('Thought'), in Germanic mythology, was a young frost giant who outran Thor's human servant Thialfi in a race. The story of Thor's journey to the stronghold of Utgard in the land of the frost giants is full of magic. The race between Hugi and Thialfi was but one incident in this strange adventure, which shows Thor to be an ineffectual strong man in the face of cunning spells. Throughout the journey the trickster Loki, the god of fire, had cause to remind Thor of the superiority of brain over brawn. At one point Thor, Loki, Thialfi and his sister Roskva inadvertently slept in the thumb of an empty glove belonging to the enormous frost giant Skrymir, mistaking it for a vast ball. When he woke, Skrymir warned them that at Utgard there were giants even greater than he. Sure enough, when the travellers reached Utgard, they were unable to see the top of its battlements without pressing the crowns of their heads on the napes of their necks. Inside the great fortress Thor and his companions failed in a number of tests, the thunder god himself being wrestled down on one knee by an 'old, old woman'. He also failed to empty a drinking horn, only to learn afterwards how its other end was in the sea. At the end of their adventure, however, the travellers saw that Skrymir and Utgard were no more than magic creations sent our by the frightened frost giants to mystify mighty Thor.
