[Mithadan]

Without joining issue on the wings/no wings debate, the article is well written Fingolfin. Indeed, were it not for the "its wings were spread from wall to wall" quote, I would agree with your reasoning. Here, the word is not used as an adjective and the sentence appears free from any earlier simile or metaphor-like usage. To rebut the "pro-wings" position, you must somehow address the above quote, perhaps by linking it to an earlier simile (as others have argued here). In other words, you must somehow establish that the quote really means "Its shadow was spread from wall to wall". Thoughts?
