canât be,â Gerbert said. âSorcery is evil. God forbids it.â
âSorcery,â said Ibrahim, âyes. I am not a sorcerer.â
âBut isnât it all the same?â
âHardly.â Ibrahim straightened and tucked up his feet. He had a look which Gerbert knew well: eager, intent. A teacherâs look. âMagic has its orders and its divisions, as does any other branch of learning. Most simply, there are three: the white and the black, and the broad realm between. In the learned magic, the distinction lies somewhat in method, but chiefly in purpose. To heal is of the light; to destroy is of the dark.â
âLike prayers and curses.â
Ibrahim nodded, pleased. âVery like. But a prayer beseeches the aid of a saint or of God Himself; it cannot compel. The will of the one who prays is subject to the will of divinity. A white spell differs. It does not presume to command God, Who is above all compulsion. Yet it seeks to work the mageâs will on the powers of heaven and earth. The magus masters them; he shapes them to his ends.â
âHow can that be anything but evil? It goes against the law of God.â
âGodâs law ordains that a spell worked in His name be fulfilled by His will.â
Gerbert frowned. âI donât see... Itâs arrogant. To assume that one knows what He intends.â
âAny of His priests assumes exactly that, in everything he does.â
Gerbertâs frown deepened. The man was right, damn him. And Gerbert should have seen it. And yet... âWhy then do they bid us shun all works of magic?â
âFear,â answered Ibrahim. âIgnorance. Confusion of the high learned Art with its black shadow. The power in itself is neither good nor evil; it simply is. The mind of the magus shapes its purpose.â He paused, a breath only. âI have heard that in your country the same fear and ignoranee have banned the arts of the Quadrivium.â
âNot banned them,â Gerbert said. âLet them slide into neglect. But numbers canât call up devils.â
âCan they not? The art magic grounds itself in the seven liberal arts. The three arts of language and its use; the four sciences. It is all one in the face of God.â
Gerbertâs head shook of itself. âNo. No, it canât be that simple. Or â or that beautiful.â
âWhy should it not be? It is part of Godâs creation. He has not given it to every man, that is true; it is too strong for that, and too perilous. So likewise is any knowledge. In the wrong hands, even the words we speak can destroy a reputation or a life.â
âSurely something must be safe,â Gerbert said.
âSilence. Perhaps. The mute existence of the beast.â
Gerbert shuddered. âGod save me from that. And from the snares of the devil.â
âMay He favor your prayer.â
Gerbert looked at Ibrahim. His eyes, he knew, were wild. âYou believe in Him.â
The magus bowed his head. âI am the lowest of His servants.â
âBut,â said Gerbert. âBut itâs â not â â He had risen without knowing it. âHow can they all have lied to me?â
âThey did not know.â
âGod in heaven!â Gerbert spun about. The words were in his mind: Get thee behind me, Satan! But he had a little sense left. He did not say them. He managed a travesty of a bow, a babble that passed for farewell. The sun was fierce on his throbbing head, the city a blessed, numbing clamor. Blessed because it was simple, human earth. Because there was no magic in it.

Any sensible Christian would have taken refuge in the cathedral, or in any shrine or chapel in a city full of them. Gerbert came to himself down by the quays, in the shadow of the Mount of the Jews. His back was to the city; his face was to the blue splendor of the sea. A ship disgorged treasures out of the east, its master
