 So to make gifts to Freyr, Eitri threw a pig's skin into a furnace as Brokkr worked on the bellows, and together they manufactured the boar Gullinbursti which had bristles in its mane that glowed in the dark.The story of Gullinbursti's creation is related in the "Skáldskaparmál" section of Snorri Sturluson's "Prose Edda".According to "Húsdrápa", Freyr rode Gullinbursti to Baldr's funeral, while in "Gylfaginning", Snorri states that Freyr rode to the funeral in a chariot pulled by the boar.
