"'Countless scholars of that era chronicled Mary Magdalene's days in France, including the birth of Sarah and the subsequent family tree.'
Sophie was startled. 'There exists a family tree of Jesus Christ?'
'Indeed. And it is purportedly one of the cornerstones of the Sangreal documents. A complete genealogy of the early descendants of Christ.'
'But what good is a documented genealogy of Christ's bloodline?' Sophie asked. 'It's not proof. Historians could not possibly confirm its authencity.'
Teabing chuckled. 'No more so than they can confirm the authenticity of the Bible.'
'Meaning?'
'Meaning that history is always written by the winners. When two cultures clash, the loser is obliterated, and the winner writes the history books - books which glorify their own cause and disparage the conquered foe. As Napoleon once said, "What is history, but a fable agreed upon?" 'He smiled. 'By its very nature, history is always a one-sided account.'"

Hmmm... very interesting...
