Original fileExperiment zur Darstellung des Luft- und Wasserdrucks
The image depicts a physical experiment set on a flat surface. A cylindrical basin is labeled with points A and B at the rim, and C and D at the base. Water flows into the basin from a nozzle shaped like a ram's head. Inside the basin, two vertical tubes are visible; one (labeled E) descends into the lower portion of the vessel, while another (labeled F) is connected to a vertical whistle (G) extending upward outside the basin. The style is a clean line engraving typical of 17th-century natural philosophy texts, focusing on the mechanical components of hydraulic and pneumatic pressure.
This illustration originates from Robert Fludd’s 'Utriusque Cosmi Maioris scilicet et Minoris metaphysica, physica, atque technica Historia' (1617). It serves as a visual demonstration of Fludd's early modern investigations into natural philosophy, specifically the interaction between hydraulic forces, air displacement, and sound production.
Experimentum II. A B F E C D G Aqua cadens in superiorem regionem vasis A. B. C. D. descendit in regionem ejus inferiorem per tubam E. & expellit aerem in ea contentum per foramen tubae, F. qui transiens per orificium fistulae. G. eam flatu suo resonare facit.
Translation
Experiment II. Water falling into the upper region of the vessel A. B. C. D. descends into its lower region through tube E. and expels the air contained therein through the opening of the tube, F. which, passing through the orifice of the whistle, G., makes it sound with its breath.
