Prehistoric stone circle discovered in Yorkshire

by Sean McLachlan on

A stone circle that was once part of a prehistoric cairn has been discovered by a group of amateur archaeologists on Ilkley Moor, Yorkshire, England.

A cairn is a large pile of stones that marked the grave of an important individual in prehistoric times. These stones were often taken away by later farmers for building walls or cottages, and sometimes all that’s left is a circle of stones from the base, as is the case here. The team says the cairn measures 27 by 24 feet. It would have been pretty high back in its glory days.

One stone had a man-made circular impression archaeologists call a cup mark. These are found all over prehistoric Europe singly or in groups, but nobody knows what they mean.

The UK countryside is full of ancient remains. When I was hiking along Hadrian’s Wall and the East Highland Way I brought along Ordnance Survey maps not only to find my way but because many prehistoric sites are marked on them. I passed stone circles, Anglo-Saxon ring forts, crumbled castles, and much more. Take these maps along to make your walk through the countryside a walk through history.

The Yorkshire team has made numerous discoveries in recent months. Archaeology is understaffed and underfunded, and dedicated groups of amateurs help take up the slack. Archaeological societies exist in many towns throughout the world and are a great way to learn about the past. While members are amateur in the sense that they don’t make their living as archaeologists, they’re often well trained and knowledgeable. This is important so that when they make their discoveries they don’t harm the very sites they are trying to study and preserve.

Exploring the tunnels under the Western Front

by Sean McLachlan on

The common image of the Western Front in World War One is of muddy trenches and artillery barrages. That was certainly the experience of most soldiers. But while huge armies slugged it out in the mud and ruin of France and Belgium, another war was going on underground. Sappers from both sides dug tunnels under enemy trenches, packed them with explosives, and blew them up.

The explosions were huge, like this one the British detonated under the German position on Hawthorn Ridge on 1 July 1916. The explosion used 40,000 pounds of high explosives and marked the beginning of the Battle of the Somme.

Sapping was extremely dangerous. Tunnels collapsed or got blown up by enemy mines. Sometimes mines intersected one another and there were hellish fights in the near darkness. Two good fictional portrayals of this war-beneath-a-war are the novel Birdsong by Sebastian Faulks and the Australian film Beneath Hill 60.

Now part of that underground battlefield is being studied by a team of British archaeologists. After detailed research in archives of several nations they’ve pinpointed a network of British and German tunnels under the French town of La Boisselle and have tracked down who fought there and when. They even know where some of these poor fellows got buried alive.

Right now the team is using ground-penetrating radar to map the tunnels and will being excavating in October. Some tunnels can still be entered while others are too unstable or have collapsed. Eventually the site will be opened up as a museum commemorating those who fought underneath the Western Front.

Genetic clue to Easter Island mystery

by Sean McLachlan on

Easter Island has always been a puzzle to archaeologists and historians.

Hundreds of miles from the nearest land, this small Pacific island hosted a culture that built the famous Easter Island statues, and then vanished as mysteriously as it appeared.

Now DNA evidence has shed new light on where the Easter Islanders came from. It turns out that while most of the islanders’ heritage has roots in Polynesia, as scholars have long believed, they also have some South American ancestry.

Norwegian scientist Erik Thorsby has found genes among Easter Islanders that are only in South American Indian populations. These genes had recombined with Polynesian genes, something that only happens after many generations.

The findings are tentative because Thorsby only tested one extended family but supporting evidence comes from an excavation in Chile that found evidence of Polynesian visitors in the 14th and 15th centuries. Given that the Polynesians were arguably the best sailors of the preindustrial world, they probably went lots of places we don’t know about.

Ancient migrations were more common than most people believe, and in recent years DNA evidence has revealed many anomalies not recorded in history. It’s best to be cautious, however. Some overeager researchers called hyperdiffusionists want to see all sorts of cultures coming from one source–the Greeks or the Egyptians or whatever their favorite happens to be. They tend to make unsupported claims about places like America’s Stonehenge, which is probably not ancient, and descend into New Age archaeology.

As Thorsby’s findings show, real science can be much more exciting than myth making.

Riddle of pyramid’s secret hieroglyphs solved

by Sean McLachlan on


Last month we reported on some secret writing discovered in the Pyramid of Cheops at Giza, near Cairo. A robot with a camera went down a mysterious passage only eight inches wide and found some hieroglyphs daubed with red paint onto the floor of a secret chamber at the end of the tunnel.

Egyptologist Luca Miatello has deciphered the writing and says they’re engineering marks. They make the number 121, which corresponds to the length in cubits of the so-called Queen’s Chamber of the pyramid.

The numbers are written in hieratic. Ancient Egyptian writing had three forms. Proper hieroglyphs were the most formal style and the one we usually associate with ancient Egypt. Hieratic was a cursive style that was quicker and easier to write. It was usually used for religious texts but since a royal tomb was a highly sacred place, it’s no surprise to find it here. Demotic was derived from hieratic and was used much later, after Egypt had lost most of its power and glory. All three styles are often termed “hieroglyphs”.

The numbers in the pyramid are sloppy, as if written by some foreman who wasn’t completely literate. Because of this, new interpretations of the writing will probably be published in the future.

Mystery mound in England turns out to be ancient monument

by Sean McLachlan on


England’s prehistoric landscape has a new addition.

Marlborough Mound in Wiltshire has long been a mystery. The flat-topped cone of earth looks like a smaller version of Silbury Hill, pictured here. The bigger mound was finished around 2300 BC at a time when Neolithic farmers were erecting stone circles such as Stonehenge and Avebury. Now archaeologists have taken samples from Marlborough Mound and carbon dated them to 2400 BC.

Carbon dating, which measures decaying carbon isotopes in organic matter, has a slight margin of error that increases the older the sample is. Thus Silbury Hill and Marlborough Mound may have been finished simultaneously, or at least in the same generation. The two mounds are only about 20 miles apart, a day’s walk for a Stone Age farmer or excited archaeologist.

The mound was reused several times. The Romans had a settlement next to it and the Normans built a castle on top of and around it in the late 11th or early 12th century. Early Norman castles were wooden palisades around an artificial mound. In this case their prehistoric predecessors saved them some work. The wooden walls were later replaced with stone ones but the castle has long since vanished. In the 17th century the mound was turned into a garden. The mound stands on the grounds of Marlborough College and is off-limits to visitors. Hopefully that will change now that its true importance is understood.
