Stone Shifting 3

Egyptian obelisks are raised on plinths. They usually have a "turning" groove across the back edge of the plinth stone, implying that they were rotated upright either by ropes and A-frames, or wedges, or levers, or a combination of all three. A turning groove is only effective once the obelisk reaches a reasonable angle (say 30 deg or more), so it is likely that it was initially lowered onto the plinth from the top of a ramp. This was probably done with a sand-filled enclosure which was dug out from holes at its base to allow the obelisk to descend slowly onto its plinth. The ramp would also be a good foundation against which to wedge or lever the obelisk to vertical, perhaps with ropes to assist.

It seems unlikely that the people of Easter Island would have used sand boxes to raise their statues, but if they are on plinths, it is possible that they were loaded onto sledges in an upright position for transportation. Maybe the raw stone was put on its sledge before being sculpted, in which case an upright position would be an advantage. This might also explain why the timber was not recycled. It probably took a long time to sculpt the statues, so perhaps many were on the go at once, each occupying its own sledge for the duration.

Presumably the archaeologists know (from the debris) where the heads were quarried and sculpted?

In Thor Heyerdhal's book "Aku-Aku" there are descriptions and pics of the Islanders raising a fallen statue back onto its plinth using levers and a support of rocks and pebbles to get it upright.
Interestingly, when the ends of the levers got out of reach, ropes were attached and and pulled on from the ground.
As remarked on here, this did not "Prove" this was how it was done originally, only that it was a method that worked.
Most of the existing statues are much smaller than the aborted 60 footer. (Book not to hand at mo so can't check exactly)
