There are 366 sunrises from one Winter Solstice to the next; let us
suppose that the ancient stone builders decided that there were 366 days
in the year.
Professor Thom had very skillfully demonstrated that the Megalithic Yard
(2.72ft or 2’ 8.64”) was in evidence in the ancient structures
throughout much of western Europe, yet was unable to identify how it had
been arrived at.
Time is the key. The ancient builders divided their circle into 366 parts.
How long does it take for the sun or a bright star to traverse one degree?
It is relatively simple to do – place two posts one degree apart,
and observe. Then create a pendulum and adjust its length until it gives
exactly 366 beats for the full appearance of a star between two posts
placed a megalithic degree apart.
As a 366th part of one revolution of the Earth, a megalithic degree is
equal to just over 236 seconds, or 3.93 minutes of time. The length of
pendulum that produces exactly 366 pulses is 16.32 inches in length.
Thom had doubled up the basic unit he had found to make his megalithic
yard appear close to a modern yard. He had observed the smaller unit but
chose to call it “half a Megalithic Yard”. So, doubling the
length of the pendulum, it comes out to exactly 32.64”. A precise
Megalithic Yard!
This is the answer to one of the greatest puzzles of prehistory. Once
understood, anyone could use this principle to find the “sacred length”
without reference to anyone else. It would work anytime, anywhere, and
it would be totally accurate. This explains the consistency of accuracy
found throughout Europe, over such a large area.
The Megalithic Yard is a truly staggering concept of measurement. It is
based on three absolutely fundamental values:
1). The orbit of the Earth around the sun
2). The rotation of the Earth on its own axis
3). The mass of the Earth.
The Earth’s orbit gave the 366 split of the horizon, the rotation
of the Earth gave the time span, and the mass of the planet (gravity)
dictated the length of the pendulum to give 366 beats.
Simply brilliant!
