Pyramid of Khufu (Cheops)

The next section consists of a horizontal passageway from the topstone in the Grand Gallery to the so-called King´s chamber, but in the middle of the passageway, there is an Antechamber with a peculiar locking system which should prevent intruders from entering the King´s chamber. It is obvious that the locking system did not keep out the intruders - whoever they were - and this passageway has been unbearable vandalized.

Even the doorway in the southern wall of the Grand Gallery is vandalized. Hereunder are photos of the doorway taken by Edgar.

My comments:
The northern doorway near the great step in the Grand Gallery:
Height: 43,7" = 2,12 cubits RM, which is rounded up to 2,1 cubits RM in the drawings.
Width: 41,5" = 2,01 cubits RM, which is rounded up to 2,0 cubits RM in the drawings.

The southern doorway near the King´s chamber:
Height: 43,6" to 43,8" = 2,11 cubits RM to 2,12 cubits RM, which is rounded up to 2,1 cubits RM in the drawings.
Width: 41,4" = 2,01 cubits RM, which is rounded up to 2,0 cubits RM in the drawings.

It seems the northern doorway is located exactly in the middle of the southern wall of the Grand Gallery on the great step.
According to section 5.5.10 the width between the walls in the Grand Gallery is 3,98 cubits RM, so the walls east and west for the doorway has a width of:
( 3,98 cubits RM - 2,01 cubits RM ) / 2 = 0,99 cubits, which is rounded up to 1,0 cubits in the drawings.

According to section 5.5.10 the coordinates of the southern corners in the Grand Gallery is:
East - south corner: 2041;2170
West - south corner: 2081;2170

According to section 5.5.9 the up-down coordinate at the above mentioned corners is: 1979

The black marked area:
This is the northern wall, the black area is the doorway to the Grand Gallery. On top of the doorway there are 3 limestones marked "L". On the left (west) side there is a granite wainscot a bit taller than the granite wainscot on the right side (east).

The red marked area:
The wainscot is a bit lower than the wainscot on the western wall. The wainscot consists of 4 broad grooves and 4 pilasters. The first groove is occupied by a partly destroyed granite twinstone partly standing on a limestone.

The yellow marked area:
The southern wall consists of the doorway to the "Kings" chamber (black area), the two wainscots and 4 grooves of which the lower part is partly destroyed.

The green marked area:
The western wall has the tallest wainscot also consisting of 4 broad grooves and 4 pilasters. The granite twinstone is drawn from the other side. The twinstone has a boss on the upper part. The 3 most southern broad grooves has semicircular hollows. The irregular hole (black area) is made by an intruder.

The purple marked area:
This is the ceiling of the Antechamber consisting of 3 granite stones.

The blue marked area:
This is the top view of the floor at the floor level.

My comments:
116,30" = 5,6 cubits RM or 8,0 remens RM, (the mean length).
65,00" = 3,2 cubits RM or 4,5 remens RM, (the breath).
149,35" = 7,2 cubits RM or 10,2 remens RM (the height).

152,85" ± 0,2" = 7,4 cubits RM ± 0,010 cubits or 10,5 remens RM ± 0,014 remens, (ceiling over the virtual end of the gallery floor).
1841,8" ± 0,6" = 89,3 cubits RM ± 0,029 cubits or 126,3 remens RM ± 0,041 remens, ( over the payment).

"On the wainscot block at the S. end of this wall, which is all in one with the S. end of the chamber, are two conjoined deep scores or scrapes nearly vertical, much like the beginning of a regular groove; their distance from the S. wall is 3,6 to 7,2 at 90, and 2,6 to 6,4. at 52 from floor, where they end; they are 0,48 deep at maximum. The S. wall has all up the E. side of it, over the wainscot, a projection, just equal in width to the wainscot, and varying in thickness from 0,31 at top to 1,7 half-way down, and thence fading off down to the top of the wainscot. On the W. side of the S. wall the granite has been daubed over for 2 to 6 inches in breadth, with a thin coat of cement ; this, at 1 inch from the

side is 0,35 thick ; also at 13 from the W. side is a slight sinking of the granite, from 0,34 to 0,60 in depth, all quite ill-defined."

To give a better understanding of Petrie´s text, I have repeated it here, but replaced the figures in British inches by the figures in cubits RM:

"On the wainscot block at the S. end of this wall, which is all in one with the S. end of the chamber, are two conjoined deep scores or scrapes nearly vertical, much like the beginning of a regular groove; their distance from the S. wall is 0,18 cubits RM to 0,35 cubits RM at 4,37 cubits RM, and 0,13 cubits RM to 0,31 cubits RM. at 2,52 cubits RM from floor, where they end; they are 0,023 cubits RM deep at maximum. The S. wall has all up the E. side of it, over the wainscot, a projection, just equal in width to the wainscot, and varying in thickness from 0,015 cubits RM at top to 0,082 cubits RM half-way down, and thence fading off down to the top of the wainscot. On the W. side of the S. wall the granite has been daubed over for 0,10 cubits RM to 0,29 cubits RM in breadth, with a thin coat of cement ; this, at 0,048 cubits RM from the side is 0,017 cubits RM thick ; also at 0,63 cubits RM from the W. side is a slight sinking of the granite, from 0,016 cubits RM to 0,029 cubits RM , all quite ill-defined."

Section 5.9.12

Western wall:

"The W. wall has the top of the granite wainscot uneven, rising toward the front, and there sinking suddenly 0,35 at 1,4 from the front edge. The southern of the three semicircular hollows on the top of this wainscot (see PI. xii.)* has the granite defective at the back of it, and is backed with rough limestone there. The southernmost stone over the wainscot is dressed very flat and true, but rough, + or — 0,03. The next block has a raised edge to it on the S. side (figured by Prof. Smyth), and along the base of it, which consists of granite left rough, not dressed away in finishing ; about 4 inches wide, and 0,4 projection along the lower edge of the block ; and 2 wide and 1,2 maximum projection at the side. The other edges of this block were marked out by saw-cuts in the granite, about 0,2 deep, to guide the workmen in dressing the face."

My comments:
0,35" = 0,017 cubits RM = 0,024 remens RM
1,4" = 0,068 cubits RM = 0,096 remens RM
0,03" = 0,001 cubits RM = 0,002 remens RM

1,2" = 0,058 cubits RM = 0,082 remens RM
0,2" = 0,010 cubits RM = 0,014 remens RM

Again; I have replaced inches by cubits RM in Petrie´s text:

"The W. wall has the top of the granite wainscot uneven, rising toward the front, and there sinking suddenly 0,017 cubits RM at 0,068 cubits RM from the front edge.

The other edges of this block were marked out by saw-cuts in the granite, about 0,010 cubits RM deep, to guide the workmen in dressing the face."

Section 5.9.13

Southern wall:

"The south wall has four vertical grooves all up it, which have been hitherto supposed to have extended down to the top of the passage to the King's Chamber. This was not the case, however ; for, though much broken away, it is still clear that they became shallower as they neared the bottom, and probably ended leaving an unbroken flat surface over the doorway. Their depths (as well as the forms of their sides) show this, as follows :"

"50. The granite leaf which stretches across the chamber, resting in grooves cut in the granite wainscots, must be somewhat less in width than the breadth between the grooves, i.e., 48,46 to 48,76. Its other dimensions were carefully ascertained, as much theoretic importance had been attached to them ; though to anyone looking at the object itself, the roughness and irregularity of it would put any accuracy of workmanship out of the question. The thickness of the two stones that form it was gauged by means of plumb-lines at 33 points ; it varies from 15,16 to 16,20, but the details are scarcely worth printing. This leaf is not simply a flat slab of granite, but on both its upper and lower parts it has a projection on its N. side, about 1 inch thick, where it is included in the side grooves. The edge of this projection down the W. side has been marked out by a saw cut ; and the whole of the granite on the inner side of this cut has been dressed away all over the face of the leaf, leaving only one patch or boss of the original surface of the block.

This boss, of which so much has been made by theorists, is merely a very rough projection, like innumerable others that may be seen ; left originally for the purpose of lifting the blocks. When a building was finished these bosses were knocked away (I picked up a loose one among waste heaps at Gizeh) and the part was dressed down and polished like the rest of the stone. It is only in unimportant parts that they are left entire. This boss on the leaf is very ill-defined, being anything between 4,7 and 5,2 wide, and between 3,3 and 3,5 high on its outer face ; at its junction with the block it is still less defined, and might be reckoned anything between 7,2 and 8,2 wide, and 5,6 to 6,6 high. It projects 0,94 to 1,10 from the block, according to the irregularities of the rough hammer-dressing. Anything more absurdly unsuited for a standard of measure it would be difficult to conceive. I write these remarks with a sharp plaster cast of it before me that I took in 1881. Traces of another boss remain on the W. wall of the Antechamber, above the wainscot ; here there has been a boss 12 inches wide and 9 high, which has been knocked away, and the surface rough dressed, though the rest of the face of the stone is ground down elsewhere. The block has been turned in building, so that the flat under-edge of the boss is toward the N. Remains of another boss may be seen on a block in the passage to the King's Chamber ; remains of 15 or 16 others in the King's Chamber 5 others complete in the spaces above that ; and many on the casing of the Third Pyramid and elsewhere (see PL xii). The E. to W. breadth of the leaf between its side ledges in the grooves, varies from 40,6 to 41,2 at different heights up the middles of the ledges ; but furthermore, the edges are not square, and we may say that 40 to 42 will about represent its irregularity. Yet this was another so-called " standard of measure " of the theorists. The top of the upper block of the leaf is a mere natural surface of the granite boulder out of which it was cut, utterly rough and irregular ; and not materially broken away as it dips down deeply into the grooves, and is there plastered over. It varies from 51,24 to 59,0, and perhaps more, below the ceiling."
