Wise-women, seeresses, rune-mistresses and healers were closely connected with Freya in the Viking world. She is the goddess of magic and love affairs (not marriages).
The female volva went about the ancient tribes giving predictions of the future through trance and were linked to cults of both Freya and Odin. They also did healing and occasional cursing. They did not marry, although they did take lovers. These women carried a staff with a bronze cap or mounting and wore capes, hoods and gloves of fur.
The sacred symbol of both Freya and her twin brother Frey is the boar. Boar images were used on ceremonial objects and war helmets. Some Teutonic tribes wore masks or helmets that covered the face and had a tusk protruding on each side.
A Swedish king had a helmet Hildgoltr (Battle Pig) and won another helmet Hildisvin (Battle Swine). Neck-rings and arm-rings also carried the boar symbol.
Freya was also known as the great "Dis". The "Disir" (goddesses) were nine women dressed in black and carrying swords. Nine ( a Moon number) was considered the most sacred and mysterious of numbers. At the beginning of Winter, particularly in Sweden, these (Spirits) and Freya were worshiped in a ceremony called the Disablot. The Disir brought good luck, but they were also merciless in exacting justice.
Seider is a form of magic, trance and divination that originated with Freya, and it was a feminine mystical craft. It was fairly independent of runic magic, being more involved in shape shifting, astral body travel through the nine worlds, sex magic and other techniques.
