The Dísablót was the blót (sacrificial holiday) which was held in honour of the female spirits or deities called dísir (and the Valkyries), from pre-historic times until the Christianization of Scandinavia. Its purpose was to enhance the coming harvest. It is mentioned in Hervarar saga, Víga-Glúms saga, Egils saga and the Heimskringla. The celebration still lives on in the form of an annual fair called the Disting in Uppsala, Sweden.
The Dísablót appears to have been held during Winter Nights, or at the vernal equinox. 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. However, according to the Ynglinga saga part of the Heimskringla, the king of Sweden performed the rites, which was in accordance with his role as high priest of the Temple at Uppsala. The mention of the Dísablót concerns the death of king Eadgils (Aðils, Adils) who died from falling off his horse while riding around the shrine:
In Sweden, the Dísablót was of central political and social importance. The festivities were held at the end of February or early March at Gamla Uppsala. It was held in conjunction with the great fair Disting and the great popular assembly called the Thing of all Swedes.
