Celestial navigational globe
Celestial navigational globe. Astronomical details on the sphere show that only the brightest stars are plotted, for a limited number of constellations. There are neither constellation figures nor contours of their areas. Above the title inscription, there is a labelled magnitude table in a rectangular cartouche. Some stars are marked by their Bayer notation. A total of 29 stars and one star group are named. There are the names of only 27 Ptolemaic constellations and three of the non-Ptolemaic constellations. One of the constellations of Hevelius is named.
A four-page pamphlet, English's Patent Star Finder, describing the use of the instrument, is present. In this, a letter, from a Capt. H.S. Blackburne to the inventor, Lieut. English, dated 26 April 1897, is reproduced in which he thanks English for sending the globe to him for inspection. Blackburne expresses his interest in the piece and commends it as a useful and accurate contemporary navigational instrument. For full details about the cartography and construction of this globe please refer to the related publication.
