I gave only one look at the aged grandmother: wrinkled, bony, hunched, almost bald, toothlessly champing her granulated lips, her eyes red and gummy, her withered paps flapping against slatted ribs. One look at the crone was enough for me. But her daughter, the Shahryar Zahd Mirza, was an exceptionally handsome woman, anyway when she was not talking, and her daughter was a superbly beautiful and shapely girl about my own age. She was the Crown Princess or Shahzrad, and named Magas, which means Moth, and subtitled with the royal Mirza. I have neglected to say that the Persians are not, like Arabs, of dark and muddy complexion. Though they all have blue-black hair, and the men wear blue-black beards like Uncle Mafio’s, their skin is as fair as any Venetian’s, and many have eyes of lighter color than brown. The Shahzrad Magas Mirza was at that moment taking my measure with eyes of emerald green.

“Speaking of horses,” said the Shah, seizing on the tail of the flying-horse tale, before his wife could be reminded of some other story. “You gentlemen should consider trading your horses for camels before you leave Baghdad. Eastward of here you must cross the Dasht-e-Kavir, a vast and terrible desert. Horses cannot endure the—”

“The Mongols’ horses did,” his wife sharply contradicted him. “A Mongol goes everywhere on a horse, and no Mongol would ever bestride a camel. I will tell you how they despise and mistreat camels. While they were besieging this city, the Mongols captured a herd of camels somewhere, and they loaded them with bales of dry grass, and set that hay afire, and stampeded the poor beasts into our streets. The camels, their own fur and humps of fat burning as well, ran mad in agony and could not be caught. So they careered up and down our streets, setting fire to much of Baghdad, before the flames ate into them and reached their vitals, and they collapsed and died.”

“Or,” said the Shah to us, when the Shahryar paused to take a breath, “your journey could be much shortened if you went part way by sea. You might wish to go southeast from here, to Basra—or even farther down the Gulf, to Hormuz—and take passage on some ship sailing to India.”

“In Hormuz,” said the Shahryar Zahd, “every man has only a thumb and the two outer fingers on his right hand. I will tell you why. That seaport city has for ages treasured its importance and its independence, so its every adult male citizen has always been trained as an archer to defend it. When the Mongols under the Ilkhan Hulagu laid seige to Hormuz, the Ilkhan made an offer to the city fathers. Hulagu said he would let Hormuz stand, and retain its independence, and keep its citizen archers, if only the city fathers would lend him those bowmen for long enough to help him conquer Baghdad. Then, he promised, he would let the men come home to Hormuz and be its staunch defense again. The city fathers agreed to that proposal, and all its men—however reluctantly—joined Hulagu in his siege of this city, and fought well for him, and eventually our beloved Baghdad fell.”

She and the Shah both sighed deeply.

“Well,” she went on, “Hulagu had been so impressed by the valor and prowess of the Hormuz men that he then sent them to bed with all the young Mongol women who always accompany the Mongol armies. Hulagu wished to add the potency of the Hormuz seed to the Mongol birthlines, you see. After a few nights of that enforced cohabitation, when Hulagu presumed his females had been sufficiently impregnated, he kept his promise and freed the archers to go home to Hormuz. But before he let them depart, he had every man’s two bowstring fingers amputated. In effect, Hulagu took the fruit from the trees and then felled the trees. Those mutilated men could make no defense of Hormuz at all, and of course that city soon became, like our dear defeated Baghdad, a possession of the Mongol Khanate.”

“My dear,” said the Shah, looking flustered. “These gentlemen are emissaries of that Khanate. The letter they showed me is a ferman from the Khakhan Kubilai himself. I very much doubt that they are amused to hear tales of the Mongols’—er—misbehavior.”

“Oh, you can freely say atrocities, Shah Zaman,” my uncle boomed heartily. “We are still Venetians, not adoptive Mongols nor apologists for them.”

“Then I should tell you,” said the Shahryar, again leaning eagerly forward, “the ghastly way Hulagu treated our Qalif al-Mustasim Billah, the holiest man of Islam.” The Shah breathed another sigh, and fixed his gaze on a remote corner of the room. “As perhaps you know, Mirza Polo, Baghdad was to Islam what Rome is to Christianity. And the Qalif of Baghdad was to Muslims what your Pope is to you Christians. So, when Hulagu laid siege here, it was to the Qalif Mustasim that he proposed surrender terms, not to the Shah Zaman.” She flicked a disparaging glance at her husband. “Hulagu offered to lift the siege if the Qalif acceded to certain demands, among them the handing over of much gold. The Qalif refused, saying, ‘Our gold sustains our Holy Islam.’ And the reigning Shah did not overrule that decision.”

“How could I?” that Shah said weakly, as if it was an argument much argued previously. “The spiritual leader outranks the temporal.”

His wife went implacably on. “Baghdad might have withstood the Mongols and their Hormuz allies, but it could not withstand the hunger imposed by a siege. Our people ate everything edible, even the city rats, but the people got weaker and weaker, and many died and the rest could fight no longer. When the city inevitably fell, Hulagu imprisoned the Qalif Mustasim in solitary confinement, and let him get even hungrier. At last the holy old man had to beg for food. Hulagu with his own hands gave him a plate full of gold coins, and the Qalif whimpered, ‘No man can eat gold.’ And Hulagu said, ‘You called it sustenance when I asked for it. Did it sustain your holy city? Pray, then, that it will sustain you.’ And he had the gold melted, and he poured that glowing-hot liquid metal down the old man’s throat, killing him horribly. Mustasim was the last of the Qalifate, which had endured for more than five hundred years, and Baghdad is no longer the capital either of Persia or of Islam.”

We dutifully shook our heads in commiseration, which encouraged the Shahryar to add:

“As an illustration of how low the Shahnate has been brought: this my husband, Shah Zaman, who was once Shahinshah of all the Empire of Persia, is now a pigeon keeper and cherry picker!”

“My dear … ,” said the Shah.

“It is true. One of the lesser Khans—somewhere to the eastward; we have never even met this Ilkhan—has a taste for ripe cherries. He is also a fancier of pigeons, and his pigeons are trained always to fly home to him from wherever they may be transported. So there are now some hundred of those feathered rats in a dovecote behind the palace stables, and for each there is a tiny silken bag. My Emperor husband has instructions. Next summer when our orchards ripen, we are to pick the cherries, put one or two of them into each of those little bags, fasten the bags to the legs of the pigeons and let the birds free. Like the rukh bird carrying off men and lions and princesses, the pigeons will carry our cherries to the waiting Ilkhan. If we do not pay that humiliating tribute, he will doubtless come rampaging from out of the east and lay our city waste again.”

“My dear, I am sure the gentlemen are now weary of—of traveling hither,” said the Shah, sounding weary himself. He struck the gong to summon the wazir once more, and said to us, “You will wish to rest and refresh yourselves. Then, if you will do me the honor, we will foregather again at the evening meal.”

The wazir, a middle-aged and melancholy man named Jamshid, showed us to our chambers, a suite of three rooms with doors between. They were well furnished, with many qali on the floors and walls, and windows of stone tracery inset with glass, and soft beds of quilts and pillows. Our packs had already been removed from our horses and brought there.
