Basic Resources for Brythonic Polytheism (Recon Centred)
Available via Search Engine
Polytheist Community Boards- Brythonic Polytheism (link) https://polytheistcommunity.boards.net/board/24/brythonic-polytheism. This is a forum that has discussions on Brythonic god/esses, daily life as a Brython, and a handy list of god/esses that one can do more research on.
Dun Brython- a website created for the Brythonic community, with the same name on Wordpress. Easily found via a search engine of your choice with keywords ‘Dun Brython’. Dunbrython.org (link: http://www.dunbrython.org/ ) is very useful, and has a calendar, essays on the gods, and other aspects of the faith, such as giants, faerie, and ancestor veneration.
Caer Feddwyd- also easily found via search engine. Dun Brython was planned and submissions were called for on this forum. Also has many conversations still accessible regarding Brythonic polytheism, which encapsulates... a lot. Would spend another week scrolling through here.
Books (Primarily Celtic- Recon, not specificallly Brython-centric)
The Religion of the Ancient Celts, by J.A. MacCulloch- I have the first rate publishers version. Honestly, I need glasses to get through it due to the small font size but it’s indispensable. Chapter titles are fairly accurate to what is covered in that chapter, but pages aren’t numbered.
Pagan Britain (2013), by Ronald Hutton- it’s similar to a textbook, which is good. It’s purely listed for its research value. Fairly advanced writing, the ‘notes’ section alone is 59 pages. I advise reading with either google, a dictionary, or both easily available. I wish I was joking. His Blood and Mistletoe: The History of the Druids in Britain (2009) might be a bit more pagan-centric, but I’ve never read that, so I can’t very well advise others to. Note: Ronald Hutton is Big in research on paganism, both ancient and modern-day.
The Fairy-Faith in Celtic Countries by W.Y. Evens-Wentz. I like this mainly due to its ‘The Taking of Evidence’ section, which is a section of collected accounts of the Gentry, among other subjects. Ch. 10 is ‘The Testimony of Christianity’, which seems mainly to be a section devoted entirely to connecting polytheist beliefs to Purgatory. It’s from 1911, with a new foreword from 2004, so I mainly ignore ch. 10.
Dictionary of Celtic Myth and Legend, by Miranda J. Green. Useful for quick reference, although organization might be a bit odd. (Such as searching for Camulus under ‘Mars Camulus’).
Books: Honorable Mentions
I haven’t read, nor do I own either of these, so I can’t really recommend them.
Blood and Mistletoe: The History of Druids in Britain, by Ronald Hutton. This sounds like it might be a bit more pagan-specific, but I’m not sure. However, I would read almost anything by him.
Pagan Celtic Britain, by Anne Ross. A bit outdated, but it seems to be favoured by other Recons, so?? It is said to be very dry, as well.
Honorable Mention: Search Engine
Wikipedia. We all use it, and it’s useful to get a general idea as to where and how a god/dess is attested to.
