Leonardo's Hidden Messages - Do they exist?

Whenever we choose books at a library, we may have some sort of idea what a book is about by its synopsis but sometimes we are presented with information we did not expect.

Recently I chose some books from my local library, all fictional crime novels, usually with some link to the past.

The first I read was a modern crime solving novel linked with King Arthur. What I hadn't realised was that it was linked to the Renaissance Artists too.

The second book I am reading is about Leonardo Da Vinci's painting, The Last Supper. It is set in the late 15th century and has a fictional murder implanted amongst the factual characters and places. It is really a vehicle for demonstrating research in to Leonardo, and Renaissance Painters in general, who liked to hide messages in their paintings! The book tries to help the reader understand how to break these hidden codes within the images.

One thing the book mentions is that the painting of the Last Supper has the tablecloth with a knot at the bottom and this is associated with Mary Magdelene. I decided to do some quick research on the net and found some interesting sights. I also saw an image of the painting with both ends of the tablecloth having a knot yet the book version only has a knot at one side. Which is the most accurate I wonder?

I have also looked at the following site: www.lastsupperreflection.com and can only say that it is miraculous what is being portrayed. You must see it to believe what is being presented on this site. I cannot demonstrate it in words alone!

The book I am reading about the Last Supper painting is by Javier Sierra and is entitled, The Secret Supper.

I cannot say whether any of the proposed information given is accurate or not, I am not that knowledgeable, but it is known that Da Vinci was an extraordinary person. I leave it up to you to decide for yourselves what should be believed.
