Some Icelandic sagas mention sacred places. In both Landnámabók and Eyrbyggja saga, members of a family who particularly worshipped Thor are said to have passed after death into the mountain Helgafell (holy mountain), which was not to be defiled by bloodshed or excrement, or even to be looked at without washing first. Mountain worship is also mentioned in Landnámabók as an old Norwegian tradition to which Auðr the Deepminded's family reverted after she died; the scholar Hilda Ellis Davidson regarded it as associated particularly with the worship of Thor. In Víga-Glúms saga, the field Vitazgjafi (certain giver) is associated with Freyr and similarly not to be defiled. The scholar Stefan Brink has argued that one can speak of a mythical and sacral geography in pre-Christian Scandinavia.
