This wooden model, created in 1844 by P.N. Rijk, depicts a double-threaded Archimedean screw propeller, a device used for propulsion in water or air. The model, painted in blue and white, stands on a wooden base and features a brass shaft extending from the propeller. This detailed model demonstrates the intricate workings of the Archimedean screw, a principle discovered by the ancient Greek mathematician Archimedes, and its application in engineering.
