Archaeologists claim that an ancient cylinder that has plagued experts for more than a century has been used for measurement since its discovery.
The old folk drum dates back to the Neolithic age and was found in a children's grave in 1889.
Since they were discovered
Covered with intricate carvings
Several generations of experts have been trying to find their uses.
Now, the researchers claim that this was used as a "standard measure" to plan the stone circles that our Stone Age ancestors built about 5 to 000.
Scroll down to watch the video, and Professor Mike Parker Pearson of University College London and Professor Andrew Chamberlain of the University of Manchester calculated the circumference of the potatoes.
When they began to think about the different weeks of the cylinder, they found that by winding the rope around each jar, the result was roughly a multiple of 0. 322 metres -
Just over 1 feet
Professor Chamberlain claimed that the distance was a stone age measure, which he called "long feet ".
They said that our ancient ancestors could use this method to create concentric circles on Stonehenge.
These patterned pots were discovered by an archaeologist before 2600, buried in a baby's grave, dating back to between 2000 and 130 BC.
Several generations of experts have studied the engraving and pattern of drums and drums in an attempt to understand their use, and most think they are decorative.
They are different from any other artifacts found in the UK, until a recent discovery of an undecorated chalk "Drum" in Lavant, Sussex, England ".
However, Professor Chamberlain and Professor Pearson claim that they are surprised to find that if you wrap a rope around all cylinders, they will get 3 measurements multiple times. 22 metres long.
For the largest cylinder, they find that if you wrap the rope around seven times, the measurement results are 10 long feet (3. 22m).
If you wrap it around the medium eight times
It is twice or ten times the smallest size, but it still has ten long feet (3. 22m).
This pot, which was later discovered in Lavant, was probably made by different craftsmen and also in line with this relationship.
Professor Chamberlain believes that drums are used as a portable method of defining length, which can be wrapped around a cylinder with a rope or rolled with a rope.
He said that although their findings will not be accepted by all archaeologists, he believes that the conclusion is much more likely than currently considered;
They built stone beams without using measuring tools.
Think about the stones used in Stonehenge.
Professor Chamberlain said that some of them came from far away.
"I don't think they're stupid enough to take these stones all the way to the site, try them and find them too short.
The discovery was reported in the British Journal of Mathematics history.
