a walkthrough of a mechanical concept of the ancient world, that appears to be difficult to find a description of online.

1. How to lift big heavy rocks in
the ancient world
Just an idea, After all,, it could always have just been ramps.

2. An idea about how to place big rocks up high. No
this is not my idea, but I don't see it around
anymore.

3. Rock is on ground

4. Dig out under one side of rock

5. Rock rock by weighting the unsupported side

6. Place stone or log under rock, as close to center as
possible, but still on the raised sides half. Dig out
other side to allow rock to rock back into steep
angle.

7. Rock rock back to other side, over new, taller
point of rotation.

8. Place new log or stone to change point of rotation
to other side again,, fill hole with dirt to support
new point of rotation.

9. Rock rock again to other side.

10. Add new log, and fill with dirt to support the
new log,, repeat process until rock is lifted,,,
