Erculio had slept on a pile of rags in a corner of the dungeon, leaving it to the guards to make sure that d'Ucello's order was carried out and Daoud remained awake. The guards were, as Erculio must have known they would be, halfhearted about carrying out their mandate. They poked and struck him with sticks at intervals, but they did not try to injure him. Daoud was even able to sleep for brief periods between their proddings. They let most of the candles in the dungeon go out, leaving the great stone chamber in semidarkness.
Erculio managed to talk to him when the two guards were dozing. He held up what looked like a large pearl.
"There is a swift-acting poison sealed inside this glass ball. When he comes to burn your prickle off, I will slip it into your mouth. When you feel the fire, break the ball with your teeth and swallow. It will look as though the pain killed you. If you can manage it, swallow the glass, too, so they do not find it in your mouth after you're dead."
So calm did Daoud's Sufi training keep him that he was able to wonder where Erculio had got such a thing, and how the poison was sealed inside the ball, and what kind of poison it was. He could even think calmly about what it would feel like when the poison was killing him.
Erculio was taking a huge chance, he realized. D'Ucello might well discover that poison had killed Daoud; the podesta was a very clever and knowledgeable man. And if he did discover the poison, he would, of course, reason that Erculio had done it. In the midst of his calm, Daoud felt admiration for the little bent man's courage.
Inevitably with the passing of so many hours, the pain of the cuts and bruises and burns he had already suffered, and the ache of lying in the same position with his limbs stretched beyond endurance, would at times break through the mental wall he had built up against it. Remembering the words of Sheikh Saadi—If pain comes despite your training, invite it into your soul's tent as you would a welcome guest—he allowed the pain to wash over him. And when the first acute shock of it had passed, he was able to restore the wall.
From time to time he would think of what was soon going to happen to him. And it would be like a spear of ice driven into his heart. Again, he let himself feel the terror, the anguish, the agonized wondering, When will he come? and then, when his mind was numbed by the horror of it, cast it out again.
If he had not had the training of those two great and very different masters, Sheikh Saadi and Fayum al-Burz, he would have been mad with terror by now. Each time the door to the dungeon opened, the spear of ice pierced him again. Would it be now that he would lose his manhood in pain beyond imagining, pain so great that he would gladly die at once?
When no one was nearby, Erculio came close, cursed at him loudly, punched him, and whispered, "He is gone much longer than he said he would be. It is late afternoon. I told you he does not want to do this."
But he will do it, Daoud thought.
