The Ascending Passage

The junction point has some extraordinary distinctive features; it has so many complications that looks like an inextricable mystery.

First of all, if someone would stop under the passage forking,  watching up, he could see just an impressive granite monolith threateningly appearing from the ceiling, as it could fall down on the imprudent watcher (see block-plug photo).






But this granite block cannot fall down because the ceiling stone blocks of the descending passage, laterally narrowed as a bottleneck, don’t  allow it. Also the granite block is wedge-shaped: it has no space enough to go through.

If this narrowing point weren’t there, the granite block would fall down with the next two, probably dropped  from an higher position, sliding down inside the ascending passage, because the size allow it.

It is possible to see that there are just few millimetres from the corridor measures and the granite plug faces.

It is clear that the three blocks are a pyramid lock, to prevent the upstairs room entrance.

Only the first block is tapered to get stuck in the ceiling of the beneath passage; the remaining two have the normal prismatic shape and the size just a little bit smaller than the ascending passage, where they all slid down.

The third block, the upper one, is uncompleted in its second part, like someone had tried to demolish it and , probably, this is what happened.

Just the second block is completed and it shows a regular shape; this is the reason I assumed its dimension like representative of the remaining missing blocks, 25 at least,  which could have been used to lock the entrance ( and I’m not alone to suppose it ).

Let’s speak about this block. It is 119 cm high ( = 2c+2p ), 104,5 cm wide ( = 2c ) and 170 cm long   ( = 3c+1/4c ); the weight about 5600 Kg, very heavy really: a big problem for the violators.

If some imprudent people, working from the passage beneath, would have the first block released, he would have had the shocking surprise to have the remaining blocks dropped down and if the blocks had been 25….., a very long time had been occurred to remove them.

The Sheik Al-Mamun, who first desecrated the upper part of the pyramid in the 820 a.d., thought something like that for sure.

He began the job using steel tools, working in the sunlight, because he didn’t need to hide himself, like a tomb profaner.

Al-Mamun probably entered the pyramid from the main entrance, he went down to the subterranean chambre treasure he looked for, and he wondered the big granite block in the passage ceiling: it  looked so nasty….

Fearing the worst, the Sheik  undertook digging the pyramid limestone wall starting from a level just a little bit below the two passages junction.

The excavation went up and around the blocks to emerge by the west side of the last granite block.

Easy to distinguish the granite from the limestone…..

I imagine, at that point, Al-Mamun started to demolish the granite block obstructing the passage, discovering it was the last one and, beyond that, the upper passage was accessible, even if with difficulty.

My point of view, about Al-Mamun digging, is quite different from the official version, reporting he dug an horizontal narrow passage inside the pyramid, leading him just by the granite blocks: the way the tourists go in today.

I think this is not right, the dig, if going up from the bottom side of the granite blocks, needs to start from the lower passage, which is not connected to the horizontal passage: that means something is wrong.

I suppose that dig is due to the Sheik, but I have a different opinion about the purpose of that. I’ll tell you something about later on: now my goal is not this.

Going up the ascending passage, we can see three stone belts, wrapping laterally the passage like a sheath, named “Girdle Stones". Each  Girdle Stones is  made by two stones, one in the top and one in the bottom of the passage according to a very complicate plan.

Each Girdle Stones is 10c far from the next one ( about 5 m. ). As the first one is 35c from the junction point and because the passage is 75c long, the result is the last Girdle Stones is 20c ( 10m. ) from the upper end.

There are more complications: at every GS position: it is possible to find some special small stone, prismatic shaping, inserted alternately in the wall: the reason of those not easy to explain.

This ascending passage ends upstairs, at a complicate crossing named “ Quadrivium “.
