Moving Monoliths: Easter Island and Environmental Collapse
Rope
Strong thick cord made by twisting fibres of for example hemp together.
How did they put the wooden piles into the loch (UK)?
They sharpened the bottom end of the pile to a point using axes. They tied a cross piece of timber and attached it near the top. A person on either side of this cross piece could then twist back and forth to drive the pile into the bed of the loch.
