rulers of Egypt had entered the pyramid, and closed it again. Belzoni
also discovered another chamber in this pyramid.

The pyramid of Mycernius, the third in size of the Jizeh group, is about
330 feet square at the base, and 174 feet high. This pyramid has never
been opened.

There are some large pyramids at Sakkârah, one of which is next in
dimensions to the pyramid of Cheops, each side of the base being 656
feet, and the height 339 feet. At Dashour there are also some large
pyramids, one of which has a base of 700 feet on each side, and a
perpendicular height of 343 feet; and it has 154 steps or platforms.
Another pyramid, almost as large at the base as the preceding, is
remarkable. It rises to the height of 184 feet at an angle of 70°, when
the plane of the side is changed, to one of less inclination, which
completes the pyramid. At Thebes, there are some small pyramids of sun
dried bricks. Herodotus says, "About the middle of Lake Moeris, there
are two pyramids, each rising about 300 feet above the water. The part
that is under the water is just the same height." It is probable that
these pyramids were built on an island in the lake, and that Herodotus
was misinformed as to the depth of the water. There are numerous
pyramids in Nubia--eighty or more--but they are generally small.

The object of the Egyptians in building these pyramids, is not known.
Some writers maintain that they were as memorials, pillars, or altars
consecrated to the sun; others, that they served as a kind of gnomon for
astronomical observations; that they were built to gratify the vanity
and tyranny of kings, or for the celebration of religious mysteries;
according to Diderot, for the transmission and preservation of
historical information; and to others, for sepulchres for the
