The Aswân Obelisk: With some remarks on the Ancient Engineering
Engelbach, Reginald
Egypt -- Antiquities; Obelisks
At the extreme left of the quarry-face, in the position indicated
on plate VI, there is an inscription of two lines in the hieratic
character. It is very faint indeed and I have not succeeded in
deciphering it. The fact that it is in black paint on very dark red
weathered granite has made it very difficult to photograph. It appears
to begin with a date, and to have a number in the middle, but there is
no name of a king.
(20) At the top of the upper quarry-face there is what seems to be the
bed from which a monument, very probably a small obelisk, of 7 metres
long has been extracted. The bottom of the trench can still be traced
where the work has been divided up into grooves of similar width to
those in the obelisk trench. Here the feet have become irregular, but
the double-foot is of great regularity and measures 59.8 centimetres.
Plate V, no. 2, shews the bed at the top of the rock face and no.
3 the same seen from above. It will be noticed that, in this case,
the undercutting has been done by pounding, but with less regularity
than in the obelisk trench, shewing that it was done by hand. The
obelisk seems to have been snapped off, or more likely it broke off of
itself. It is hardly justifiable to deduce how the large obelisks were
extracted from such a small example. In all probability the principle
was the same, but the details very different. This is discussed in
sections 21–23. {21}
At the west end of the ridge from which the monument has been removed,
there is a short inscription in red paint. A photograph of this is
given in plate V, no. 4. It seems to begin with the words [glyphs]
. . . . . “the work (of) . . . . . ”. The remainder is illegible
to me, though the signs are quite clear. They resemble some of the
quarry-signs I have seen at Maʿallah and elsewhere.

CHAPTER IV.
EXTRACTION OF OBELISK FROM QUARRY.
(21) Having examined, as far as possible, the methods by which the
obelisk was separated from the surrounding rock, we will consider
by what means the obelisk was detached from its bed and got into a
position in which it could be handled and transported.
It might be remarked that this particular obelisk has _not_ been
transported; there is no doubt, however, that the man responsible for
the work had quite definite ideas as to how he was going to perform
the feat. Although it is the largest obelisk known (_pace_ the phantom
108 cubit obelisk of Ḥatshepsôwet), the old engineers have actually
moved even heavier and more unmanageable blocks: the colossus of the
Ramesseum and the colossi of Amenophis III at Thebes. If we can solve
the ancient method of dealing with this particular obelisk, we can the
more easily understand how the others were dealt with.
There seem to be two methods by which the obelisk could be detached
from its bed; the snapping off of such an obelisk in the manner
mentioned in section 19 being out of the question.
