Gna
Gna was Frigga’s swift messenger. Mounted upon her fleet steed Hofvarpnir (hoof-thrower), she would travel with marvellous rapidity through fire and air, over land and sea, and was therefore considered the personification of the refreshing breeze. Darting thus to and fro, Gna saw all that was happening upon earth, and told her mistress all she knew. On one occasion, as she was passing over Hunaland, she saw King Rerir, a lineal descendant of Odin, sitting mournfully by the shore, bewailing his childlessness. The queen of heaven, who was also goddess of childbirth, upon hearing this took an apple (the emblem of fruitfulness) from her private store, gave it to Gna, and bade her carry it to the king. With the rapidity of the element she personified, Gna darted away, and as she passed over Rerir’s head, she dropped her apple into his lap with a radiant smile.
“‘What flies up there, so quickly driving past?’
Her answer from the clouds, as rushing by:
‘I fly not, nor do drive, but hurry fast,
Hoof-flinger swift through cloud and mist and sky.’”
Asgard and the Gods (Wagner-Macdowall).
The king pondered for a moment upon the meaning of this sudden apparition and gift, and then hurried home, his heart beating high with hope, and gave the apple to his wife to eat. In due season, to his intense joy, she bore him a son, Volsung, the great Northern hero, who became so famous that he gave his name to all his race.
