Stonehenge in England is famous for its Saracen "Sarsen" Stone Circle. Why it was originally built after 2600 B.C. is difficult to prove but the sky probably played at role (Gerald S. Hawkins). But there is something about Stonehenge most people don't know and that is a ring of 56 holes named after John Aubrey (1626-1697) to whom their discovery is vaguely attributed. The Aubrey Holes are older than the Sarsen Circle dated to the first phase of Stonehenge at 3100 B.C. And it is this circle of holes where there is some stunning astronomical information.
The Aubrey circle has a diameter of 283.5 feet and a circumference of 891 feet. The ratio is 22/7, but it is not known if the unit of measure was the foot. In fact, there is another unit which makes more sense, the elbow or "ell". If we take an elbow length of say 18 inch straight from the anterior crease to the tip of the middle finger, then the Aubrey Circle has a diameter of 189 ells and a circumference of 594 ells. 594/189 is 22/7. And with these two measures on the concourse, one in units of Aubrey Holes, and one in units of ells, we find some incredible astronomical counts which predict where the Moon will be on the ecliptic Zodiac, when the Moon will eclipse the Sun or the Earth will eclipse the Moon, and when the Moon will look the same on the same day of the year.
The way the counts work is like a Modulo. Each time around the circle is "1". What doesn't add up to a full circle is the Modulo's Remainder. For example if you perform a Modulo operation on the number 100 with a Modulus of 33, you get 3 x 33 = 99 and the remainder is 1. So the MOD33 of 100 is equal to 1. And so it is these remainders which I have plotted on the Aubrey Circle for the various lunar super-cycles
But the real surprise here is that if you apply the Aubrey circle as either a MOD56 or a MOD594 to the various known lunar cycles in either days or months, the remainders end you up where the circle is specially marked with marker stones, barrows, and stone holes. And it is these markers which confirm that this circle was indeed meant to be a lunar clock to predict the Moon in the distant future, A Moon Clock of the Ages.
