Johann Adam Schall von Bell
The Museo della Specola Bologna has in its collection, displayed on the wall of the Globe Room, original copies of panels 1 and 6 of the six panels comprising the 1602 Ricci map. During restoration and mounting, a central panel—a part of the Doppio Emisfero delle Stelle by the German mathematician and astronomer Johann Adam Schall von Bell—was inserted between the two sections by mistake.
