Main article: Anglo-Saxon mythology
The indigenous pre-Christian belief system of the Anglo-Saxons was a form of Germanic paganism and therefore closely related to Norse mythology, as well as other Germanic pre-Christian cultures.
Christianity (both Celtic and Roman) replaced the indigenous religion of the Saxons in England around the 8th and 9th centuries AD. The Synod of Whitby settled the choice for Roman Christianity. As the new clerics became the chroniclers, the old religion was systematically lost before it was recorded and today our knowledge of it is largely based on surviving texts, etymological links and archaeological finds.
One of the few recorded references is that a Kentish King would only meet the missionary St. Augustine in the open air, where he would be under the protection of the sky god, Woden. Written Christian prohibitions on acts of paganism are one of our main sources of information on pre-Christian beliefs.
Remnants of the Anglo-Saxon gods remain in the English language names for days of the week:
Tiw, the Anglo-Saxon equivalent of Tyr, the god of war: Tuesday
Woden, the Anglo-Saxon equivalent of Odin, the one-eyed wise god of storms and the dead: Wednesday
Žunor, the Anglo-Saxon equivalent of Thor, the thunder god: Thursday
Frige, the Anglo-Saxon equivalent of Freya, the love-goddess: Friday
Wikipedia is where to find it.
Damn you Anglo-Saxon buggers. But this really enforces that the Vikings and the Anglo-Saxons were the same peopel and possibly the Celts as well. Just from different Areas.
