[Phidippides]

I wonder if there is anything published which specifically looks at the parallels of the history of engineering in the West and in the Americas.  Probably.

A water feature found in the Maya city of Palenque, Mexico, is the earliest known example of engineered water pressure in the new world, according to a collaboration between two Penn State researchers, an archaeologist and a hydrologist. How the Maya used the pressurized water is, however, still unknown.
