‘The exhibition is made up of ‘The Planetaria from the scientific laboratory of Imola’s episcopal seminary’ complete with panels illustrating the fea-tures of the objects and the astronomical phenomena there represented. It is composed of three planeta-rio of great value, probably dating back to the first half of the 19th century, which respectively show the lighting of the Earth by the Sun; the solar system with its planets as far as Jupiter and their motions; the solar system with its planets as far as Uranus, the planetoids and satellites.’
