Geirrod
;)
was a frost giant, the father of two daughters, Gjalp and Greip, and was one of Thor's most formidable enemies. It happened that Loki, a constant companion of Thor, had taken the form of a hawk and was captured by Geirrod. The only way Loki could avoid death was to promise to bring Thor to Geirrod's hall without his magic belt and magic hammer which protected the god against frost giants.
Because Thor trusted Loki he went with him to Geirrod's hall. Fortunately, they rested on the way at the home of a friendly giantess named Grid, and she warned Thor about the plan while Loki was asleep. She also lent the god her own magic belt of strength, magic iron gloves and magic staff. Thus equipped, Thor arrived at their destination, with Loki hanging as usual on his belt. Geirrod was not at home, but the giant's servants received the visitors. It was not long, though, before Geirrod's two daughters tried to kill the slumbering Thor by lifting up his chair and dashing out his brains on the ceiling. But with the aid of Grid's staff, Thor succeeded in driving the chair downwards and crushed the frost giantess instead. However, Geirrod himself then appeared in the hall and using a pair of tongs he picked up a red-hot iron ball and threw it at Thor, who caught it in Grid's iron gloves. Angered beyond measure by this extremely discourteous action, Thor threw the still hot and smoking ball back down the hall, straight through an iron pillar and deep into Geirrod's stomach. After this, the thunder god laid about the frost giant's servants with the magic staff.
