HISTORY OF THE PYRAMIDS. 37
globe, not compressed at the poles. It is not,
indeed, at all certain that the sacred cubit bore any
reference to the earth's dimensions ; but this seems
tolerably well made out—that the sacred cubit was
about twenty-five inches in length, and that the
circuit of the pyramid's base contained a hundred
inches for every day of the year. Relations such
as these are precisely what we might expect to
find in buildings having an astrological signifi-
cance. Similarly, it would correspond well with
the mysticism of astrology that the pyramid
should be so proportioned as to make the height
be the radius of a circle whose circumference would
equal the circuit of the pyramid's base. Again,
that long slant tunnel, leading downwards from
the pyramid's northern face, would at once find
a meaning in this astrological theory. The slant
tunnel pointed to the pole-star of Cheops's time
when due north below the true pole of the heavens.
This circumstance had no observational utility. It
could afford no indication of time, because a pole-
star moves very slowly, and the pole-star of
Cheops's day must have been in view through that,
tunnel for more than an hour at a time. But,
apart from the mystical significance which an
astrologer would attribute to such a relation, it
may be shown that this slant tunnel is precisely
