Solving Stonehenge in the simplest way possible… Graphically.
Breaking free of the horizon 40-degrees from north at
Stonehenge, this is the maximum area of sky that the moon ever
gets to scan, and does so for several months every 18.61 years.
This, the moon’s most northerly point of rising, is called the
Major Standstill. The next Major Standstill should occur in 2024/5,
and if cloud free, should be quite an occasion for photographers!
But look what happens when we place the sun-arc on top of the
moon-arc - the moon commands a small section of sky - about
10-degrees, that the sun never gets to visit! - Not ever!
Stonehenge started
Stonehenge started its life as a simple circular-ish bank and
ditch. Bank here is shown green; the ditch is shown chalk white.
The northeastern causeway through the bank and ditch formed
an entrance passageway that completely spans and admits the 10-
degree portion of moon-arc, right up to the time of the Major
Standstill. So the first Stonehenge was dedicated to the moon.     
Let’s say that again...                                                                       
The first Stonehenge was dedicated to the moon.
Fifty-six pits set in a circle around the inside of the bank are thought to
have once held Welsh bluestones that later became earmarked for a
different purpose and were therefore eventually removed to be
replaced by dedicatory cremations. - So said Colonel Hawley who
excavated most of them.
W. Hawley, Society of Antiquaries, London 1926.

For now, though, let’s introduce just two of them – pit number 56 and
pit number 28. The bluestones placed standing upright in these two
pits helped retain the solstice sun clockwise and clear of the moon-arc
as shown.

56 Aubrey Holes
Shown on the left is the original henge-work as found by
partial excavation. Completing the full 56 Aubrey hole-
positions shows Stonehenge as it originally was; and
how it remained for the first 600 years of its life.

Mike Pitts, current editor of British Archaeology
Magazine, in an article, wrote...
If there is a full moon on the 21 June, the moon again will
be full on 21 June 19 years later, but at a different position
on the horizon. If the full moon starts over the Heelstone,
for example, it will slowly slip away each 19 year interval.
On the other hand, if you count 19, 18 and 19 years (a total
of 56), it will stay completely on the stone throughout many
It would seem that the Stonehenger’s had knowledge of
both: there are 19 stones in the bluestone horseshoe and
there are 56 holes in the Aubrey circle.

That should have been it, Stonehenge completed, but it clearly wasn’t: for if the simple intention was to
bring the sun and moon together, it was, as a sort of folly, clearly doomed to failure. So, after 600 static
years when little of importance took place, some massive sarsen stones were collected from the
Marlborough Downs near Avebury, to be set up in the very centre of the earthwork.
Stonehenge 2400 BC and a change of heart. - The stone circle
erected in the centre of the earthen bank and ditch.                   
It’s convenient at this point to imagine the sarsen circle as if it
stood alone, to demonstrate that there would be nothing to
stop solstice sunlight passing right through and out the back!
If, that is, the circle ever was complete!
Sarsen Circle
So, to prevent sunlight from escapimg,
the Grand Trilithon was offset by half-a-
megalithic-yard so Stone 55 of the
trilithon could block the sun’s progress
and prevent it from leaving.
Preventing sunlight from escaping in
this way, forced it to bounce around
Stonehenge’s flattened and polished
interior faces like a modern-day laser.     
But in order to believe this to be proven
fact, we will need to gather some extra
proofs of what others were doing
elsewhere at the time, and even many
years before. All these proofs will be
given in the fullness of time, some here
having been taken from my book:-

Stonehengeology 2012.
Avebury’s Cove. The following is how Avebury
began its life, and how we know for certain that
people of around 3600BC had used stones to
gather up sun and moonlight. People seen in this
photograph are identifying the ‘Backstone' of the
Cove by standing alongside it, but the surface
that faces the solstice and the Major Standstill, is
on the other side.
We also know, thanks to the Ordinance Survey,
that the Cove once stood in the middle of a
geometric stone egg - and that egg was aligned
both on the Vernal equinox and Cherhill Hill.

Avebury's Cove 2007.
The Cove originally consisted of three stones set
perfectly rectangular and at 90-degrees to one another.
So by placing the camera to respect one side of the
rectangle, produces a photograph that proves the sun to
fall 5-degrees short of the Cove, and the moon to go
5-degrees past.
The Major Standstill is conveniently marked by the druid
who helpfully demonstrates where the moon will appear
every 18.61-years, given good weather.
With ideas carried down from earlier work
conducted on Windmill Hill - this was the
original, and very first Avebury...
Placed in the middle of one of Professor Thom's
Type 2 eggs, as seen in
Megalithic Sites in
Britain, A. Thom. 1967.
And; with Barley seed
placed around the base of the Cove-stones;
Avebury: Gillings and Pollard 2005, it was hoped
the Cove would act like the tungsten filament of
a bulb and energise the whole thing.
The egg was aligned on the Vernal equinox
because that is the one time when the sun and
moon go to ground in the same place, which in
this case
, is the notch in the horizon at the
northern end of Cherhill Hill.
Avebury's idea of aligning a monument on the
equinox was later copied by the Stonehenger's
when they built the 3.5 kilometre-long Great
Cursus, in front of what, some 500 years later,
would become Stonehenge.

This final picture places Stonehenge's stone circle
in the middle of the earthwork where it belongs.
There is much that can be said about this image, but
to do so would be to miss the big picture: for it was
at about this time, around 2400BC that Stonehenge
was joined to a wooden egg in the middle of a
massive henge, some 500 metres in diameter, and
known as Durrington Walls, by two avenues and a

We owe the background image to John Wood, who
surveyed Stonehenge in 1740 and graciously passed his
measurements down to us.
John's feet and inch measurements were converted into
Professor Thom's megalithic yards before entering them
into CAD at the rate of one MY equaling 32.664 inches.
The 10 degree angular difference between the Sun and Moon
This figure represents the maximum amount of sky that the sun
ever manages to scan at Stonehenge. The sun breaks free of the
horizon 50-degrees from north on the 21st June and manages to
scan a maximum 260-degree of sky from sunrise to sunset.
Everyone who visits Stonehenge to see the morning solstice,
looks out along this 50-degree angle from north.
