Spiralförmiges Sprachrohr

The image depicts a tapered acoustic instrument with a distinct spiral or 'snail-shell' torsion along its body. Labeled with 'A' at the narrow mouthpiece and 'B' at the wide bell, the design was intended to demonstrate how geometric forms could amplify and transmit the human voice.

Athanasius Kircher was a pioneer in the study of acoustics, which he viewed as a branch of 'natural magic'—the application of scientific principles to create wondrous effects. This device reflects his broader philosophical goal of understanding the hidden harmonies of the world through the physical properties of sound and light.
