Instrument zum Ermitteln eines parabolischer Bogens

This engraving depicts a geometric instrument designed to trace the path of a parabola. Small pins are placed at specific coordinates, with a cord or rod used to demonstrate how mathematical curves can be generated through physical motion. The letters serve as a reference for the accompanying Latin text found in Athanasius Kircher's scientific treatises.

Athanasius Kircher viewed geometry as a divine language that governed the physical world, from the paths of projectiles to the reflection of light. This diagram represents the 17th-century Jesuit effort to synthesize mechanical invention with natural philosophy, bridging the gap between Renaissance magic and experimental science.
