Frigg and Freyja were two of the most revered goddesses in Norse mythology. They were especially worshipped by Vikings. Freyja is said to be the kindest among goddesses. In a poem in the Poetic Edda, a young man called Ottar always trusted in the goddesses; he built a rock shrine for the goddesses, and Freyja answered his prayers. She disguised Ottar as her golden boar, and went on a trip to help him find his ancestors.
