Ok, so this is not strictly speaking a book by Lewis, but about his books. That the title bears striking resemblance to this website's name, pure coincidence!

Anyways, for those not familiar, it is a fairly new book by Michael Ward proposing a rather bold claim: All 7 narnia chronicles are based each on one of the 7 pre-Copernican "Planets", each planet having a personality and particular character associated with it. (These would be the same planetary personalities that descend on Ransom at the end of That Hideous Strength). The tie-in with Tolkien here is that Tolkien bears rather a large part of the responsibility for (inadvertently!) concealing this imaginative key to the chronicles, (seeing as his disdain of their mixed mythological imagery is well-known: others have seemed to follow in his steps and see a 'hodge-podge' of imagery in the chronicles, not least of which is the strange appearance of Father Christmas in a world that knows the name Aslan, not Christ). Ward contends that there is a hidden depth that ties all the seemingly random mixes of mythological symbols together. (Had the Chronicles been submitted to the full intellectual critique of Tolkien and other Inklings, this 'hidden' key might not have gone unnoticed by scholars for nigh well half a century).

Anyone read it? Heard of it? Thoughts?

Ah, but you were forgetting about the planet Mongo, the home of Ming the Merciless. Mongo's existence was known by the Illuminati even before Copernicus's time, having been visited by that planet's buzzing steam launches early in the 13th century.

That horrible Planet of the Apes was Earth: we know it was from ths last scene with the broken Statue of Liberty. So you may not count it twice.Sorry.
