This wonderful device was used to solve problems concerning the calendar, tide tables, the rising and setting of the sun, moon, or stars, and the positions of planets. It consists of a separate movable paper disc, engraved with the signs of the zodiac, rotating on a red satin ribbon pivot in a graduated circle engraved with 29 divisions. These were included in scientific books and atlases and because of their delicate nature most have not survived in tact.
