CHAPTER I: THE ASTRONOMICAL THEORY
THE GREEKS of the time of Alexander
the Great were so impressed with the magnitude or splendour of
certain edifices, that they spoke of them as the seven wonders of
the world. Among these, the first place was given to the Pyramids
of Egypt, and pre-eminently to those of Ghizeh, which are situate a
few miles from Cairo, and in the neighbourhood of ancient Memphis.
The Pyramids of Ghizeh form a group of nine, consisting of three
large ones, known as the Pyramid of Cheops, or the Great Pyramid;
that of Cephren; and that of Mycerinus, which is inferior in size
to either of the others. The six other pyramids of the Ghizeh group
are much smaller, and arc supposed to be the tombs of female
relatives of the kings who constructed the larger ones. From the
term "Great" applied to the largest pyramid, it might be thought
that it far exceeds in size any of the others. As a fact, however,
the Pyramid of Cephren is not very much smaller than that of
Cheops, which was about 756 feet square at the base and 480 feet
high, as against 707 feet 9 inches the extreme length of the sides,
and 454 the height, of the Second Pyramid.Moreover, the construction of the two pyramids was, according
to Col. Vyse, carried on upon the same principles. This is true
more especially of the general design and external characters of
the buildings, which in their internal features, however, differ
considerably. The position of the chambers, and the inclination of
the passages of the Great Pyramid are exceptional, and, judging
from these peculiarities and from certain scientific facts supposed
to be embodied in it, several modern writers have affirmed that the
design for the Great Pyramid must have been derived from an
inspired source. The originator of this theory was John Taylor who
in 1859, published a book on the subject1and as in recent years it has attracted considerable
attention, chiefly through its adoption by the author of "Life and
Work at the Great Pyramid," Prof. C. Piazzi Smyth, the Astronomer
Royal of Scotland, and as the scientific facts on which it is based
are admittedly true, it is necessary to consider the
theory.In the first place, the Great Pyramid is said to embody in
its form and proportions certain facts as to the size and shape of
the earth. Thus, John Taylor says that the builders of the Great
Pyramid "imagined the earth to be a sphere, and as they knew that
the radius of a circle must bear a certain proportion to its
circumference, they built a four-sided pyramid of such a height in
proportion to its base that its perpendicular would be the radius
of a sphere equal to the perimeter of the base." This shape is
supposed to have reference to an important astronomical fact,
seeing that "the vertical height of the Great Pyramid multiplied by
10 to the 9th power (109) tells the mean distance of the sun from
the earth--that is, one thousand million times the pyramid's
height, or 91,840,000 miles."2Moreover, the Great Pyramid is thought to supply a standard
of linear measure, based on the length of the polar axis of the
earth. Assuming this length to be 500,500,000 of our inches, the
500 millionth of that axis (omitting fractions) will be one inch.
Of these inches, 25 or 25.025 of our inches would form a cubit or
longer standard, the ten millionth part of the semi-axis of the
globe in length, which is the measure of the sacred cubit of the
ancient Hebrews. This cubit of 25 earth inches is contained in each
side of the Great Pyramid as many times as there are days in the
year, and the inch itself "is contained separately and
independently in the entire perimeter of the Great Pyramid's base
just one hundred times for each day of the year."The inch is also said to be the "representative of a year in
the reckoning of the passage floor lines as charts of history, also
in the diagonals of the pyramid's base taken as a measure of the
precessional cycle." The Great Pyramid is found, moreover, to
furnish an important weight and capacity measure having relation to
the mean density or specific gravity of the earth. These earth
measures are said to be reproduced in the Coffer preserved in the
large or so called King's Chamber of the Great Pyramid, the
internal capacity of which vessel is just four times the measure of
an English quarter of wheat.The Great Pyramid was thus, according to the holders of the
inspiration theory, originally designed as a perfect and complete
metrological monument. This conclusion is thought to be supported
by the great astronomical knowledge possessed by the builders, who
were aware, not only of the shape and rotatory motion of the earth,
but also of its distance from the sun. They were able, further, to
do what was found so difficult up to a comparatively recent
date--to fix with precision the position of the four cardinal
points, as is shewn by the fact that the pyramid stands due North,
South, East, and West.The Great Pyramid is thus seen to be an important
astronomical monument, and it is no less remarkable in relation to
certain chronological facts. It is supposed to perpetuate the great
cycle founded on the precession of the equinoxes. This siderial
year is equal to 25,868 of our years, and the two diagonals of the
pyramid's base taken together are said to measure just the same
number of inches. It is thought, moreover, that by means of this
cycle the date of the erection of the pyramid can be ascertained.
Assuming that the long narrow downward passage leading from the
entrance was directed towards the pole star of the pyramid
builders, astronomers have shown that in the year 2,170 B.C. the
passage pointed to Alpha Draconis, the then pole star, at its lower
culmination, at the same time that the Pleiades, particularly
Alcyone, the centre of the group, were on the same meridian above.
This relative position of Alpha Draconis and Alcyone being an
extraordinary one, as it could not occur again for a whole siderial
year, it is thought to mark the date of the building of the Great
Pyramid.3It should be mentioned, however, that the date named is not
the only possible one. Mr. Richard A. Proctor the astronomer, after
stating that the Pole-star was in the required position about 3,350
B.C., as well as in 2,170 B.C., says "either of these would
correspond with the position of the descending passage in the Great
Pyramid; but Egyptologists tell us there can absolutely be no doubt
that the later epoch is far too late."He adds: If then we regard the slant passage as intended to
bear on the Pole-star at its sub-polar passage, we get the date of
the pyramid assigned as about 3,350 years B.C., with a probable
limit of error of not more than 200 years either way, and perhaps
of only fifty years."4The testimony of Mr. Proctor is important as he has recently
performed very valuable work in pointing out the true astronomical
meaning of the passages and galleries which distinguish the
internal structure of the Great Pyramid from that of other
pyramids. We may now accept the view that the former has been
erected with an astronomical purpose, although its measurements may
not have all the significance sometimes assigned to
them.Mr. Proctor, while admitting the existence of many of the
curious coincidences on which the theory of the inspired origin of
the Great Pyramid is based, gives an entirely different explanation
of them. He declares, indeed, "that they are mere coincidences, and
that they would still remain if the pyramid had no existence." The
fact that they exist, and are in themselves so singular, shows
simply how little value there is in the argument from mere
coincidence.5In support of this opinion, Mr. Proctor refers to "the of
relations, independent of the pyramid, which have turned up while
Pyramidalists have been endeavouring to connect the pyramid with
the solar system." "These coincidences," he says, "are altogether
more curious than any coincidence between the Pyramid and
astronomical numbers: the former are as close and remarkable as
they are real; the latter, which are only imaginary, have only been
established by the process which schoolboys call 'fudging,' and now
new measures have left the work to be done all over again."6The new measures here referred to show that the base of the
pyramid is several feet shorter than had been supposed, and this
will necessitate a change in the pyramid inch and in the length of
the cubit on which the astronomical relations of the Great Pyramid
were based.Mr. Proctor's own explanation of the peculiar features which
distinguish the internal construction of the Great Pyramid from
that of the other pyramids is very ingenious, and probably
conclusive: He says, we see "in all the Egyptian pyramids the
evidence of an astronomical plan; and in the Great Pyramid we find
evidence that such a plan was carried out with great skill, and
with an attention to points of detail which shows that, for some
reason or other, the edifice was required to be most carefully
built in a special astronomical position."Moreover, to obtain such accuracy, it was made to serve,
while being built, "the purpose of an astronomical observatory." To
this end, "the builders of the Great Pyramid used the passages
which they made within it to determine the proper position of each
part of it, up to the so-called King's Chamber, at least, and
probably higher."The slant descending passage was directed to the position of
the Pole-star when it was due north and at its lowest, for the
purpose of obtaining true orientation. As layer after layer of the
building was placed, this passage was carried towards the north
until it reached the northern face of the Pyramid. Here it was
compelled to terminate and another mode of observing the Pole-star
had to be used. This was effected by making a fresh passage "in
such a direction as to contain the rays from the Polestar after
reflection at a. horizontal surface, such as that of still
water."The reflecting surface required was obtained by plugging the
descending passage and pouring in water so as to partially fill the
angle thus formed, from which the rays would be reflected up the
ascending passage. Mr. Proctor remarks that thus far the pyramid
builders had "been working with manifest reference to the
meridional plane, just as an astronomer of our own time would; and
it looks very much, even from what we have already seen, as though
they had considered this plane for the same reason that the modern
astronomer considers it--viz., because this is the plane in which
all the heavenly bodies culminate, or attain the middle and highest
point of their passage from the eastern to the western horizon."
Mr.Proctor adds that at the point where the Grand Gallery commences
all doubt ceases. "The astronomical nature of the builder's purpose
becomes here as clear and certain as already the astronomical
nature of their methods had been. For from here upwards the small
ascending passage is changed to one of great height, so as to
command a long vertical space of the heavens, precisely as a modern
astronomer sets his transit circle to sweep the vertical
meridian."This Grand Gallery shows that it was intended for
astronomical observations by its double character, Its walls, taken
as wholes, are aslant, but every part of the them is absolutely
vertical, as would be required by an astronomer if his observations
were to be of value. To facilitate these observations, long slant
stone ramps or banks are placed at each side of the gallery the
whole of its length, with holes in them at equal distances for the
purpose of receiving [...]
