In Sept 2015 we asked for help from people around the world to perform an experiment
to coincide with the Lunar eclipse.
This experiment will test the hypothesis that our ancestors, at least as far back
as 5000 years ago, had all of the necessary tools available to them required to map
the accessible parts of the earth, to navigate great distances and to build temples
thousands of miles apart to correspond to or align with one another.
Conventional wisdom would have us believe that this was not possible, as it would
need the invention of accurate clocks. It was 1730 before we had a clock reliable
enough for navigational purposes.
Yet we seem to have an accumulation of evidence as we discover ancient temples around
the world seemingly located relative to one another over great distances, with an
architecture that indicates an awareness of accurately marking both time and direction
from the movements of the stars and the sun. Many temples also incorporate features
that reflect knowledge of lunar phenomena such as eclipses.
Maps such as the piri reis maps of the 15th century accurately depict coastlines
of both Europe and the Americas based upon ancient maps. What challenges conventional
wisdom is that these maps existed centuries before we developed the modern ability
to map longitude.
Is the evidence simply coincidental, an accident and a myth? Or were our ancestors
far more resourceful than we give them credit for today?
A few years ago Stonehenge Druid Frank Somers was working his way through observational
astronomy with the mind-set of identifying what it would be possible to discover
with just the human eye, human brain, some cord, some stones and the open sky. He
could see how measuring the movement of sunrise and sunsets between solstices worked
to divide the year into seasons, effectively a year clock. Essential for farming
and for organising social gathering. Identifying the equinoxes brought with it a
ground marker of true east west, from which true north and south could easily be
derived, allowing locals a sense of direction. Good for local point to point navigation.
But why go to all the trouble of studying the moon, to the extent that eclipses could
be predicted? What was the practical payback?
Frank did not believe that ancient astronomer priests the world over would go to
these extraordinary lengths of observation and time keeping just to spoof a magic
trick once every few years! ‘Look at me I have made the moon disappear!’. At the
same time the problem of how they might have solved the longitude problem bothered
him to the extent he couldn’t sleep at night until one day, after deciding to give
the problem up entirely, he realised that the two problems were related. The Lunar
eclipse is a tool necessary to solve the longitude issue.
He ran the idea past Sir Patrick Moore, a highly regarded British astronomer who
agreed that this must have been how the ancients had solved the problem and urged
Frank to conduct an experiment to prove it. Sadly, Sir Patrick passed away shortly
Ancient Tools required:
1. People : You and some friends to make the observation
2. A stone and some cord : essentially a plum line, a bit of string with a weight
at one end.
3. A wooden compass and some chalk or charcoal to make a star map : We can use a
pre printed version
4. Two or more accessible locations ideally many hundreds of miles apart from which
5. Knowledge of the arrival of next suitable eclipse
How the method works:
Everyone who has visibility of the moon when it goes into eclipse, sees the event
start to happen at the same moment in time. This means that in that moment, if all
observers were to look up at the sky following a plumb line, whatever position in
the stars directly above could be marked on their charts. Then the charts would need
to be labelled and returned to a common collection place, a journey maybe taking
years. When two observations are plotted to the master chart, the relative location
is known to both. For example if there were one observation made from the great pyramid
at Giza, and this was plotted next to the observation made at Stonehenge, it would
be known that Giza is located a set number of degrees southeast of Stonehenge and
so many degrees distant. The relative latitudes and longitudes of the two sites are
Of course the sky moves on turning so the specific stars are of no further interest,
but the distances and angles between sites can be plotted.and will not change. If
thousands of people dispersed to observe the eclipse along the coast line of Europe,
when their observations were combined, the shape of the map illustrated above would
Knowledge of the next suitable eclipse:
Where is it visible? If you are inside the area then you can take part!
As with all lunar eclipses, the region of visibility for Sunday's blood-moon lunar
eclipse will encompass more than half of our planet. Nearly 1 billion people in the
Western Hemisphere, nearly 1.5 billion throughout much of Europe and Africa and perhaps
another 500 million in western Asia will be able to watch as the Harvest Full Moon
becomes a shadow of its former self and morphs into a glowing coppery ball
What you will see:
Note that locations east of Britain the local time will be later in the morning of
28th, check your timezone, and in the Americas it will be evening of the 27th, check
your time zones!
Safety and disclaimer:
Please behave responsibly and put your safety first.
If you are venturing out, go with friends / adults, have appropriate clothing, a
torch, a phone etc and do not venture to anywhere forbidden by law or to any place
that might be for any other reason dangerous. Make sure people know where you have
gone and when to expect you back safely.
We do not accept any responsibility or liability for loss or injury if you take part.
By taking part you do so willingly of your own volition and entirely to volunteer
in the spirit of human cooperation, and you accept that we have no liability.
If you take part, you accept that you do so in the spirit of friendly goodwill, and
at your own risk and expense. We are not liable for, or offering to pay for the data
gathered, or for your time or for your expenses.
Sorry, but in these modern times these things must be made clear.
Step 1. Get everything needed together:
Download a copy of the star chart, we are using chart 2 and chart 3 to record the
location you observe yourself to be directly beneath at the time you observe full
eclipse begins (whole moon shaded & turning red).
Make a plumb line, a bit of string with a small ‘non sharp’ weight, such as a cotton
reel tied to one end. Just make sure when you are looking along it in the field
it cannot hurt you.
A pen or pencil.
Check the weather conditions & if clear, go to location where sky overhead and moon
are visible. Note, if cloudy you might decide to abandon the idea.
Step 3. Dry run
Before the moon eclipses it is a good idea to become familiar with the stars above
you and practice with the plumb line and chart at relating what you see to the chart.
If you have a star either due north or due south of you, that will help locate the
rough longitudinal region of the chart you are in (A compass or ground markers are
a bonus...our ancestors build monuments with north south alignments)
Step 4. Watch the moon!
When the moon is fully shaded and starting to turn red, that is your que to hold
your plumb line out, look up its length, compare the space above to the chart and
make a mark on the chart as accurately as you can. You need to complete this within
a couple of minutes to get really good results!
Step 5. Email us your results at email@example.com
The country, region, nearest place to where you made the observation
The actual longitude / latitude from a map or mobile phone if available for that
The longitude degree (nominal) taken from your observation using simple methods
The latitude degree (actual) taken from your observation using simple methods.
The local time when you made your observation.
Made up example of position overhead marked onto a chart. Nominal Longitude uses
the top most scale where 1 mark equals one degree. Count going right to left starting
zero under Nov 20 on chart 2
When the plumb line is free to find its own true, if you look along it from the bottom,
you are looking directly up.
