Hidden Codes in Architecture

Today's the day! May 19 is the official opening day for the long-awaited movie, The da Vinci Code. Yes, we know. The movie (and the book it's based on) is fiction, not fact. But, author Dan Brown got one thing right when he wrote about the lost secrets of early Christians. Religious and spiritual symbols have played a powerful role in human history, and artists and architects often incorporate sacred codes and patterns into their designs. Sound far-fetched? Consider the eerie science known as "spiritual geometry."
