Gerd, in Norse mythology, one of the Asynjur goddesses and wife of the fertility god Frey. Daughter of the mountain giants Gymir and Aurboda, Gerd was, according to the 'Prose (or Younger) Edda', the most beautiful of all women. Freyr married Gerd after he had suffered a long bout of lovesickness. Frey had spied Gerd one day while sitting on Odin's high throne, Hlidskjalf. He saw her at her father's homestead in Jotunheim, the land of giants, walking into a large building. Freyr fell deeply in love, and he began to pine desperately for Gerd. He would have died of lovesickness if his servant Skirnir had not volunteered to go to Jotunheim and ask for Gerd's hand on Frey's behalf. In exchange for this dangerous errand, however, Skirnir asked for Frey's magic sword. Frey agreed, and, armed with this sword, Skirnir was able to brave the dangers of Jotunheim.
Gymir's lands were well-protected: the walls were surrounded by flames, and fierce dogs and a watchman patrolled the gate. Skirnir ran past all obstacles, however, and Gerd, hearing the resulting commotion, came to the door. Skirnir told her why he had come and offered her gifts--11 apples made of pure gold and Odin's magic ring, Draupnir--if she would marry his master. When she refused, Skirnir angrily brandished Frey's magic sword and threatened to engrave magical runes into a spell that would send Gerd into a lonely wasteland and cause her to disappear like a thistle in the ice. Gerd became afraid and in a gesture of reconciliation offered Skirnir a bowl of mead. Then she agreed to meet and marry the god nine nights later.
Other than her relationship to Freyr, little is said about Gerd in the surviving literature. Gerd had a sister named Belli and may have been the personification of the Aurora Borealis, the Northern Lights.
