Jacob Grimm and Wilhelm Grimm, Grimm's Goblins (1876) — Notes
“ In one of the tales before us, a mill-stone is treacherously thrown upon him while employed in digging at the bottom of a well. "Drive away the hens," said he; "they scratch the sand about till it flies into my eyes." "So in the Edda, the Giant Skrymmer only notices the dreadful blows of Thor's hammer as the falling of a leaf, or some other trifling matter. In the English story of Jack the Giant-killer, Jack under similar circumstances says that a rat had given him three or four slaps with his tail. ”
