The Book of Dreams and Ghosts

"A light was left burning in the hall, and when the third part of the night was past Grettir heard loud noises outside. Then something went up on top of the house, and rode above the hall, beating the roof with its heels till every beam cracked. This went on for a long time; then it came down off the house and went to the door. When this was opened Grettir saw the thrall thrust in his head; ghastly big he seemed, and wonderfully huge of feature. Glam came in slowly, and raised himself up when he was inside the doorway, till he loomed up against the roof. Then he turned his face down the hall, laid his arms on the cross- beam, and glared all over the place. Thorhall gave no sign during all this, for he thought it bad enough to hear what was going on outside. "Grettir lay still and never moved. Glam saw that there was a bundle lying on the floor, and moved further up the hall and grasped the cloak firmly. Grettir placed his feet against the plank, and yielded not the least. Glam tugged a second time, much harder than before, but still the cloak did not move. A third time he pulled with both his hands, so hard that he raised Grettir up from the floor, and now they wrenched the cloak asunder between them. Glam stood staring at the piece which he held in his hands, and wondering greatly who could have pulled so hard against him. At that moment Grettir sprang in under the monster's hands, and threw his arms around his waist, intending to make him fall backwards. Glam, however, bore down upon him so strongly that Grettir was forced to give way before him. He then tried to stay himself against the seat-boards, but these gave way with him, and everything that came in their path was broken.
