Celestial Planisphere. This intricate chart shows the northern celestial hemisphere as known in 1690. Its pair, G200:3/3, shows the southern celestial hemisphere. They were produced in 1690 by mathematician Joseph Harris and publisher John Senex. Both include careful description of the construction of the charts and a series of examples and problems for how to use them. Edmond Halley’s Britannick Catalogue, on which this planisphere was based, was derived from a draft catalogue by John Flamsteed, the Astronomer Royal. Flamsteed had distributed it to fellow astronomers in 1686-7 on the understanding that its contents were too provisional for publication.
