 In one version of "Hervarar saga", there is a description of how the sacrifice was performed.Alfhildr, the daughter of king Alfr of Alfheim, was kidnapped by Starkad Aludreng while she was reddening a horgr with blood.This suggests that the rite was performed by women, especially in light of what is generally believed to be their nearly exclusive role as priestesses of the pagan Germanic religion.
