Plate III of Thomas Heath's Popular Astronomy focuses on the Sun, solar spots, zodical light and it's magnitude as viewed from other planets. The page is comprised of printed diagrams as well as an early photographic view of solar spots through "high magnifying power."
This chromolithograph print was one of twenty-one plates published in Thomas Heath's 1903 edition of Popular Astronomy. The plates were produced by W & A.K. Johnston, Scottish brothers who set up their own printing business in Edinburgh after preliminary study under the Scottish globe maker James Kirkwood.
The prints produced for the Popular Astronomy offer a unique view of our understanding of the Universe at the turn ff the 20th Century.
