Abstract

The article suggests methods that allow creating the most complicated type of polygonal masonry found in Peru. This masonry consists of large stone blocks weighing from several hundred kilograms to several tons fitted close to each other almost without a gap between complicated curved surfaces of large area. The work provides a description of techniques, which apparently were used by builders who arrived from Europe. The techniques under discussion are based on the use of a reduced clay model, 3D-pantograph and replicas. The use of a reduced clay model and a pantograph provides not only the unique appearance and high quality of masonry with large blocks, but also allows to significantly increase the productivity of the builders. As machines copying three-dimensional objects are known since the 18th century, the stone structures under consideration should be dated by that and later time. The remaining simpler types of polygonal masonry with smaller stones or fitted surfaces are almost flat, or stones contact with each other by a small area, or there are significant gaps between stones, are quite consistent with the well-known methods of stone processing of those and earlier years, and, therefore, they do not require any additional explanations.

Comment: The article fails to convince me of the plausibility of these huge monuments being built by Europeans. Recorded history would have captured such monumental efforts. The article itself also raises the questions of funding and necessity for building such structures. Which the articles unsuccessfully tries to explain away. While the article is an interesting effort at finding solutions to the mystery, I think we are not yet sure of the origins of these works!
