FORTY-SEVENTH<br />
FORTY-SEVENTH 271<br />
uge <strong>of</strong> forty days and nights, and the same<br />
number <strong>of</strong> days in which the waters remained<br />
upon the face <strong>of</strong> the earth ; the Lenten season<br />
<strong>of</strong> forty days' fast observed by Christians with<br />
reference to the fast <strong>of</strong> Jepus in the Wilderness,<br />
and by the Hebrews to the earlier desert fast<br />
for a similar period ; <strong>of</strong> the forty years spent in<br />
the Desert by Moses and Elijah and the Israelites,<br />
which succeeded the concealment <strong>of</strong><br />
Moses the same number <strong>of</strong> years in the land <strong>of</strong><br />
Midian . Moses was forty days and nights on<br />
the Mount. <strong>The</strong> days for embalming the dead<br />
were fort <strong>The</strong> forty years <strong>of</strong> the reign <strong>of</strong><br />
Saul, <strong>of</strong> David, and <strong>of</strong> Solomon ; the forty<br />
days <strong>of</strong> grace allotted to Nineveh for repentance<br />
; the forty days' fast before Christmas<br />
in the Greek Church ; as well as its being the<br />
number <strong>of</strong> days <strong>of</strong> mourning in Assyria,<br />
Phenicia, and Egypt, to commemorate the<br />
death and burial <strong>of</strong> their Sun God ; and as well<br />
the period in the festivals <strong>of</strong> the resurrection<br />
<strong>of</strong> Adonis and Osiris; the period <strong>of</strong> forty days<br />
thus being a bond by which the whole world<br />
ancient and modern, Pagan, Jewish, and<br />
Christian, is united in religious sympathy .<br />
Hence, it was determined as the period <strong>of</strong><br />
mourning by the Supreme Council <strong>of</strong> the<br />
A . A. Scottish Rite <strong>of</strong> the Northern Jurisdiction<br />
U . S.<br />
Forty-Seventh Problem . <strong>The</strong> forty-seventh<br />
problem <strong>of</strong> Euclid's first book, which has<br />
been adopted as a symbol in the Master's<br />
Degree, is thus enunciated : "In any rightangled<br />
triangle, the square which is described<br />
upon the side subtending the right<br />
angle is equal to the squares described upon<br />
the sides which contain the right angle ."<br />
Thus, in a triangle whose perpendicular is 3<br />
feet, the square <strong>of</strong> which is 9, and whose base<br />
is 4 feet, the square <strong>of</strong> which is 16, the hypothenuse,<br />
or subtending side, will be 5 feet,<br />
the square <strong>of</strong> which will be 25, which is the<br />
sum <strong>of</strong> 9 and 16 . This interesting problem, on<br />
account <strong>of</strong> its great utility in making calculations<br />
and drawing plans for buildings, is sometimes<br />
called the "Carpenter's <strong>The</strong>orem ."<br />
For the demonstration <strong>of</strong> this problem the<br />
world is indebted to Pythagoras, who, it is<br />
said, was so elated after making the discovery,<br />
that he made an <strong>of</strong>fering <strong>of</strong> a hecatomb, or a<br />
sacrifice <strong>of</strong> a hundred oxen, to the gods . <strong>The</strong><br />
devotion to learning which this religious act<br />
indicated in the mind <strong>of</strong> the ancient philosopher<br />
has induced Masons to adopt the problem<br />
as a memento, instructing them to be<br />
lovers <strong>of</strong> the arts and sciences .<br />
<strong>The</strong> triangle, whose base is 4 parts, whose<br />
perpendicular is 3, and whose hypothenuse is<br />
5, and which would exactly serve for a demonstration<br />
<strong>of</strong> this problem, was, according to<br />
Plutarch, a symbol frequently employed by<br />
the Egyptian priests, and hence it is called by<br />
M . Jomard, in his Exposition du Systeme<br />
Met ' des Anciens Egyptiens, the Egyptian<br />
trianglg e . It was, with the Egyp tians, the<br />
symbol <strong>of</strong> universal nature, the base representing<br />
Osiris, or the male principle ; the perpendicular<br />
Isis, or the female principle ; and<br />
the hypothenuse, Hors, their son, or the<br />
produce <strong>of</strong> the two principles . <strong>The</strong>y added<br />
that 3 was the first perfect odd number, that<br />
4 was the square <strong>of</strong> 2, the first even number,<br />
and that 5 was the result <strong>of</strong> 3 and 2 .<br />
But the Egy~t~ians made a still more important<br />
use <strong>of</strong> this triangle . It was the standard<br />
<strong>of</strong> all their measures <strong>of</strong> extent, and was<br />
applied by them to the building <strong>of</strong> the pyramids.<br />
<strong>The</strong> researches <strong>of</strong> M . Jomard, on the<br />
Egyptian system <strong>of</strong> measures, published in<br />
the magnificent work <strong>of</strong> the French savants on<br />
Egypt, has placed us completely in possession<br />
<strong>of</strong> the uses made by the Egyptians <strong>of</strong> this fortyseventh<br />
problem <strong>of</strong> Euclid, and <strong>of</strong> the triangle<br />
which formed the diagram by which it was<br />
demonstrated .<br />
If we inscribe within a circle a triangle,<br />
whose perpendicular shall be 300 parts, whose<br />
base shall be 400 parts, and whose hypothenuse<br />
shall be 500 parts, which, <strong>of</strong> course, bear<br />
the same proportion to each other as 3, 4, and<br />
5 ; then if we let a perpendicular fall from the<br />
angle <strong>of</strong> the perpendicular and base to the<br />
hypothenuse, and extend it through the hypothenuse<br />
to the circumference <strong>of</strong> the circle,<br />
this chord or line will be equal to 480 parts, and<br />
the two segments <strong>of</strong> the hypothenuse, on each<br />
side <strong>of</strong> it, will be found equal, respectively, to<br />
180 and 320. From the point where this cord<br />
intersects the hypothenuse let another line fall<br />
perpendicularly to the shortest side <strong>of</strong> the triangle,<br />
and this line will be equal to 144 parts,<br />
while the shorter segment, formed by its junction<br />
with the perpendicular side <strong>of</strong> the triangle,<br />
will be equal to 108 parts . Hence, we may derive<br />
the following measures from the diagram :<br />
500, 4801 400, 320, 180, 144, and 108, and all<br />
these without the slightest fraction . Supposing,<br />
then, the 500 to be cubits, we have<br />
the measure <strong>of</strong> the base <strong>of</strong> the great pyramid<br />
<strong>of</strong> Memphis . In the 400 cubits <strong>of</strong> the<br />
base <strong>of</strong> the triangle we have the exact<br />
length <strong>of</strong> the Egyptian stadium . <strong>The</strong> 320<br />
gives us the exact number <strong>of</strong> Egyptian<br />
cubits contained in the Hebrew and Babylonian<br />
stadium . <strong>The</strong> stadium <strong>of</strong> Ptolemy is<br />
represented by the 480 cubits, or length <strong>of</strong><br />
the line falling from the right angle to the<br />
circumference <strong>of</strong> the circle, through the hypothenuse.<br />
<strong>The</strong> number 180, which expresses<br />
the smaller segment <strong>of</strong> the hypothenuse being<br />
doubled, will give 360 cubits, which will be<br />
the stadium <strong>of</strong> Cleomedes . By doubling the<br />
144, the result will be 288 cubits, or the length<br />
<strong>of</strong> the stadium <strong>of</strong> Archimedes ; and by doubling<br />
. the 108, we produce 216 cubits, or the<br />
precise value <strong>of</strong> the lesser Egyptian stadium .<br />
In this manner, we obtain from this triangle<br />
all the measures <strong>of</strong> length that were in use<br />
among the Egyptians ; and since this triangle,<br />
whose sides are equal to 3, 4, and 5, was the<br />
very one that most naturally would be used in<br />
demonstrating the forty-seventh problem <strong>of</strong><br />
Euclid ; and since by these three sides the<br />
Egyptians symbolized Osiris, Isis, and Horus,<br />
or the two producers and the product, the<br />
very principle, expressed in symbolic language,<br />
which constitutes the terms <strong>of</strong> the problem<br />
as enunciated by Pythagoras, that the
