The Arca was followed by, and closely related to another Kircher invention, the Organum Mathematicum, described by Kircher's pupil, Gaspar Schott.
Gaspar Schott wrote about the horned hare in his 1662 work "Physica curiosa", displaying it on the frontispice and with a further illustration.
The Organum Mathematicum was later described in a 1668 book of the same title by Gaspar Schott, who was Kircher's pupil.
