The 500th post!
What amazes me - actually it doesn't - is how much discussion can occur on what an author may (or may not) have thought perfectly clear. Tolkien may not have given this scene a second thought, and PJ may have thought that the 'Gandalf prone' scene was exactly what was called for in his interpretation of the texts. And yet we've reached 500 (and more, if we count other posts in other threads).
These are what schisms are made of...
