The Cult
No sanctuary of Freyja is named in any source, and the theophoric place-names that crowd her brother's cult across Norway and Sweden mostly pass her by — Norway's Frøya island and a handful of debated sites are all she has on the map. The one firm cultic datum is textual: in Ynglinga saga Freyja is blótgyðja, a sacrificial priestess among the Vanir, who taught the Æsir seiðr and kept rites of her own — Snorri's euhemerized memory of a goddess whose office was ritual practice rather than a temple's estate. That is a slim dossier, and it fits her. Where Þórr has his Uppsala and Óðinn his hanged, Freyja has a practice — the staff, the trance, the chant — and the Viking-Age graves give it bodies: the high-status völva burials with their iron staffs, from which modern scholarship has reconstructed the working priesthood of her magic. Modern Ásatrú's seiðr revival claims that lineage directly, and calls her its first teacher.
