Siegfried was born a Prince and grew to be a hero, a hero with a heart of gold. Though he could fight, and was as strong as any lion, yet he could love too and be as gentle as a child.
The father and mother of the hero-boy lived in a strong castle near the banks of the great Rhine river. Siegmund, his father, was a rich king, Sieglinde, his mother, a beautiful queen, and dearly did they love their little son Siegfried.
The courtiers and the high-born maidens who dwelt in the castle honoured the little Prince, and thought him the fairest child in all the land, as indeed he was.
Sieglinde, his queen-mother, would ofttimes dress her little son in costly garments and lead him by the hand before the proud, strong men-  at-arms who stood before the castle walls. Nought had they but smiles and gentle words for their little Prince.
When he grew older, Siegfried would ride into the country, yet always would he be attended by King Siegmund's most trusted warriors.
Then one day armed men entered the Netherlands, the country over which King Siegmund ruled, and the little Prince was sent away from the castle, lest by any evil chance he should fall into the hands of the foe.
Siegfried was hidden away safe in the thickets of a great forest, and dwelt there under the care of a blacksmith, named Mimer.
Mimer was a dwarf, belonging to a strange race of little folk called Nibelungs. The Nibelungs lived for the most part in a dark little town beneath the ground. Nibelheim was the name of this little town and many of the tiny men who dwelt there were smiths. All the livelong day they would hammer on their little anvils, but all through the long night they would dance and play with tiny little Nibelung women.
 It was not in the little dark town of Nibelheim that Mimer had his forge, but under the trees of the great forest to which Siegfried had been sent.
As Mimer or his pupils wielded their tools the wild beasts would start from their lair, and the swift birds would wing their flight through the mazes of the wood, lest danger lay in those heavy, resounding strokes.
But Siegfried, the hero-boy, would laugh for glee, and seizing the heaviest hammer he could see he would swing it with such force upon the anvil that it would be splintered into a thousand pieces.
Then Mimer the blacksmith would scold the lad, who was now the strongest of all the lads under his care; but little heeding his rebukes, Siegfried would fling himself merrily out of the smithy and hasten with great strides into the gladsome wood. For now the Prince was growing a big lad, and his strength was even as the strength of ten.
To-day Siegfried was in a merry mood. He would repay Mimer's rebukes in right good fashion. He would frighten the little black-  smith dwarf until he was forced to cry for mercy.
Clad in his forest dress of deerskins, with his hair as burnished gold blowing around his shoulders, Siegfried wandered away into the depths of the woodland.
There he seized the silver horn which hung from his girdle and raised it to his lips. A long, clear note he blew, and ere the sound had died away the boy saw a sight which pleased him well. Here was good prey indeed! A bear, a great big shaggy bear was peering at him out of a bush, and as he gazed the beast opened its jaws and growled, a fierce and angry growl.
Not a whit afraid was Siegfried. Quick as lightning he had caught the great creature in his arms, and ere it could turn upon him, it was muzzled, and was being led quietly along toward the smithy.
Mimer was busy at his forge sharpening a sword when Siegfried reached the doorway.
At the sound of laughter the little dwarf raised his head. It was the Prince who laughed. Then Mimer saw the bear, and letting the  sword he held drop to the ground with a clang, he ran to hide himself in the darkest corner of the smithy.
Then Mimer saw the bear
Then Siegfried laughed again. He was no hero-boy to-day, for next he made the big bear hunt the little Nibelung dwarf from corner to corner, nor could the frightened little man escape or hide himself in darkness. Again and again as he crouched in a shadowed corner, Siegfried would stir up the embers of the forge until all the smithy was lighted with a ruddy glow.
At length the Prince tired of his game, and unmuzzling the bear he chased the bewildered beast back into the shelter of the woodlands.
Mimer, poor little dwarf, all a-tremble with his fear, cried angrily, "Thou mayest go shoot if so it please thee, and bring home thy dead prey. Dead bears thou mayest bring hither if thou wilt, but live bears shalt thou leave to crouch in their lair or to roam through the forest." But Siegfried, the naughty Prince, only laughed at the little Nibelung's frightened face and harsh, croaking voice.
 Now as the days passed, Mimer the blacksmith began to wish that Siegfried had never come to dwell with him in his smithy. The Prince was growing too strong, too brave to please the little dwarf, moreover many were the mischievous tricks his pupil played on him.
Prince though he was, Mimer would see if he could not get rid of his tormentor. For indeed though, as I have told you, Siegfried had a heart of gold, at this time the gold seemed to have grown dim and tarnished. Perhaps that was because the Prince had learned to distrust and to dislike, nay, more, to hate the little, cunning dwarf.
However that may be, it is certain that Siegfried played many pranks upon the little Nibelung, and he, Mimer, determined to get rid of the quick-tempered, strong-handed Prince.
One day, therefore, it happened that the little dwarf told Siegfried to go deep into the forest to bring home charcoal for the forge. And this Mimer did, though he knew that in the very part of the forest to which he was sending the lad there dwelt a terrible dragon, named Regin.  Indeed Regin was a brother of the little blacksmith, and would be lying in wait for the Prince. It would be but the work of a moment for the monster to seize the lad and greedily to devour him.
To Siegfried it was always joy to wander afar through the woodland. Ofttimes had he thrown himself down on the soft, moss-covered ground and lain there hour after hour, listening to the wood-birds' song. Sometimes he would even find a reed and try to pipe a tune as sweet as did the birds, but that was all in vain, as the lad soon found. No tiny songster would linger to hearken to the shrill piping of his grassy reed, and the Prince himself was soon ready to fling it far away.
It was no hardship then to Siegfried to leave the forge and the hated little Nibelung, therefore it was that with right good-will he set out in search of charcoal for Mimer the blacksmith.
As he loitered there where the trees grew thickest, Siegfried took his horn and blew it lustily. If he could not pipe on a grassy reed, at least he could blow a rousing note on his silver horn.
 Suddenly as Siegfried blew, the trees seemed to sway, the earth to give out fire. Regin, the dragon, had roused himself at the blast, and was even now drawing near to the Prince.
It was at the mighty strides of the monster that the trees had seemed to tremble, it was as he opened his terrible jaws that the earth had seemed to belch out fire.
For a little while Siegfried watched the dragon in silence. Then he laughed aloud, and a brave, gay laugh it was. Alone in the forest, with a sword buckled to his side, the hero was afraid of naught, not even of Regin. The ugly monster was sitting now on a little hillock, looking down upon the lad, his victim as he thought.
Then Siegfried called boldly to the dragon, "I will kill thee, for in truth thou art an ugly monster."
"I will kill thee, for in truth thou art an ugly monster"
At those words Regin opened his great jaws, and showed his terrible fangs. Yet still the boy Prince mocked at the hideous dragon.
And now Regin in his fury crept closer and closer to the lad, swinging his great tail, until he well-nigh swept Siegfried from his feet.
 Swiftly then the Prince drew his sword, well tempered as he knew, for had not he himself wrought it in the forge of Mimer the blacksmith? Swiftly he drew his sword, and with one bound he sprang upon the dragon's back, and as he reared himself, down came the hero's shining sword and pierced into the very heart of the monster. Thus as Siegfried leaped nimbly to the ground, the dragon fell back dead. Regin was no longer to be feared.
Then Siegfried did a curious thing. He had heard the little Nibelung men who came to the smithy to talk with Mimer, he had heard them say that whoever should bathe in the blood of Regin the dragon would henceforth be safe from every foe. For his skin would grow so tough and horny that it would be to him as an armour through which no sword or spear could ever pierce.
Thinking of the little Nibelungs' harsh voices and wrinkled little faces, as they had sat talking thus around Mimer's glowing forge, Siegfried now flung aside his deerskin dress and bathed himself from top to toe in the dragon's blood.
But as he bathed, a leaf from off a linden tree  was blown upon his shoulders, and on the spot where it rested Siegfried's skin was still soft and tender as when he was a little child. It was only a tiny spot which was covered by the linden leaf, but should a spear thrust, or an arrow pierce that tiny spot, Siegfried would be wounded as easily as any other man.
The dragon was dead, the bath was over, and clad once more in his deerskin, Siegfried set out for the smithy. He brought no charcoal for the forge; all that he carried with him was a heart afire with anger, a sword quivering to take the life of the Nibelung, Mimer.
For now Siegfried knew that the dwarf had wished to send him forth to death, when he bade him go seek charcoal in the depths of the forest.
Into the dusky glow of the smithy plunged the hero, and swiftly he slew the traitor Mimer. Then gaily, for he had but slain evil ones of whom the world was well rid, then gaily Siegfried fared through the forest in quest of adventure.
