Above, a detail from a page in Athanasius Kircher's "Musurgia Universalis," printed in 1650. Snip from a post on Bibliodyssey:
A large part of the book is devoted to the history of instrumentation, including the anatomy of voice and hearing, and an extensive theory on acoustics entitled 'Magia Phonocamptica, sive de Echo', in which he described sound as 'the ape of light.'
Kircher professes the Boethian concept of musical harmonies' mathematical correspondences within the body, the heavens, and the natural world, and concludes with a discussion of the unheard music of the nine angelic choirs and the Holy Trinity. Kircher's research in music and acoustics led to many innovations and inventions, particularly in the area of amplification and sound design, which he would expand upon in his Phonurgia nova (Kempten 1673).
Other devices created the illusion of talking statuary, hydraulically powered mechanical music-playing automata, the aeolian harp (which was revived and venerated by the English romantic poets as a model of divine inspiration), the hearing aid, and the arca musarithmica: a primitive mechanical computer that would compose simple random compositions, as well as write messages in cipher, calculate the date of Easter in any year, and design fortifications.
