Hi Robin,

In a couple of threads a while back Graham Chase suggested that the correct alignment of Orion with Giza around 2500 bc was when Orion was rising - east of due south - rather than directly overhead. Here was one of them:

I posted a diagram about his idea that is not coming through on the old thread any more so here is a test of my image posting: Image post failed so here is the image:

A few years ago I also posted a diagram about the geometry of the shafts in the pyramid that was somewhat of an expansion of your drawings from the 90's:

I am pretty sure there is a typo in your earlier post about the exit heights of the KC shafts with over 100 inch difference where the 2 is supposed to be a 1. Petrie's diagram gives the north shaft at the bottom of 103 and the south shaft at the top of 103, and Petrie gives 25 inches for the height of course 103, so should be a bit less than 25 inches difference based on his diagram, but the top of 104 is supposed to be the 154 cubit level, so this remains a bit of a problem. In the text Petrie does say S comes out at 104 and N at 103, but that is basically what his diagram shows also.

I posted a new webpage about GP-Giza geometry recently and a lot of it is older material but some of it is newer and I think it adds up, but some is a bit hard to follow, even for me, and I wrote it...if interested, here is the webpage:

PS - Just noticed that the date of your Orion diagram in the SE sky is from 1996. I think Graham's idea was independent but yours earlier.
