Reddit mentions of The Poetic Edda - Illustrated: Tolkien's Bookshelf #2 (Volume 2)

Ok well I tried harder and I found a few on amazon, I'll share links in case someone else has trouble and googles something like the name of this thread.

Egil's saga in monolingual old norse

A series of dual language sagas I have one of these, It's ok but I should mention that while it's dual-lingual, the languages are not parallel. the Norse version is in the back. Another thing is that some of them are actually modern Icelandic, though that shouldn't make a huge difference because the language used is still archaic, just with updated spellings (og vs ok, hestur vs hestr)

Here's a good one, The poetic Edda in parallel text old-Norse and English That's the version I have and I think it's a really nice, high quality volume, but one thing I should mention is it's a scan of an older edition. Personally I don't mind that, I actually think it's kind of cool, but if that idea bugs you maybe check out this version which I don't have so I can't speak for the quality of it but it seems to be newly printed instead of scanned.

The Prose Edda and Poetic Edda, from medieval Iceland, are the obvious suggestions, and the main sources on Norse mythology available to us. I highly recommend the Tolkien's Bookshelf edition of the Poetic Edda as it has side-by-side Old Icelandic and English, as well as the literal translations of the names of dwarves and giants etc. which reveal meaning where other translations conceal it.

I have to recommend the book by the author of that video: Sorcery and Religion In Ancient Scandinavia. However, it is unorthodox and offers a very different (but very satisfying and consistent with evidence from fairy tales, traditions and the like) interpretation of the mythology to that of most scholars. To be fully appreciated it does require some prior knowledge of Norse/Germanic mythology, which is why I suggest acquainting yourself with the uninterpreted myth beforehand.

There is also a lot you can find out from good Googling, from summaries of the whole mythology to various descriptions and interpretations of gods.

That said, you will be misinformed and find well-meaning yet misleading information. For example, Ragnarök is not an apocalyptic prophecy as many say, for the linear view of time is something introduced with Christianity: everything moved in cycles, which is an essential piece of information when interpreting the myth (i.e. the poem Völuspá is describing, under the guise of symbolism and divine personification, the movements of the year, and all high festivals and seasonal changes that take place). This is where Sorcery and Religion in Ancient Scandinavia comes in - challenging the scholarly theories and interpretations that are generally taken for granted.

Also don't forget that Germanic culture and religion is of the same origin as Greco-Roman: Indo-European culture. If you have a knowledge of the Greco-Roman, you will recognise similarities and parallels between the two mythologies. Very interesting to pick up on.
