Foucault's Pendulum - Umberto Eco

I've wanted to read this book for years.  Seriously.  It's always been like some legendary book that's really hard but really amazing - at least, that's the impression that I had gotten somewhere in my life.  I don't even know where.  So it was with excitement and nervousness that I picked up this book.  And - wow.  Here's a quote from early on in the book:

With six letters - Iahveh - he had seven hundred and twenty permutations at his disposal.  The repetitions didn't count, because Diotallevi had said that the two hes must be taken as two different letters.  Belbo could have chosen, say, the thirty-sixth or the hundred and twentieth.


Huh?

Okay, let's try this one.

"In Isaiah 9:2, for instance, there's the word "LMRBH," lemarbah - which, note the coincidence, means to multiply - but the mem in the middle is written as a final mem."


Um, yeah.  Of course it is.

Essentially, I think that this book is waaaaay over my head.  I made it to page 62 before being thoroughly confounded and confused and, well, feeling like a complete moron.  Maybe someone made a movie out of it that I can try watching?
