The bluestone of Stonehenge was migrated?

 　　When it comes to "Stonehenge", everyone is familiar with it, and there are many related studies. Earlier in 2021, the publication of the findings of the Stonehenge project by Mike Parker Pearson and colleagues at UCL caused a media sensation. To determine the origin of Stonehenge bluestone (the smaller stone, not the larger one), the scientific team led by Pearson has been researching for a long time. Using geochemistry to analyse the elemental composition of the stone pillars, Pearson's team confirmed that the bluestone came from the Karn Godog and Craig Rose Evelyn quarries in West Wales, Presley Hills.

　　Previous research suggests that at least some of the bluestone must have come from quarries in and around Cammenin in the Preseli Mountains. But rumor has it that the stones were first erected locally before being transported to their final destination on the Salisbury Plain, 282km away. This statement seems to be derived from Geoffrey's History of the Kings of Britain (c. 1136 AD). He claims they originally erected a monument in Ireland called the Dance of the Giants. Although none of the stones came from Ireland, in Geoffrey's time west Wales was considered Irish territory. Will there be ancient remnants of memory in this story?

　　Petrology corroborates the fact that the bluestones came from the Preseli area, where many prehistoric megaliths indicate that it was a revered landscape during the Neolithic, supporting the possibility that these stones were originally used as megalithic monuments. Many modern researchers have pondered this question. In the past decade, Pearson et al have discovered quarries in Preseli.

　　While searching for a possible Preseli original site for bluestone of a similar age, they eventually found a site about 6.5 kilometers northwest of the Cammenin Ridge. Careful excavation uncovered 6 stone caves (one of which may have housed 62 bluestones from Stonehenge), these holes and surviving stones allowed researchers to calculate the original monument was 110 meters in diameter, with the circular ditch surrounding Stonehenge. same diameter.

　　Further research also suggests that ancient builders may have built a temporary structure at Karn Godog before the columns were brought to Salisbury Plain. Therefore, the researchers believe that these bluestones may have been "marks of ancestral identity" that were eventually migrated to what we call Stonehenge. As for why it's there, for what reason? Then it is unknown.

　　This groundbreaking discovery proves that people have been quarrying stone since 6000 BC, and that bluestone was mined to build stone fences. Bluestones, known for their beautiful shades of blue, were known in ancient times not only for their color, but also because of their abundance in quarries like Karn Godog and Craig Rose Evelyn popular.

　　Pearson's team also found that ancient builders used softer mudstone or sandstone wedges (found at excavation sites) as tools to avoid damaging the natural stone pillars. These tools play an important role in transporting the boulders to their final destination.

　　As for whether it is possible to transport stones from the quarry to hundreds of kilometers away, there is evidence that 10 people can easily move the pillars at more than 1.6 kilometers an hour by pulling the pillars in the right location.

　　This plausible explanation may finally be the theory needed to solve the centuries-old mystery of Stonehenge's existence.
