Too precise for hand tools? The argument from ancient craftsmanship
Cassie Coppersmith points to jade pieces and Indian pillars that look machined or lathe-turned, Dan Richards examines the Great Pyramid's precision and how it could have been achieved, and Timothy Alberino questions who could have cut Peru's megaliths. The argument recurs across very different cultures, so it is worth seeing what it proves and what it only suggests.
What is the argument from ancient craftsmanship? Show answer
The work looks too precise for the tools and dates assigned to it, so the tools, the dates or both must be wrong.
What do the observations actually establish? Show answer
Real puzzles, mismatches between fine and crude work, and gaps in standard explanations, but not measured precision, tools or makers.
Why does Cassie Coppersmith doubt the conventional account of the jade pieces? Show answer
An experiment drilling jade with bamboo left thick, uneven lines, while the artifact's lines are fine and tightly spaced.
What weakness does Coppersmith admit about the jade claims? Show answer
She does not know to what tolerance the discs are flat and says there have been few deep studies of their precision.
What do archaeologists concede about the Indian pillars, on Coppersmith's account? Show answer
That they were lathe-turned. They suggest the lathe was human or animal powered, not a machine.
What is Coppersmith's point about inscriptions? Show answer
A king's inscription dates the inscription and shows his presence. It need not date the structure it is written on.
What number does Dan Richards start from? Show answer
The Great Pyramid's sides of about 756 feet are squared to within roughly two to three inches.
Why does Richards reject lost high technology? Show answer
No tools have been found. He wants mundane explanations exhausted before harder speculation.
What is Timothy Alberino's strongest argument about Peru? Show answer
The Spanish never had the Inca teach the technique, and their mortared cathedrals collapsed in earthquakes while the older walls stood.
What does fine work beneath crude work show? Show answer
That the fine work probably came first. It does not show how much earlier or how it was made.
Who is missing from these conversations? Show answer
Any archaeologist, stonemason or engineer who works with these materials. The standard view is reported only by its critics.
What should you ask when something is called perfectly flat or square? Show answer
To what tolerance, and whether anyone has actually measured it.
