It burned in his spirit To urge his folk to found a great building, A mead-hall grander than men of the era Ever had heard of, and in it to share With young and old all of the blessings The Lord had allowed him, save life and retainers. The night of the inauguration of this building, the royal body-guard lay down in the hall to sleep; and, when the servants entered the place on the morrow, they were horrified to find floor and walls spattered with blood, but no other trace of the thirty knights who had rested there the night before. Their cry of horror aroused Hrothgar, who, on investigating, discovered gigantic footsteps leading straight from the hall to the sluggish waters of a mountain tarn, above which a phosphorescent light always hovered. These footsteps were those of Grendel, a descendant of Cain, who dwelt in the marsh, and who had evidently slain and devoured all the king's men. Too old to wield a sword in person, Hrothgar offered a princely reward to whoever would rid his country of this terrible scourge. But, although many warriors gladly undertook the task, the monster proved too strong for all, and none save a minstrel--who hid in one corner of the hall--ever succeeded in escaping from his clutches. This minstrel, after seeing Grendel feed upon his companions, was so impressed by the sight, that he composed a song about it, which he sang wherever he went, and once repeated for the entertainment of King Higelac and his nephew Beowulf. In answer to their eager questions, the bard averred the monster still existed and invariably invaded the hall when a feast was held there. This was enough to arouse in Beowulf a burning desire to visit Denmark and rid the world of this scourge. Knowing his nephew was very brave and having had proof of his endurance (for the young man had once in the course of a swimming match, stayed in the water five whole days and nights, killing many sea monsters who came to attack him), Higelac gladly allowed him to depart with fourteen chosen companions. Thus Beowulf set out "over the Swan-Road" for Denmark, to offer his services to the king. The foamy-necked floater fanned by the breeze, Likest a bird, glided the waters, Till twenty and four hours thereafter The twist-stemmed vessel had travelled such distance That the sailing-men saw the sloping embankments, The sea-cliffs gleaming, precipitous mountains, Nesses enormous: they were nearing the limits At the end of the ocean.
