Rock with ancient star shaped drill holes found in the UK (Dartmoor).
“The Hound of the Baskervilles” tale takes place in the moors. The Dartmoor National Park may not have crazy dogs roaming the place today, but it does have signs of ancient, advanced drilling. Star-shaped drill holes to be exact.
Sir Arthur Conan Doyle’s character, Sherlock Holmes would not be able to solve how star holes were created in stone with his deductive reasoning because the technology of ultrasonics did not exist during the Author’s lifetime.
Today, we the advanced lapidary artist understand how these star holes were created in rock by using the process of elimination.
To understand how ancient drill holes were created in solid rock, you don’t need intelligence, you need wisdom.
Wisdom to know what works and what doesn’t work.
When you have eliminated the impossible, then whatever remains, however improbable, must be the truth.
Star shaped drill holes were created in the distant past (in pre-history) using ultrasonics.
And that’s no shit, Sherlock.
