“That priest is twisty as a serpent,” Da’ud ibn Zubayr whispered to Jalal ad-Din. The older man nodded, frowning. He was not quite sure how to respond to Theodore’s latest sally. Who was he to say what Allah could or could not do?

Telerikh roused him from his unprofitable reverie by asking, “So you Arabs deny Jesus is the son of your one god, eh?”

“We do,” Jalal ad-Din said firmly.

“What do you make of him, then?” the khan said.

“Allah commands us to worship none but himself, so how can he have a son? Jesus was a holy man and a prophet, but nothing more. Since the Christians corrupted his words, Allah inspired Muhammad to recite the truth once more.”

“Could a prophet rise from the dead on the third day, as God’s Son did?” Theodore snorted, clapping a dramatic hand to his forehead. “Christ’s miracles are witnessed and attested in writing. What miracles did Muhammad work? None, the reason being that he could not.”

“He flew to Jerusalem in the course of a night,” Jalal ad-Din returned, “as the Qu’ran records-in writing,” he added pointedly. “And the crucifixion and resurrection are fables. No man can rise from the dead, and another was set on the cross in place of Jesus.”

“Satan waits for you in hell, blasphemer,” Theodore warned. “Christ healed the sick, raised the dead, stopped wind and rain in their tracks. Anyone who denies him loses all hope of heaven, and may garner for his sin only eternal torment.”

“No, that is the fate reserved for those who make one into three,” Jalal ad-Din said. “You-”

“Wait, both of you.” Telerikh held up a hand. The Bulgar khan, Jalal ad-Din thought, seemed more stunned than edified by the arguments he had heard. The Arab realized he had been quarreling with Theodore rather than instructing the khan. Telerikh went on. “I cannot find the truth in what you are saying, for each of you and each of your books makes the other a liar. That helps me not at all. Tell me instead what I and my people must do if we follow one faith or the other.”

“If you choose the Arabs’ false creed, you will have to abandon both drinking wine and eating pork,” Theodore said before Jalal ad-Din could reply.”Let him deny it if he may.” The priest shot the Arab a triumphant look.

“It is true,” Jalal ad-Din said stoutly. “Allah has ordained it.”

He tried to put a bold face on it, but knew Theodore had landed a telling blow. The mutter that went up from Telerikh’s boyars confirmed it. A passion for wine inflamed most nonbelievers, Jalal ad-Din thought; sadly, despite the good counsel of the Qu’ran, it could capture Muslims as well. And as for pork-judging from the meals they served at Pliska, the Bulgars found it their favorite flesh.

“That is not good,” Telerikh said, and the Arab’s heart sank.

A passion for wine… passion! “Magnificent khan, may I ask without offense how many wives you enjoy?”

Telerikh frowned. “I am not quite sure. How many is it now, Dragomir?”

“Forty-seven, mighty khan,” the steward replied at once, competent as usual.

“And your boyars?” Jalal ad-Din went on. “Surely they also have more than one apiece.”

“Well, what of it?” the khan said, sounding puzzled.

Now Jalal ad-Din grinned an unpleasant grin at Theodore. “If you become a Christian, magnificent khan, you will have to give up all your wives save one. You will not even be able to keep the others as concubines, for the Christians also forbid that practice.”

“What?” If Telerikh had frowned before, the scowl he turned on the Christians now was thunderous. “Can this be true?”

“Of course it is true,” Theodore said, scowling back. “Bigamy is a monstrous sin.”

“Gently, my brother in Christ, gently,” Paul said. “We do not wish to press too hard upon our Bulgar friends, who, after all, will be newly come to our observances.”

“That one is truly a nuisance,” Da’ud whispered.

“You are too right,” Jalal ad-Din whispered back.

“Still, excellent khan,” Paul went on, “you must not doubt that Theodore is correct. When you and your people accept Christianity, all those with more than one wife-or women with more than one husband, if any there be-will be required to repudiate all but their first marriages and to undergo penance under the supervision of a priest.”

His easy, matter-of-fact manner seemed to calm Telerikh. “I see you believe this to be necessary,” the khan said. “It is so strange, though, that I do not see why. Explain further, if you will.”

Jalal ad-Din made a fist. He had expected Christian ideas of marriage to appall Telerikh, not to intrigue him with their very alienness. Was a potential monk lurking under those fur robes, under that turban?

Paul said, “Celibacy, excellent khan, is the highest ideal. For those who cannot achieve it, marriage to a single partner is an acceptable alternative. Surely you must know, excellent khan, how lust can inflame men. And no sin is so intolerable to prophets and other holy men as depravity and sexual license, for the Holy Spirit will not touch the heart of a prophet while he is engaged in an erotic act. The life of the mind is nobler than that of the body; on this Holy Scripture and the wise ancient Aristotle agree.”

“I never heard of this, ah, Aristotle. Was he a shaman?” Telerikh asked.

“You might say so,” Paul replied, which impressed Jalal ad-Din. The Arab knew little of Aristotle, hardly more than that he had been a sage before even Roman times. He was certain, however, that Aristotle had been a civilized man, not a barbarous pagan priest. But that was surely the closest equivalent to sage within Telerikh’s mental horizon, and Paul deserved credit for recognizing it.

The Bulgar khan turned to Jalal ad-Din. “What have you to say about this?”

“The Qu’ran permits a man four lawful wives, for those able to treat them equally well,” Jalal ad-Din said. “For those who cannot, it enjoins only one. But it does not prohibit concubines.”

“That is better,” the khan said. “A man would get bored, bedding the same woman night after night. But this business of no pork and no wine is almost as gloomy.” He gave his attention back to the priests. “You Christians allow these things.”

“Yes, excellent khan, we do,” Paul said.

“Hmm.” Telerikh rubbed his chin. Jalal ad-Din did his best to hide his worry. The matter still stood balanced, and he had used his strongest weapon to incline the khan to Islam. If the Christians had any good arguments left, he-and the fate of the true faith in Bulgaria-were in trouble.

Paul said, “Excellent khan, these matters of practice may seem important to you, but in fact they are superficial. Here is the key difference between the Arab’s faith and ours: the religion Muhammad preached is one that loves violence, not peace. Such teaching can only come from Satan, I fear.”

“That is a foul, stinking lie!” Da’ud ibn Zubayr cried. The other two Arabs behind Jalal ad-Din also shouted angrily.

“Silence!” Telerikh said, glaring at them. “Do not interrupt. I shall give you a chance to answer in due course.”

“Yes, let the Christian go on,” Jalal ad-Din agreed. “I am sure the khan will be fascinated by what he has to say.”

Glancing back, he thought Da’ud about to burst with fury. The younger man finally forced out a strangled whisper: “Have you gone mad, to stand by while this infidel slanders the Prophet (may blessings be upon his head)?”

“I think not. Now be still, as Telerikh said. My ears are not what they once were; I cannot listen to you and Paul at once.”

The monk was saying, “Muhammad’s creed urges conversion by the sword, not by reason. Does not his holy book, if one may dignify it by that tide, preach the holy war, the jihad”-he dropped the Arabic word into his polished Greek- “against all those who do not share his faith? And those who are slain in their murderous work, says the false prophet, attain to heaven straightaway.” He turned to Jalal ad-Din. “Do you deny this?”
