At first Hrungnir could not see Thor. All he observed were flashes of lightning and claps of thunder. What he was seeing of course was Thor in his divine state and elemental. Thor running towards the Jotun threw his mighty hammer first. Seeing this Hrungnir grasped his hone in both hands and with all his might flung it at the hammer. The two mighty battle weapons collided in mid - air, with Mjollnir smashing straight through the hone, and breaking it into tiny pieces. A few of these pieces were flung through the air with such force that they hit Thor and became lodged in his head. The hammer, as it was designed, continued straight and true and hit Hrungnir square in the head. Hrungnir' s head, which was made of stone, shattered to pieces and the Jotun fell dead on top of the victorious God.
Seeing that Thor was now defenseless under Hrungnir' s lifeless body Thjalfi attacked the clay creature Mist Calf, and using his great speed killed it with little problem. Thjalfi then ran back to Thor and tried to lift off the Giant' s leg, but though his efforts were great he was not strong enough to remove the leg that pinned Thor down. When the Aesir heard that their champion Thor was down they rushed to the battlefield in Grjotunagardar to aid their comrade. One by one they tried to remove the Giant' s leg but none were strong enough to lift it off of Thor.
At this point the three year old son of Thor and Jarnsaxa, Magni happened by. Magni casually walked over to where his father lay and with little effort flung the offending leg off of his father. Magni then boasted to Thor, and anyone else in earshot, " What a pity I did not come sooner father ! I believe I would have struck the Giant dead with my bare fist if I had met him. Thor was very appreciative of his son and wanted to give Magni the Jotun' s horse Gold Mane, but a jealous Odin declared : " It is wrong to give such a fine horse like that to the son of a Giantess ( Jarnsaxa ) instead of his own father ! "
When Thor went home to Thrudvangar he still had the piece of the hone stuck in his head. One day a sibyl named Groa, who was the wife of Aurvandil the Brave, came to visit Thor. She chanted spells over the Thunder God until the fragment of the hone began to work loose. Thor was so happy that her spell was working that he wanted to reward Groa for helping him. Thor told the sibyl the news that he had waded South over Elivagar carrying her husband Aurvandil on his back in a basket out of Jotunheim. To prove that Aurvandil was safe Thor told her that one of his toes had stuck out of the basket and froze. So Thor to honor Aurvandil broke it off and threw it into the sky and made of it the star named Aurvandil' s Toe. Groa was so happy that her husband would soon be coming home that she forgot her spells, and the hone did not work its way any further out of his head.
I love this story on so many levels . Thor is shown to be a great and honorable God who kept his word and came to the battlefield to fight the duel with Hrungnir rather than simply kill an unarmed Jotun in Odin's Hall. When he sees that he has been deceived by the Jotuns, who made the Clay monster, he is helped by his friend and companion Thjalfi, who tricks the Jotun into lowering his shield. He also kills that same clay monster while Thor was defenseless. This shows me a great level of love and respect that the farmer's son has for the Prince of Asgard. I am also touched by Thor's gifting of the horse to his son Magni, and at the same time a little disappointed that Odin would show himself to be selfish. Finally I am enlightened by the fact that every Aesir came out of Asgard to Jotunheim to try and help the great defender of both Asgard and Midgard. It shows just how important the Mighty Thor is to Gods and men alike !
Next : Thor meets an evil Jotun without his mighty hammer !
Go with Odin's wisdom, Freyja' s love, and Thor's protection !
