have raised it from its bed, on account of its size, and the confined
space they would have to work in. I am inclined to think the top was
struck by lightning, and the position of the stone thus altered by it.
The three of us had just room to sit upon the place. The descent, as
might be expected, was much more dangerous, though not so difficult. The
guides tied a long sash under my arms, and so let me slide down from
course to course of these coverings of stones, which are of a yellowish
limestone, somewhat different from the material of which the steps are
composed, and totally distinct from the rock at the base, or the coating
of the passages."




EGYPTIAN OBELISKS.


Obelisks belong to the oldest and most simple monuments of Egyptian
architecture, and are high four-sided pillars, diminishing as they
ascend, and terminating in a small pyramid. Herodotus speaks of them,
and Pliny gives a particular account of them. The latter mentions king
Mesphres, or Mestres, of Thebes, as the first builder of obelisks, but
does not give the time; nor is this king noticed either by Herodotus or
Diodorus. It is probable that these monuments were first built before
the time of Moses, at least two centuries before the Trojan war. There
are still several obelisks in Egypt; there is one erect, and another
fallen at Alexandria, between the new city and the light-house; one at
Matarea, among the ruins of old Heliopolis; one in the territory of
Fayoum, near ancient Arsinoë; eight or ten among the ruins of Thebes;
the two finest at Luxor, at the entrance of the temple, &c. These
