"They would rather take what they want by looting or tribute or taxation. Eventually they think they will not have to trade. They believe the blue sky, which they worship, will permit them to conquer the whole world, and then all peoples will slave for them. Just as they use subject people, so, if you ally yourselves with them, they will use you. You will help them destroy the Moslems, and then they will turn on you."

He hates the Tartars. I can hear it in his voice, see it in the glow in his eyes. He is sincere enough about that.

A cardinal shouted out something in Latin too rapid for Simon to understand. An archbishop bellowed an answer. Two cardinals were arguing loudly in the pews on the other side of the room. Suddenly all the Church leaders seemed to be talking at once. Fra Tomasso picked up a little bell from his desk and rang it vigorously. Simon could barely hear it, and everyone ignored it.

The princes of the Church quarrel among themselves like ordinary men.

Pope Urban stood up and lifted his arms. "Silence!" he cried. His voice was shrill and louder than Fra Tomasso's bell. The argument died down.

"Have you seen the Tartar army in action, Messer David?" d'Aquino asked.

David was silent a long time before answering. His face took on a haunted look. His eyes seemed to gaze at something far away.

"I was at Baghdad a week after they took it. I came to trade with the Tartars. There were no other people left in that country to trade with. The Tartar camp was many leagues away from the ruins of Baghdad. They had to move away from the city to escape the smell of the dead. I went to Baghdad because I wanted to see. I saw nothing but ashes and corpses for miles and miles. The stink of rotting flesh nearly killed me.

"I found people who had survived. Those who had not gone mad told me what had happened. The Tartars commanded the caliph to surrender. He said he would pay tribute, but he could not surrender his authority to them because he was the spiritual head of Islam."

Simon heard murmurs of derision at this, but David ignored them and, speaking through Ugolini, went on.
