Hello Dave,
I have just noticed you website, well done. I have got as far as Dan Brown and the numbers.
And as long as the north-south hairs of the cross hairs split top of the 33 x 33 feet apex of the G.P. at 31 degrees 09 minutes east longitude, all is right with the world.
Thanks

PS
It is curious what can be contrived:
The Constitution of the United States consists of four sheets of about 28 3/4 by 23 5/8 inches, so each sheet has a diagonal of 37.2115 inches. And at 37.114 inches cubed twice is twice 6.84000e+13. And the field area of the Stars and Stripes, the national lag of the United States, is 6840 square units or 114 x 60 so a ratio of 10/19. So the ‘cross’ of the Constitution of the United States can be fashioned and formed out of the Death's reference number 19.
