Then they follow up the slot and come to a great water-side, and find thereby Aeschere's head, and the place is known for the lair of those two: monsters are playing in the deep, and Beowulf shoots one of them to death. Then Beowulf dights him and leaps into the water, and is a day's while reaching the bottom. There he is straightway caught hold of by Grendel's Mother, who bears him into her hall. When he gets free he falls on her, but the edge of the sword Hrunting (lent to him by Unferth) fails him, and she casts him to the ground and draws her sax to slay him; but he rises up, and sees an old sword of the giants hanging on the wall; he takes it and smites off her head therewith. He sees Grendel lying dead, and his head also he strikes off; but the blade of the sword is molten in his venomous blood. Then Beowulf strikes upward, taking with him the head of Grendel and the hilts of the sword. When he comes to the shore he finds his Geats there alone; for the Danes fled when they saw the blood floating in the water. They go up to Hrothgar's stead, and four men must needs bear the head. They come to Hrothgar, and Beowulf gives him the hilts and tells him what he has done. Much praise is given to Beowulf; and they feast together. On the morrow Beowulf bids farewell to Hrothgar, more gifts are given, and messages are sent to Hygelac: Beowulf departs with the full love of Hrothgar. The Geats come to their ship and reward the ship-warder, and put off and sail to their own land. Beowulf comes to Hygelac's house. Hygelac is told of, and his wife Hygd, and her good conditions, against whom is set as a warning the evil Queen Thrytho. Beowulf tells all the tale of his doings in full to Hygelac, and gives him his gifts, and the precious-gemmed collar to Hygd. Here is told of Beowulf, and how he was contemned in his youth, and is now grown so renowned. Time wears; Hygelac is slain in battle; Heardred, his son, reigns in his stead, he is slain by the Swedes, and Beowulf is made king. When he is grown old, and has been king for fifty years, come new tidings. A great dragon finds on the sea-shore a mound wherein is stored the treasure of ancient folk departed. The said dragon abides there, and broods the gold for 300 years. Now a certain thrall, who had misdone against his lord and was fleeing from his wrath, haps on the said treasure and takes a cup thence, which he brings to his lord to appease his wrath. The Worm waketh, and findeth his treasure lessened, but can find no man who hath done the deed. Therefore he turns on the folk, and wars on them, and burns Beowulf's house.
