Object Literature
In astronomy, a planisphere is a star chart analog computing instrument in the form of two adjustable disks that rotate on a common pivot. Made in Germany for George Philip & Son, this beautiful object is printed with the constellations in the night sky and the days of the year around it. On the back is a printed explanation of how to use the planisphere with a small publisher’s advertisement at the bottom for other astronomy publications. This is the earliest version of this model.
This beautiful instrument is both a rare collectable and a decorative delight.
