Overlay of Osborn’s diagram of the Great Pyramid with the US version of ‘The Lost Symbol’
(Taken from http://www.freewebs.com/garyosborn/thepyramidcode.htm)

The base of the pyramid sits atop the text and the ‘tears’ follow the slope of the Pyramid quite nicely, enough to hint at it anyway.  Notice how the very apex of the pyramid is perfectly in-line with the top of the ‘33’ pyramid in the seal.  Notice also how the red ‘Equator’ line runs through both King and Queen’s Chamber to the very top left corner of the cover.  The red line bisecting the ‘33’ pyramid happens to point to the opposite corner.  The blue lines highlight the obvious 23.5 degree slant of the font.  There are more clues as well.  This is an obvious allusion to the overall message being handed down and possibly in Brown’s book. . . . Precession.

We can tell that the building is the US Capitol, but from what side?  There is the genius of Mr. Brown; the clues have been given but in two differing covers!
