This scientific illustration titled "The Earth's Shadows" (No. 58) was published in The Beauty of the Heavens by Charles Blunt in London in 1842. The diagram shows the geometrical formation of the Earth’s shadow cones — the umbra and penumbra — cast by sunlight during lunar eclipses. The composition clearly illustrates how the sun’s rays are partially and fully obstructed by the Earth, using intersecting lines and tonal shading to distinguish light paths and shadow zones. With its minimalist yet precise aesthetic, the plate conveys core astronomical principles with clarity, intended for educational use in an era when visual explanation was key to public understanding of science.Charles Blunt (1803–1878) was a British educator and scientific writer best known for his contributions to popular astronomy. His work sought to make complex astronomical concepts accessible to general audiences through both text and engaging illustrations. The work was published by Whitehead ; Co. in London in 1842.Artist or Maker: Charles BluntDimensions: 25 cm x 20 cmMedium: Hand-Coloured Aquatint EngravingDate: 1842Condition Report:This work is in good condition overall.
