ubharedev,
I read the book.
It is pure fiction; very entertaining and well written.
It is full of bogus history that is scattered over many centuries.
Jesus did Not marry anyone.
He said His bride is The Church
The legend of the magic vessel did not appear until many centuries later.
Da Vinci would not have place Mary in with the apostles for he used the biblical account of who was at the Last Supper, There were NO women there.
The novel's accounts of the Catholic Church are riddled with errors to help fit the author's story.
There is an excellent book that tells of all the bogus history and errors avaiable. It is called The Da Vinci Hoax.
If truly interested get a copy of that,
It is available from Amazon at this site:
Amazon.com: The Da Vinci Hoax: Exposing the Errors in The Da Vinci Code: Carl E. Olson, Sandra Miesel: Books
Also here is a site you might be interested in.
It provides the scientific evidence for the Christmas Star over Bethlehem the birth place of Jesus.
THE CHRISTMAS STAR:
Peace and kindness,
Fred
