Richard Anthony Proctor - Antique Celestial Map, “On the Stereographic Projection”, 1880. “This Celestial Map is showing all the space covered by the six Northern Maps. On the globe the circle 1, 2, 4, 6, 8 and 10 are equal to each other, and also to those circles to which the overlaps 3, 5, 7, 9 and 11 belong. The dates around the Map are those on which the corresponding Meridians come to the South (in Northern Latitudes) at midnight.”
