I just wanted to ask if anyone has come across any new information regarding the shafts?
Just to recap, I came across a serious discrepancy between Petrie's and Gantenbrink's figures for the shaft exits. I raised the question here a year or so ago. I wrote to Egyptological authorities and also joined the EFF where, with Alex Puchkov, a discussion took place on the question. There were many assertions, though no-one could direct me to any academic write up of Gantenbrink's claimed surveys, and the discussion petered out.. Yet the Egyptological consensus appears to favour him. If Petrie blundered at least amend the history books.

The question is not trivial. Whatever the purpose of the shafts, were they laid out to express an exclusively geometrical theme (Gantenbrink and Legon), or were they directed to mythically important stellar targets? If we had the true data (and more precise data for the Queen's Chamber shafts from the Djedi survey!) we might solve these questions.

But even without better shaft data what we have corresponds tolerably well to the altitudes within a degree or so of Orion's belt, Sirius, and Kochab (whose mythological significance remains unknown). Gods visible to all in Egypt, whatever their qualifications. So I wonder how it can be that architects supposedly creating a wholly geometric scheme happened to direct the southern shafts at altitudes very similar to those of their own important gods, isis and orion, without noticing the correspondence? Working from home I suppose.
Anyway it seems a bit premature to focus on Alnitak or Alnilam as target of KC south shaft, unless one wishes to accept the Orion correlation which makes Alnitak the target. Besides we assume the belt was the focus of the builder's attentions but no references or illustrations of the belt have come to light.
