So the shepherd took the flowers and the seed, and scarcely had he done so when a mighty peal of thunder, followed by the shock of an earthquake, rent the cavern, and when he had collected his senses he found himself once more upon the mountain side.

When he reached home and had told his tale, his wife scolded him roundly for not bringing home a jewel which would have made them rich for ever. But when she would have thrown the flowers away he prevented her. Next day he sowed the seed in his field, and was surprised to find how far it went.

Very soon after this the field was thick with tiny green shoots; and though his wife reproached him for wasting good ground upon useless flowers, he watched and waited in hope until the field was blue with the starry flax blooms.

Then one night, when the flowers had withered and the seed was ripe, Frigga, in the disguise of an old woman, visited the lowly hut and showed the shepherd and his astonished wife how to use the flax stalks; how to spin them into thread, and how to weave the thread into linen.

It was not long before all the dwellers in that part of the earth had heard of the wonderful material, and were hurrying to the shepherd's hut to buy the bleached linen or the seed from which it was obtained.

And so the shepherd and his family were soon among the richest people in the land; and the promise of Frigga was amply fulfilled.

CHAPTER IV

How a Giant Built a Fortress for the Asas

_This is the tale the Northmen tell of how a giant once built a fortress for the Asas._

Although their city of Asgard was beautiful beyond compare, the Asas who lived therein could not forget that the race of the giants kept unwearying watch to do them despite. Even All-Father Odin was troubled when he remembered Mimir's warning that the draught of wisdom would ever work strife between the races of Asas and giants. And so at length the Asas, meeting in their Council Chamber at the roots of the Tree of Life, resolved that something more should be done to guard themselves. Already, it is true, the watchman Heimdall kept ward over the Rainbow Bridge by night and day, blowing a soft note on his horn to announce the coming or going of the Asas, but prepared to give a terrible blast should any of the Frost Giants attempt to cross the bridge.

Heimdall, however, might be overpowered before aid could reach him, and so it was decided to build, just within Asgard, a great fortress, which should be so strong that the Asas could rest safely behind its walls, even if the Frost Giants should invade their city.

The next question was, Who should build this fortress?

None of the Asas knew of a likely architect, and while they were discussing where one should be found, the horn of Heimdall rang out in token of the approach of a stranger.

Out rushed the Asas, and there, in parley with Heimdall, stood a gigantic figure with powerful limbs, on which the muscles stood out like ropes of iron.

Heimdall was speaking sharply, for he did not altogether like the stranger's look. "For what purpose do you come?" he was inquiring.

"I am a Master Builder," replied the stranger. "I can build towers and forts more strongly than any other builder in all the world. Have you anything of the kind that wants doing here?"

The eyes of the Asas met as they heard these words, and Odin, stepping forward, said, "Can you build us a fortress so strong that not all the strength of the Frost Giants could avail against it?"

"Ay, that can I," replied the stranger. "Look at my strong arms and see the breadth of my chest. If you will set me to work you shall soon find my worth as a Master Builder."

"How long will the fortress take to build?" asked Odin.

"I will build it for you in three half years," replied the stranger.

"And what do you ask as wages?" said Odin, and the Master Builder answered promptly:

"You must give me the sun, the moon, and Freya for my wife."

At these words the Asas, who had been pressing forward to hear the conference, fell back with muttered disapproval. For Freya was the most beautiful maiden in Asgard, the joy and pride of the city, ever young and ever fair; and the sun and moon were the light and life of men in the world below. So they bade the Master Builder come again next day, and meantime retired to their Council Hall to consider the matter.

All-Father Odin was for sending the Builder promptly about his business when he returned for their decision, but his brother Loki counselled a different course.

Red Loki was a mischievous, sly fellow, full of wiles and deceit, and always quick to suggest a way out of a difficulty. On this occasion his plan was to allow the man to build the fortress, and to promise him the terms demanded, but subject to the condition that he fulfilled his task in a way that would be impossible for him fully to carry out.

His eloquence persuaded the Asas, and next day, when the Builder returned for their decision, Loki, as their spokesman, called to the mighty fellow as he crossed the bridge:

"Good man, we cannot wait for three half years for the completion of our fortress. But if you will undertake to do the work in the course of one winter, without any a.s.sistance, you shall have Freya, and the sun and moon to boot. If, however, on the first day of summer, one stone is missing from its place, the fortress will be ours without any payment whatever, since you will have broken your plighted word."

At this the Master Builder did not look well pleased. He pulled his great beard and eyed the speaker doubtfully, muttering that the time was too short for so great a task; but when Loki pretended to turn away, as though the matter were ended, he called after him:

"Well, have it so--the fortress shall be built in the time you set.

But you must at least let me have the help of my good horse Svadilfare to carry stone."

When they heard this request the Asas demurred, saying: "He means to play us some trick."

But Loki persuaded them to make this trifling concession.

"For," said he, "of what use can a horse be in building a fortress? He will never be able to finish the place in time, and we shall get our fort for nothing. At least you can let him have his great clumsy horse for any use that he may be."

So the Asas agreed, and went their different ways, leaving the Master Builder to his work.

The winter months pa.s.sed on, and while the Asas busied themselves with their various occupations and amus.e.m.e.nts, the Master Builder was toiling with might and main. But he could have done little in the time if he had not had the help of his wonderful horse Svadilfare, who not only dragged huge blocks of stone to the spot, but raised them into position with his strong forefeet. And this was done with such speed that, some days before the end of winter, the fortress was finished, with the exception of three blocks of stone which were to form one of the gateways.

Then the Asas suddenly realised what was about to happen. In less than three days more the fortress would be finished; it needed, in fact, but one night's work to make all complete. They remembered with horror the price they had undertaken to pay; the loss not only of Freya, fairest of maidens, but also of sun and moon, whose light was the joy of their life and the necessity of mankind.

"It is Red Loki," said they, "who has brought us to this sad pa.s.s." So they began to reproach him very bitterly, threatening even to kill him if he did not find some way to evade the loss which threatened them.

At length, being really frightened, Loki promised to do something--anything, that would prevent the Master Builder from finishing the work during the three days that yet remained of winter.

That same night good Svadilfare was painfully dragging a great block of stone along the path to the new-built fortress, when Red Loki, changed into the semblance of a pretty little grey mare, came running up, saying, as plainly as horses can speak:

"Down below there is a delightful green meadow. Do come with me, and take a holiday from this ever-lasting work."

Scarcely had he heard her neigh when the steed kicked off his harness, left the block of stone to roll down the steep hill, and rushed after the mare. Away ran Loki, away ran Svadilfare, and after them rushed the Master Builder, shouting and yelling in vain. The noise they made was terrific, for the gallop of the horses and the _thud_, _thud_, of the mighty Builder shook the walls of Asgard and made the earth-dwellers shrink in terror from what they imagined to be thunderstorms and earthquakes. But the Builder never found his horse, for Loki had lured him to a meadow hidden safely away within a secret grove.

When the Master Builder returned to the fortress the first day of summer had dawned, and lo! the winter was gone, and the gateway of the building was unfinished.

Before it stood the Asas, and All-Father Odin greeted the Builder with:

"See, fellow, here is the first day of summer and your task is not yet fulfilled. Begone, then, from Asgard, for we are free from our bond, and would have no further dealing with thee or thy evil brood."

Then the Builder perceived that Odin knew who he really was, and with a roar of rage he returned to his own form, and stood revealed as a mighty Frost Giant, almost as huge as the fortress he had built.

Shaking his great fist at the Asas, he shouted threateningly:

"Ye have tricked and fooled me enough. Not for nothing does a Frost Giant stand within the walls of Asgard. Were it not so strongly built I would now tear down this fortress that I have raised; but your own palaces are not giant-built, and see to it that they are not soon tumbling about your ears!"

And in good sooth he might have torn down the very halls of the Asas in his rage, had not Thor at that moment dashed up the Rainbow Bridge in his chariot drawn by goats. For all this while Thor, the strongest of the Asas, had been away on a long journey; and had this not been so, the giants would have had little cause to fear.

Springing from his chariot as the furious giant was about to pull the roof off Valhalla, Thor gave him so mighty a blow on the head with his huge hammer that his skull broke into little bits and his body fell down into the Land of Mists.
