"I am not surprised, knowing Your Reverence's reputation, that you grasp just how important the matter is," Friar Mathieu said.

Neatly sidestepping Fra Tomasso's question, Simon thought.

"Exactly. Thus it was that when Cardinal de Verceuil went to Fra Augustino da Varda, my Superior General, demanding that he order me to change my position on the Tartars, I realized it was time for me to come to a conclusion."

"I made a terrible mistake," said Friar Mathieu as much to himself and Simon as to Fra Tomasso. "May God forgive me."

"What mistake was that?" asked Fra Tomasso.

"Not trying to discuss this with Your Reverence myself, as I am doing now. To be honest, I feared you would not care to meet with a poor Franciscan."

"Again you do me an injustice," said Fra Tomasso. "The philosopher tells us that we acquire knowledge first of all through the senses. Therefore, if you would know about something, ask of those who have seen it firsthand."

"Then perhaps you have new questions," said Friar Mathieu.

Simon felt despair pressing on him like a mail shirt that was too heavy. Fra Tomasso was a man whose whole life was argument. How could Friar Mathieu hope to persuade him to change his mind about anything?

His chair creaking loudly, Fra Tomasso leaned forward and rested his elbows on the table in front of him. "I am so sure of my conclusions that I have written to Emperor Sigismund in Germany, King Boleslav in Poland, and King Wenceslas in Hungary—all lands that have suffered from the depredations of the Tartars, urging them to beg His Holiness to repudiate this scheme that will bring the frontier of Tartary so much closer to us. I have written to King Louis of France, your liege lord, too, young Count de Gobignon, even though he is said to be eager for a pact with the Tartars. Furthermore, Father da Varda is considering my proposal that the Dominican order all over Christendom preach against an alliance with the Tartars."
