King and Emperor

that those boats out there in the calm bay of Palma would soon be trying to find some unguarded spring or other. No doubt they hoped that he, Ma'mun, would be unable to guard every foot of shore on this rugged island. Now it would be their turn to be mistaken.

As he turned dismissively from the last moments of the destruction of his fleet, he became aware of some disturbance on the outer fringes of his guard. A young man was struggling in the grip of two warriors, calling out angrily. Angrily, not fearfully. Ma'mun signed to his guard-captain to let the young man through. If he had a word to say, let him say it. If he wasted the time of the commander of the faithful, he could go to the impaling-post as a warning to others.

The young man fretfully pulling his clothes back into place had the face of a Qurayshi too, Ma'mun noticed. Most of his army now were the descendants of Berbers, converted Spaniards, even Goths. Ma'mun had been obliged to prohibit taunts of pork-eating, so sensitive were the sons of former Christians in his ranks. But this young man had no touch of the tow-brush about him, as lean and dark-faced as Ma'mun himself. He spoke, too, like a true Arab, without evasion or deference.

“Commander, the men on those ships are not Greeks, even if the ships throw out the Greek fire. Not all of them. Many are ferengis, Franks.”

Ma'mun raised an eyebrow. “How has it been permitted to you to see this? I have not seen it, and my eyes are keen enough to pick out the Rider of the Stars.” He meant the star in Orion's sword-belt which has, invisible to all but the keenest-sighted, a tiny companion sheltered by the light of its neighbor.

The young man smiled with irritating condescension. “I have that which enables me to see better even than that.”

The guard-captain standing at the young man's elbow stepped forward, aware that his master was on the edge of ordering the impaling-post to be set up. “The young man here, lord, is Mu'atiyah. A pupil of bin- Firnas.”

Ma'mun hesitated, pulling his beard. He himself had been named after the great Caliph of fifty years before, who had set up the great library and center of wisdom in Baghdad. He had the greatest respect for men of learning. And there was no doubt that Abu'l Qasim Abbas bin-Firnas was the glory of Cordova for his learning and his many experiments. With less impatience in his voice he said, “Show us then, the wisdom of your master.”

Smiling once more, the young Mu'atiyah pulled from his sleeve an object like a stout bottle covered in leather.

“Know,” he said, “that my master, being advanced in years, found a dimness coming upon his eyes, so that he could see only that which was further away than his own arm's reach. For many years he had studied the science of making glass, and the stones from which it might be made. So, by accident, one day he discovered that if one looked through stones of a certain kind and shape, that which was too close for his eyes became as it were far away, so that he might read it. And, not by accident but by design, he studied many hours till he could find a glass shape that would do likewise for him, and restore to him the liberty of his books.”

“But that is to make the close far away,” replied Ma'mun. “Here we have need of the opposite.”

Again the young man smiled, again provoking Ma'mun with his display of confidence. “That is what I, Mu'atiyah, have discovered. That if one takes not one but two glasses, and looks first through one and then through the other, the far away comes close.”

Thoughtfully, Ma'mun reached over and took the leather object from the young man's hand, disregarding a look of alarm and a sudden babble of explanation. He put it to his eye, looked a moment, lowered it.

“I see only the tiniest of images.”

“Not like that, lord, mighty one.” The young man was at least showing agitation for the first time. It was often so with the learned, Ma'mun conceded grimly. What upset them the most was not the threat of death but the fear that they would not be able to display their abilities. He allowed the young man to take the object from his hand, reverse it so that he looked through what appeared to be the neck.

“Yes, lord. On the deck of the lead ship I see a Greek, with a curled beard, standing by an image of the holy.” Ma'mun's face twisted in disgust, and he spat ritually to avert the contamination created by any image of the divine. “But by him there is a fair-haired Frank, all in metal armor. They are arguing, pointing in different directions.”

“What are they saying?”

“My art deals with sight, not sound.”

“Very well.” Ma'mun signed to the guard-captain. “Take the young man from his place in the ranks, keep him with yourself. If I have need of his art I will send for him. If I do not, the armies of Spain have more need of wise men than of brave ones. We must keep him safe. And, Mu'atiyah, if you tell me where the Greek amiral means to land for water before I can see myself, I will fill your mouth with gold. If you tell me wrong I will melt it first.”

He turned away, calling to his commanders of divisions. Behind him the young man raised his spyglass again, seemed to be attempting to gain a clearer view by moving his eye in and out from the eyepiece.

From time to time in his babbling flow of talk, the Mallorcan villager cast a fearful glance sideways. He had reason to feel fear. The villager had seen the fleet of great red galleys pull round the point, having burned to the waterline the ships that had brought the circumcised to Mallorca long months before. He had realized they must be searching for water, and theorized that whoever they were, the enemies of Muhammad must be his friends. So, when they came ashore and began to set up their camp, and after he had crept close enough to see the crucifixes and the saints' images raised, he had come shyly and slowly forward to volunteer his services: hoping for some reward that might keep him from starvation. Hoping too for revenge on the fierce dark-faced raiders who had stolen from him wife and son and daughters.

Yet he had not reckoned on facing quite such strange and menacing allies. The villager had no language in common with the Greek sailors, or with the German soldiers whom they transported. He had been passed on, though, from guard-post to guard-post till they found a Latin-speaking chaplain. If he spoke slowly and listened carefully, he and the Mallorcan could understand each other, for the Mallorcan's peculiar dialect was no more than the Vulgar Latin of old time, spoken badly and without a schoolmaster for generation after forgotten generation. So much the Mallorcan had expected. He had not expected to find anyone like the man who stood with a scowl on his face next to the Christian priest and his wizened informant.

Agilulf, Ritter of the Lanzenorden, once companion of the great Emperor Bruno himself, and now commander of the expedition against the Moors, stood a foot taller than either priest or villager. His height was increased by the visored iron helmet he wore, and the black plume in it that marked his rank. Yet what the villager could not understand, or hardly believe, was not the man but his dress. From head to foot Agilulf seemed to be made of iron. He wore helmet, mail shirt hanging to his knees, greaves on his calves and beneath them iron-plated boots. Iron studded his gauntlets and rimmed the long kite-shaped shield he carried: a horseman's shield, drawn out in a kite shape to protect the lancer's left leg when he charged, but carried by Agilulf on foot as if weight meant nothing to him. Nor heat. Beneath the iron he wore leather to prevent links being beaten into his flesh, beneath the leather he wore hemp to soak up the sweat. In the late afternoon heat of the Balearics in spring time, the sweat sprang out from under the hairline and dripped steadily down into his beard. He took no notice, as if to notice discomfort was beneath his dignity. To the villager, who had never seen more iron in his life than it would take to sheathe the spike on his primitive plow, the German seemed a creature from another world. The cross painted on his shield was little comfort.

“What does he say?” demanded Agilulf, tiring of listening to slow exchanges in a language he could not follow.

“He says there is a good spring half a mile away, where we could fill as many water-barrels as we wish. But he says the Moslems know of it and use it too. They will have seen us already. The main army of the invaders is a bare ten miles off. They move with the speed of the wind, he says. That is how he lost his family: taken before anyone in his village knew raiders had landed.”

Agilulf nodded. He showed none of the dismay that Pedro the villager had expected. “Does he know how many men the Moslems have?”

The priest shrugged. “He says ten thousand thousand. That could mean anything over a couple of hundred.”

Agilulf nodded again. “Very well. Give him some grain and a flask of wine, and let him go. I expect there are many like him skulking in these hills. Tell him when the Moslems have broken there will be a reward for heads. They
