Diagram of a Stepped Lever Lifting Mechanism

A side-view engraving depicts a man in historical attire—a tunic, leggings, and a soft cap—pulling downward on a long rope. The rope passes over a horizontal beam mounted to a vertical post, which features a series of stepped, L-shaped brackets labeled A, B, C, and D. On the opposite side of the post, a pulley (F) directs a rope attached to a suspended, heavy stone block (E), with labels G, I, M, and N indicating the mechanical pivot points. The scene is set on a sparse patch of ground with minor vegetation, rendered in simple line hatching.

This image represents the 17th-century fascination with mechanical philosophy and the demonstration of physical principles through simple machines, typical of treatises on natural philosophy and architecture published in the early modern period.
