An average joe's description of the painting here.
The main focus of the painting is Mary (or Queen Mary as Catholics infer)... she is the centerpiece of the painting, the most highlighted and the whole painting is built around her. The very brightest area seems to illuminate right about Mary's left eye and a few cloud areas around her feet almost forming a halo around her...Mary is lifted on a cloud above everyone else. Almost like a Queen.
And your Da Vinci Code interpretation of this is what???? That is a secret symbol instead of an incredible piece of Church Art?
