There is no official record of a cat organ actually being built; rather it is described in literature as a bizarre concept. This supposed instrument was described by the French writer
Jean-Baptiste Weckerlin in his 1877 book ''Musiciana, extraits d'ouvrages rares ou bizarres'' (Musiciana, descriptions of rare or bizarre inventions): The instrument was described by German physician
Johann Christian Reil (1759–1813) for the purpose of treating patients who had lost the ability to focus their attention. Reil believed that if they were forced to see and listen to this instrument, it would inevitably capture their attention and they would be cured: "A fugue played on this instrument--when the ill person is so placed that he cannot miss the expression on their faces and the play of these animals--must bring Lot's wife herself from her fixed state into conscious awareness." The instrument was first described by
Athanasius Kircher in his 1650 work
Musurgia Universalis, though the lack of an image may have left doubt in the minds of some writers. (
The New York Times, for example, has carried an article claiming he described the instrument, and another stating he did not describe it in
Musurgia Universalis.). His description appears in Book 6, Part 4, Chapter 1, under the heading "Corollaria," (emphasis added): This can be paraphrased as: The citation is noted by Kircher's student
Gaspar Schott in
Magia Naturalis naturae et artis, Part 2, Book 6, Pragmatia 2, titled "Felium Musicam exhibere [Cat Concert]." == Modern citations and reconstructions ==
