I think the Archimedean screw was probably attributed to him, but antedates him by some years. The Egyptians didn’t invent it, apparently, they used (in ancient times, and still do) the shadoof (sp?).

I thought the Egyptians used the same type of device/technology to raise the Pyramids. One look and you can see how screwed up they are. Shadouf, shadouf, bod-da-da bod-da-da, shadouf, shadouf

I recall a TV program where they attempted to recreate ancient technology, and they reached the conclusion that a water screw was the only way the Hanging Gardens of Babylon could have been watered.

A Shadoof system might have delivered the volume, but the whole structure would have looked like a building site, cranes and workers instead of vegetation. Whereas a waterscrew system would have been visually non-obtrusive, and the workers could have been hidden below ground.
