Created by an anonymous young lady of London in the early 1800s to make the study of astronomy "familiar and amusing," the original constellation cards included in THE NIGHT A View of the Heavens, feature the constellations visible in the Northern Hemisphere. The sumptuous illustrations capture the inspiration of Classical mythology. The stars on the cards are perforated according to their relative magnitude, and when the cards are held up to the light, the natural appearance of the constellations is visible, making it easy for the viewer to pinpoint the constellations in the night sky.
