Thor fights Hrungnir by Emil Doepler 1905

"Hrungner had, as is well known, a heart of stone, sharp and three-sided; just as the rune has since been risted that is called Hrungner's heart. Even his head was of stone. His shield was of stone, and was broad and thick, and he was holding this shield before him as he stood at Grjottungard waiting for Thor. His weapon was a flint-stone, which he swung over his shoulders, and altogether he presented a most formidable aspect. On one side of him stood the giant of clay, who was named Mokkerkalfe. He was so exceedingly terrified, that it is said that he wet himself when he saw Thor. Thor proceeded to the duel, and Thjalfe was with him. Thjalfe ran forward to where Hrungner was standing, and said to him: You stand illy guarded giant; you hold the shield before you, but Thor has seen you; he goes down into the earth and will attack you from below. Then Hrungner thrust the shield under his feet and stood on it, but the flint-stone he seized with both his hands. The next that he saw were flashes of lightning, and he heard loud crashings; and then he saw Thor in his Asa-might advancing with impetuous speed, swinging his hammer and hurling it from afar at Hrungner. Hrungner seized the flint-stone with both his hands and threw it against the hammer. They met in the air, and the flint-stone broke. One part fell to the earth, and from it have come the flint-mountains; the other part hit Thor's head with such force that he fell forward to the ground. But the hammer Mjolner hit Hrungner right in the head, and crushed his skull in small pieces. He himself fell forward over Thor, so that his foot lay upon Thor's neck."
