One of a set of teaching cards published by James Reynolds & Sons, London, England around 1860. Titled 'Telescopic View of the Moon', the chart was drawn and engraved by John Emslie. The astronomical diagram shows the appearance and lists the physical characteristics of our nearest neighbour in space. This Moon map illustrates both the difference in brightnes of the lunar surface along with the form and shape of the lunar mountains and craters. These are shown together for clarity as the former is best been when the Moon is full while the latter is most clear when the Moon is half lit.
