Norse Mythology: Listed by Snorri as one of the twelve divine goddesses, she appears mainly to function as Frigg's maid, taking care of the goddess's shoes. She also, sometimes, functions as Frigg's messenger. Some believe she is Frigg's sister. Snorri stated she was a virgin with long golden hair who wore a gold band around her head. It has been suggested that this band represents the binding around a sheaf of grain, making her a fertility goddess.
When Hermod rode to Hell to ask Hel if Balder could return to Asgard, Nanna gave him a gold ring to give to Fulla, among other gifts. Fulla is called a maid of Frigg in The Lay of Gimnir in the Poetic Edda, and is sent on an errand by Frigg. We also have mention of Fulla in Gisla saga Surssonar:
My Fulla, fair faced, the goddess of stones
Who gladdens me much, shall hear of her friend
Standing straight, unafraid in the rain of the spears...
He died in combat in the crags soon after uttering these words. He had been fighting off his assailants with stones and sword, and was burried under stones, which was customary.
