On the Force of Percussion

An allegorical frontispiece engraving. On the left, a seated female figure wearing a winged helmet, likely representing Mercury or Science and Reason, sits at a stone plinth, holding a pair of compasses over a geometric diagram and a globe. Behind her is a large classical column and draped fabric. To the right, another female figure, partially draped and wearing a floral wreath, stands in a landscape, gesturing toward the first figure. In the lower left foreground, a large thistle-like plant grows. The central text is inscribed on the face of the stone plinth.
