De Pirenne held up a broad hand. "I will slap them down for you, if need be, Monseigneur." Now that a third party was present, he addressed Simon formally.

"Travel is said to open a man's mind," said Friar Mathieu when de Pirenne was gone. "But some minds are like country châteaus. Let anything strange approach, and the doors and windows slam shut."

He took Simon's arm and steered him over the flagstones of the piazza toward the cathedral. The many-columned façade of pink, white, and green marble, sculptures, and mosaics filling the spaces between them took Simon's breath away. There was an opulence to the five great domes that seemed to Simon to speak of the storied wealth of the East. They were so different from the pointed spires of the cathedrals newly built in France.

"I am very grateful to you, Simon, for trying so hard to protect us today," Friar Mathieu said. "The doge's discourtesy to you was the worst kind of rudeness, the rudeness of one who thinks himself more refined than all others."

Simon felt better, but he wondered if the friar was speaking so only out of kindness to him.

"It is good of you to reassure me," he said, "but the doge seems to be guarding the ambassadors well enough."

"All show," said Friar Mathieu. "The Venetians are not alert enough. The doge has no idea that we are in any danger. Nor does he seem to care. I believe he has not decided whether he has anything to gain from an alliance between Christians and Tartars. After all, the Venetians trade quite happily with the Muslims these days."

Simon was shocked. "Is that not a sin?"

"Against God, perhaps, but not against profit. And the common heading on your Venetian merchant's account book is 'For God and Profit.' Young Seigneur de Gobignon, you do not know how happy I am to talk to a Frenchman again after so many years."

"How long have you been among the Tartars, Friar Mathieu?"
