Thor returned home to Thrudvang, and the flint-stone sat fast in his head. Then came a sorceress, whose name was Groa, wife of Orvandel the Wise; she sang her magic songs over Thor until the flint-stone became loose. But when Thor perceived this, and was just expecting that the stone would disappear, he desired to reward Groa for her cure, and gladden her heart. He accordingly related to her how he had waded from the north over the rivers Elivagar and had borne Orvandel on his back in a basket from Jotunheim; and in evidence he told her that one toe of Orvandel had protruded from the basket and had frozen, wherefore he had broken it off and thrown it up into the sky and made of it the star which is called Orvandel’s toe. Finally he added that it would not be long before Orvandel would come home again. But Groa became so delighted with this news that she forgot all her magic songs and the flint-stone became no looser than it was, and it sticks fast in Thor’s head yet. Therefore no one must throw a flint-stone across the floor, for then the stone in Thor’s head is moved. Thus sings the Skald, Thjodolf of Hvin: We have ample evidence Of the terrible giant’s journey To Grjottungard, With berg-folks’ consuming fire The blood boiled in Meile’s brother,[65] The moon-land trembled. When earth’s son went To the steel-gloved contest. In bright flame stood All the realms of the sky For Uller’s step-father, And the earth rocked; To pieces flew Svolner’s widow When the span of goats Drew the sublime chariot And its divine master To the meeting with Hrungner.
