Apology if this aspect was reffed by another in this excellent thread.
The modular looking H blocks at Puma Punku have several web articles
and net forum discussion on them being ancient cast modular
With ratio mix knowledge/form making and knowledge of cuering
time for various block sizes.
Its possible these huge slabs noted in your main thread and
other world sites
Are outcome of this modular casting practice which goes back
in time....how far? : )
This knowledge may indeed exist prior to the chaos period
which caused global upheavels
with survivors migrating as world oceans rose.
It may also be the case for mineral/metallurgy and alloy.
The knowledge moves with survivors and becomes inactive
renewed in certain locals as per resource and instrumentality
Some ancient stone temples and palaces were clad with sheets
of Gold/Copper....other softer work metals which shined.
If one could fashion rollers which were adjustable
One could then manufacture the sheet cladding.
This too...an ancient manufacture/engineering side which
was renewed and used by those with resources and the understanding
of the concept.
Ancient world ocean transit...trade...would be a medium for
engineering knowledge to travel.
People witness the engineering and duplicate that where they
Not exactly in all cases....as building designs are different
