Not only did he know all the actual sciences, but the black arts as well, and magic, and what not. He conjured demons so that when a body passed the house of a moonlight night a body might see imps, great and small, little and big, sitting on the chimney stacks and the ridge-pole, clattering their heels on the tiles and chatting together.

He could change iron and lead into silver and gold; he discovered the elixir of life, and might have been living even to this day had he thought it worth while to do so.

There was a student at the university whose name was Gebhart, who was so well acquainted with algebra and geometry that he could tell at a single glance how many drops of water there were in a bottle of wine. As for Latin and Greek—he could patter them off like his A B C’s. Nevertheless, he was not satisfied with the things he knew, but was for learning the things that no schools could teach him. So one day he came knocking at Nicholas Flamel’s door.

“Come in,” said the wise man, and there Gebhart found him sitting in the midst of his books and bottles and diagrams and dust and chemicals and cobwebs, making strange figures upon the table with jackstraws and a piece of chalk—for your true wise man can squeeze more learning out of jackstraws and a piece of chalk than we common folk can get out of all the books in the world.

No one else was in the room but the wise man’s servant, whose name was Babette.

“What is it you want?” said the wise man, looking at Gebhart over the rim of his spectacles.

“Master,” said Gebhart, “I have studied day after day at the university, and from early in the morning until late at night, so that my head has hummed and my eyes were sore, yet I have not learned those things that I wish most of all to know—the arts that no one but you can teach. Will you take me as your pupil?”

The wise man shook his head.

“Many would like to be as wise as that,” said he, “and few there be who can become so. Now tell me. Suppose all the riches of the world were offered to you, would you rather be wise?”

“Yes.”

“Suppose you might have all the rank and power of a king or of an emperor, would you rather be wise?”

“Yes.”

“Suppose I undertook to teach you, would you give up everything of joy and of pleasure to follow me?”

“Yes.”

“Perhaps you are hungry,” said the master.

“Yes,” said the student, “I am.”

“Then, Babette, you may bring some bread and cheese.”

It seemed to Gebhart that he had learned all that Nicholas Flamel had to teach him.

It was in the gray of the dawning, and the master took the pupil by the hand and led him up the rickety stairs to the roof of the house, where nothing was to be seen but gray sky, high roofs, and chimney stacks from which the smoke rose straight into the still air.

“Now,” said the master, “I have taught you nearly all of the science that I know, and the time has come to show you the wonderful thing that has been waiting for us from the beginning when time was. You have given up wealth and the world and pleasure and joy and love for the sake of wisdom. Now, then, comes the last test—whether you can remain faithful to me to the end; if you fail in it, all is lost that you have gained.”

After he had said that he stripped his cloak away from his shoulders and laid bare the skin. Then he took a bottle of red liquor and began bathing his shoulder-blades with it; and as Gebhart, squatting upon the ridge-pole, looked, he saw two little lumps bud out upon the smooth skin, and then grow and grow and grow until they became two great wings as white as snow.

“Now then,” said the master, “take me by the belt and grip fast, for there is a long, long journey before us, and if you should lose your head and let go your hold you will fall and be dashed to pieces.”

Then he spread the two great wings, and away he flew as fast as the wind, with Gebhart hanging to his belt.

Over hills, over dales, over mountains, over moors he flew, with the brown earth lying so far below that horses and cows looked like pismires and men like fleas.

Then, by-and-by, it was over the ocean they were crossing, with the great ships that pitched and tossed below looking like chips in a puddle in rainy weather.

At last they came to a strange land, far, far away, and there the master lit upon a sea-shore where the sand was as white as silver. As soon as his feet touched the hard ground the great wings were gone like a puff of smoke, and the wise man walked like any other body.

At the edge of the sandy beach was a great, high, naked cliff; and the only way of reaching the top was by a flight of stone steps, as slippery as glass, cut in the solid rock.

The wise man led the way, and the student followed close at his heels, every now and then slipping and stumbling so that, had it not been for the help that the master gave him, he would have fallen more than once and have been dashed to pieces upon the rocks below.

At last they reached the top, and there found themselves in a desert, without stick of wood or blade of grass, but only gray stones and skulls and bones bleaching in the sun.

In the middle of the plain was a castle such as the eyes of man never saw before, for it was built all of crystal from roof to cellar. Around it was a high wall of steel, and in the wall were seven gates of polished brass.

The wise man led the way straight to the middle gate of the seven, where there hung a horn of pure silver, which he set to his lips. He blew a blast so loud and shrill that it made Gebhart’s ears tingle. In an instant there sounded a great rumble and grumble like the noise of loud thunder, and the gates of brass swung slowly back, as though of themselves.

But when Gebhart saw what he saw within the gates his heart crumbled away for fear, and his knees knocked together; for there, in the very middle of the way, stood a monstrous, hideous dragon, that blew out flames and clouds of smoke from his gaping mouth like a chimney a-fire.

But the wise master was as cool as smooth water; he thrust his hand into the bosom of his jacket and drew forth a little black box, which he flung straight into the gaping mouth.

Snap!—the dragon swallowed the box.

The next moment it gave a great, loud, terrible cry, and, clapping and rattling its wings, leaped into the air and flew away, bellowing like a bull.

If Gebhart had been wonder-struck at seeing the outside of the castle, he was ten thousand times more amazed to see the inside thereof. For, as the master led the way and he followed, he passed through four-and-twenty rooms, each one more wonderful than the other. Everywhere was gold and silver and dazzling jewels that glistened so brightly that one had to shut one’s eyes to their sparkle. Beside all this, there were silks and satins and velvets and laces and crystal and ebony and sandal-wood that smelled sweeter than musk and rose leaves. All the wealth of the world brought together into one place could not make such riches as Gebhart saw with his two eyes in these four-and-twenty rooms. His heart beat fast within him.

At last they reached a little door of solid iron, beside which hung a sword with a blade that shone like lightning. The master took the sword in one hand and laid the other upon the latch of the door. Then he turned to Gebhart and spoke for the first time since they had started upon their long journey.

“In this room,” said he, “you will see a strange thing happen, and in a little while I shall be as one dead. As soon as that comes to pass, go you straightway through to the room beyond, where you will find upon a marble table a goblet of water and a silver dagger. Touch nothing else, and look at nothing else, for if you do all will be lost to both of us. Bring the water straightway, and sprinkle my face with it, and when that is done you and I will be the wisest and greatest men that ever lived, for I will make you equal to myself in all that I know. So now swear to do what I have just bid you, and not turn aside a hair’s breadth in the going and the coming.”

“I swear,” said Gebhart, and crossed his heart.

Then the master opened the door and entered, with Gebhart close at his heels.

In the center of the room was a great red cock, with eyes that shone like sparks of fire. So soon as he saw the master he flew at him, screaming fearfully, and spitting out darts of fire that blazed and sparkled like lightning.

It was a dreadful battle between the master and the cock. Up and down they fought, and here and there. Sometimes the student could see the wise man whirling and striking with his sword; and then again he would be hidden in a sheet of flame. But after a while he made a lucky stroke, and off flew the cock’s head.
