Seax-Wica is a tradition, or denomination, of the neopagan religion of Wicca which is largely inspired by the iconography of the historical Anglo-Saxon paganism, though, unlike Theodism, it is not a reconstruction of the early mediaeval religion itself.
The tradition was founded in 1973 by Raymond Buckland, an English-born High Priest of Gardnerian Wicca who moved to the United States in the 1970s. His book, The Tree, was written with the intent for it to be a definitive guide to Seax-Wica, and was published in 1974 by Samuel Weiser, though subsequently republished in 2005 as Buckland's Book of Saxon Witchcraft. There are also on-line Books of Shadows for the tradition on assorted websites.
The tradition primarily honours four principal deities: Woden, Thunor, Frig or Freya and Tiw. These are seen as representations of the Wiccan deities of the Horned God and the Mother Goddess. The tradition uses a minimal set of the usual ceremonial tools and a spear. Runes are significant and regularly discussed.
Seax-Wica does not employ any secrecy oath. The official books of Seax-Wica do not intend to omit or misrepresent itself, although they may be a bit sparse in terms of detail, leaving such things to individual practitioners or groups.
Buckland's Book of Saxon Witchcraft was written in mind that the reader would already be well versed in the various techniques of Witchcraft and Wiccan ritual, therefore intense study of other sources is imperative if one is looking to enter this tradition. However, Buckland has pointed out that his "Complete Book of Witchcraft" (commonly referred to as 'The Big Blue Book' and 'Big Blue') gives instructions on how to proceed when no tools are available. These instructions are enough to allow one to begin, self-initiate, and consecrate one's first tools.
