I recently watched two documentaries of relevance. The first was about the transformation of the Zeppelin Field at Nuremburg into the Nazi Party Rally Grounds by Albert Speer in the 1930s. Although the Germans were, and still are, no slouches when it comes to quality work, the parade buildings, which were constructed using cement products have either been demolished because of their danger to public safety, or are off limits for the same reason.
The second documentary was on the Cloaca Maxima. When you walk through the Forum in Rome you are walking over this tunnel. It was first built around 600 BC and completed in the time of Domitian. Not only did it fall into disuse, but the Roman civic authorities built another drain over the top of the Cloaca to stop the Forum from flooding and did not know that the Cloaca was underneath and full of rubble.
It is presently being cleared and is an impressive construction consisting of stone blocks, brick and, in places, a cement ceiling still in original condition.
So, we have modern cement products vs ancient cement products with a huge variation in quality. When did the Romans discover this high quality cement? Or, was it a legacy?
As far as the Great Pyramid is concerned, the core blocks appear to be have been quarried. However, the few casing blocks remaining may have been cast for a number of reasons - ease of construction at high elevations, precise abutments and ultra smooth surfacing. Maybe all those pounder types had a job pounding limestone and not granite.
With Puma Punku, again the larger slabs are sandstone which is soft and easily poundable. Some of those slabs weigh 100+ tons or more. We are told that they were transported from a quarry quite a distance away. How? Try
The H shaped blocks have already been documented as possibly being mass produced. More pounding? The glazed finish is interesting. Even at Giza some blocks exhibit this quality. And those odd shapes - those Cuzco refugees again? And why only one or two? Was Kafre's Temple recycled? Shades of Menkaure, old bean.
Sea travel may have been the conduit. Or, maybe the world was a smaller place. The largest flightless birds are the ostrich (Africa), the emu & cassowary (Australia) and the rhea (South America). Now, could they have all evolved separately? How could they have migrated by flight? Maybe they swam. Or, maybe they just stayed where they were and went along for the ride. Like those Titicaca guys in those Nile reed boats.
