Recirculating Water Pump (Rezirkulationsmühle)

This black-and-white print illustrates a mechanical pumping system where an external water wheel drives an internal vertical shaft. The shaft rotates two horizontal gears (labeled F and G) that interact with pinions (H) to move a chain suspended in a cylindrical shaft (A). The chain features a series of circular leather discs (C) that lift water from the basin (B) to an elevated trough. The image is a technical cutaway view, heavily annotated with letters indicating the mechanical components, set against a background of wavy lines representing water.

This illustration originates from Robert Fludd's encyclopedic work 'Utriusque Cosmi', specifically the volumes on mechanical technology. It represents the early modern transition toward mechanical philosophy and the application of water power in Renaissance engineering.
