Are you sure about Glorfindel? I seem to remember a discussion way back, probably in the old Hobbit Hole, that this was just a reuse of a name, not the same character. Isn't it true that Tolkien talks about this matter in his letters?
Yes it was in the old Hole, I remember it well. Caused some trouble when I suggested that Tolkien screwed up and had to write himself out of a corner :) I'll see what I can find out in The Letters about this.
I was wrong...I wasn't around for a while. I forgot about the department appreciation luncheon. Then they gave us the rest of the afternoon off. I'm off to trim the verge before the neighbors start squawking!
The only real resource we have to answer this question is in The Peoples of Middle-earth (The History of Middle-earth Vol. 12): XIII Last Writings, Glorfindel. Christopher Tolkien dates the notes he gives here at 1972, the year before his father's death.I don't have that book...sorry :(
