This incredible technology was widespread in antiquity and evidence of it can be found in all corners of the world. Prehistoric builders used stones, the toughest surfacing material found on Earth to create perfectly round holes.
This impressive cutting-holes-in-stone technique reveals our ancestors were familiar with an extremely advanced technology we have long been unable to use.
Large-sized holes found in ancient stone demanded engineering skills and proper cutting equipment.
All kind of stones (even the hardest ones) were drilled for architectural, ritualistic or symbolic functions.
The hardness of stone did not limit the ingeniousness of the prehistoric builders!
For example, the ancient builders used a tube drill to hollow out the sarcophagus in the King’s chamber of the Great Pyramid.
They drilled off course and left a tube drill mark on the top inside of the box on the east side. They did some extra polishing to fix it up a bit but if you go to the King’s chamber you can still see it if you look carefully.
