Myths Transformed

[Mithadan]

Since this barrow has been so slow lately, I thought I'd throw this into the mix. In the ancient history of the canon project, there was an extended discussion of the Myths Transformed section of Morgoth's Ring and the part that those writings should play in the canon. Flat earth v. round earth, the origin of Orcs and a central issue strongly related to all the others: are the Silmarillion tales Elvish or Numenorean in genesis?

I was reading a piece of the "Canon", i.e. works by JRRT published during his lifetime, which is generally overlooked: Tales of Tom Bombadil. The poems themselves are "Hobbitish" in origin or translations of works by Bilbo. However, the Introduction is, of course, by Tolkien in his full "I translated the Red Book" mode (fun reading in itself). In the intro, there is a reference to the tale of Turin and Mim, which was part of ME's then obscure history. JRRT describes the Turin/Mim tale as "Numenorean", not a translation from Elvish. This could be considered a clear statement of JRRT's intent in the Canon (note the upper case "C", meaning published during his lifetime)about a central Myths Transformed concept which may place the related revisions in play for canon (lower case "c" for our canon) treatment. Consider this an attempt to stir up the beehive. Thoughts?
