original: "λ" (lambda). Leonardo frequently used Greek letters as variables to designate specific points, lengths, or weights in his mechanical diagrams.

A pen and ink sketch depicts a mechanical frame, likely a study for a hoisting device. The drawing features a trapezoidal structure with internal circular elements representing pulleys or pivots, alongside a vertical member on the right side. Mathematical or proportional notations in Leonardo's hand appear below the diagram.
