses?”
“Yes. Our friend could not take the page away from me, but with great presence of mind, as he rushed past, he snatched my glasses from the desk.”
“Why?”
“Because he is no fool. He heard me speak of these notes, he realized they were important, he assumed that without my lenses I would be unable to decipher them, and he knows for sure that I would not entrust them to anyone else. In fact, now it’s as if I didn’t have them.”
“But how did he know about your lenses?”
“Come, come. Apart from the fact that we spoke about them yesterday with the master glazier, this morning in the scriptorium I put them on to search among Venantius’s papers. So there are many people who could know how valuable those objects are to me. Actually, I could read a normal manuscript, but not this one.” And he was again unrolling the mysterious parchment. “The part in Greek is written too fine and the upper part is too hazy. …”
He showed me the mysterious signs that had appeared as if by magic in the heat of the flame. “Venantius wanted to conceal an important secret, and he used one of those inks that leave no trace when written but reappear when warmed. Or else he used lemon juice. But since I don’t know what substance he used and the signs could disappear again: quickly, you who have good eyes, copy them at once as faithfully as you can, perhaps enlarging them a bit.” And so I did, without knowing what I was copying. It was a series of four or five lines, really necromantic, and I will reproduce only the very first signs, to give the reader an idea of the puzzle I had before my eyes:
When I had finished copying, William looked, unfortunately without lenses, holding my tablet at some distance from his nose. “It is unquestionably a secret alphabet that will have to be deciphered,” he said. “The signs are badly drawn, and perhaps you copied them worse, but it is certainly a zodiacal alphabet. You see? In the first line we have”—he held the page away from him again and narrowed his eyes with an effort of concentration—“Sagittarius, Sun, Mercury, Scorpio. …”
“And what do they mean?”
“If Venantius had been ingenuous he would have used the most common zodiacal alphabet: A equals Sun, B equals Jupiter. … The first line would then read ... Try transcribing this: RACQASVL. …” He broke off. “No, it means nothing, and Venantius was not ingenuous. He reformulated the alphabet according to another key. I shall have to discover it.”
“Is it possible?” I asked, awed.
“Yes, if you know a bit of the learning of the Arabs. The best treatises on cryptography are the work of infidel scholars, and at Oxford I was able to have some read to me. Bacon was right in saying that the conquest of learning is achieved through the knowledge of languages. Abu Bakr Ahmad ben Ali ben Washiyya an-Nabati wrote centuries ago a Book of the Frenzied Desire of the Devout to Learn the Riddles of Ancient Writings, and he expounded many rules for composing and deciphering mysterious alphabets, useful for magic practices but also for the correspondence between armies, or between a king and his envoys. I have seen other Arab books that list a series of quite ingenious devices. For example, you can substitute one letter for another, you can write a word backward, you can put the letters to reverse order, using only every other one; and then starting over again, you can, as in this case, replace letters with zodiacal signs, but attributing to the hidden letters their numerical value, and then, according to another alphabet, convert the numbers into other letters. …”
“And which of these systems can Venantius have used?”
“We would have to test them all, and others besides. But the first rule in deciphering a message is to guess what it means.”
“But then it’s unnecessary to decipher it!” I laughed.
“Not exactly. Some hypotheses can be formed on the possible first words of the message, and then you see whether the rule you infer from them can apply to the rest of the text. For example, here Venantius has certainly noted down the key for penetrating the finis Africae. If I try thinking that the message is about this, then I am suddenly enlightened by a rhythm. ... Try looking at the first three words, not considering the letters, but the number of the signs ... IIIIIIII IIIII IIIIIII. ... Now try dividing them into syllables of at least two signs each, and recite aloud: ta-ta-ta, ta-ta, ta-ta-ta. ... Doesn’t anything come to your mind?”
“No.”
“To mine, yes. ‘Secretum finis Africae’ … But if this were correct, then the last word should have the same first and sixth letter, and so it does, in fact: the symbol of the Earth is there twice. And the first letter of the first word, the S, should be the same as the last of the second: and, sure enough, the sign of the Virgin is repeated. Perhaps this is the right track. But it could also be just a series of coincidences. A rule of correspondence has to be found. ...”
“Found where?”
“In our heads. Invent it. And then see whether it is the right one. But with one test and another, the game could cost me a whole day. No more than that because—remember this—there is no secret writing that cannot be deciphered with a bit of patience. But now we risk losing time, and we want to visit the library. Especially since, without lenses, I will never be able to read the second part of the message, and you cannot help me because these signs, to your eyes ...”
“Graecum est, non legitur,” I finished his sentence, humiliated. “It is Greek to me.”
“Exactly; and you see that Bacon was right. Study! But we must not lose heart. We’ll put away the parchment and your notes, and we’ll go up to the library. Because tonight not even ten infernal legions will succeed in keeping us out.”
I blessed myself. “But who can he have been, the man who was here ahead of us? Benno?”
“Benno was burning with the desire to know what there was among Venantius’s papers, but I can’t see him as one with the courage to enter the Aedificium at night.”
“Berengar, then? Or Malachi?”
“Berengar seems to me to have the courage to do such things. And, after all, he shares responsibility for the library. He is consumed by remorse at having betrayed some secret of it; he thought Venantius had taken that book, and perhaps he wanted to return it to the place from which it comes. He wasn’t able to go upstairs, and now he is hiding the volume somewhere.”
“But it could also be Malachi, for the same motives.”
“I would say no. Malachi had all the time he wanted to search Venantius’s desk when he remained alone to shut up the Aedificium. I knew that very well, but there was no way to avoid it. Now we know he didn’t do it. And if you think carefully, we have no reason to think Malachi knows Venantius had entered the library and removed something. Berengar and Benno know this, and you and I know it. After Adelmo’s confession, Jorge may know it, but he was surely not the man who was rushing so furiously down the circular staircase. …”
“Then either Berengar or Benno ...”
“And why not Pacificus of Tivoli or another of the monks we saw here today? Or Nicholas the glazier, who knows about my glasses? Or that odd character Salvatore, who they have told us roams around at night on God knows what errands? We must take care not to restrict the field of suspects just because Benno’s revelations have oriented us in a single direction; perhaps Benno wanted to mislead us.”
“Bu
t he seemed sincere to you.”
“Certainly. But remember that the first duty of a good inquisitor is to suspect especially those who seem sincere to him.”
“A nasty job, being an inquisitor.”
“That’s why I gave it up. And as you say, I am forced to resume it. But come now: to the library.”
NIGHT
In which the labyrinth is finally broached, and the intruders have strange visions and, as happens in labyrinths, lose their way.
We climbed back up to the scriptorium, this time by the east staircase, which rose also to the forbidden floor. Holding the light high before us, I thought of Alinardo’s words about the labyrinth, and I expected frightful things.
I was surprised, as we emerged into the place we should not have entered, at finding myself in a not very large room with seven sides, windowless, where there reigned—as, for that matter, throughout the whole floor—a strong odor of stagnation or mold. Nothing terrifying.
The room, as I said, had seven walls, but only four of them had an opening, a passage flanked by two little columns set in the wall; the opening was fairly wide, surmounted by a round-headed arch. Against the blind walls stood huge cases, laden with books neatly arranged. Each case bore a scroll with a number, and so did each individual shelf; obviously the same numbers we had seen in the catalogue. In the midst of the room was a table, also covered with books. On all the volumes lay a fairly light coat of dust, sign that the books were cleaned with some frequency. Nor was there dirt of any kind on the floor. Above one of the archways, a big scroll, painted on the wall, bore the words “Apocalypsis Iesu Christi.” It did not seem faded, even though the lettering was ancient. We noticed afterward, also in the other rooms, that these scrolls were actually carved in the stone, cut fairly deeply, and the depressions had subsequently been filled with color, as painters do in frescoing churches.
