Another question for Scott re the lifting and lowering of the upper section of the Granite Leaf.
Given the fact that there is no gap between the Leaf's two sections; once the Leaf's upper section was lowered onto its lower section, how was the upper section raised again?
It would appear that once the Leaf's upper section was lowered on to its lower section there was no intention of raising it at sometime in the then future.
In which case there was no intention for the three portcullis blocks to be raised once they had been lowered onto the floor of the Antechamber.
Which ever way one looks at Scott's hypothesis, it simply does not work.
Scott and others have pointed out that the Antechamber's portcullis system gives very poor security to the King's Chamber.
I agree with this view.
However, this is only a valid point if one assumes that the King's Chamber was intended to house something of great value.
If it didn't - in other words, was devoid of any treasure - then we could be looking at something other than practical security.
Scott's suggestion is - if I understand him correctly - that the portcullis system was needed to stop air reaching the Grand Gallery.
A tad overkill, I would have thought.
All that would have been required was a close-fitting block of stone fitted with handles that could be pushed easily into and pulled out of the passage between the Grand Gallery and the Antechamber.
A bit of plaster around the edges of the block and, bingo, one very well sealed but easily reopened chamber, passage or whatever.
In this scenario, there was certainly no need for the Antechamber portcullis system.
So few answers - and not one of them mine.
