The Temple of Flora, or Garden of Nature: A Group of Auriculas, 1803. Robert John Thornton (British, 1768-1837). Aquatint, stipple, and etching with watercolor added by hand; The greatest English botanical publication of the early 19th century was Dr. Robert John Thorntons Temple of Flora. Although Thornton studied medicine, his passion was botany and he soon embarked upon a major publishing venture that brought him both fame and financial ruin. The work, New Illustrations of the Sexual System of Linnaeus, was the most sumptuous botanical publication ever produced. The third section, the famous Temple of Flora, has 28 flower portraits set not against a plain conventional background but in the full richness of their natural setting. Unfortunately the day of the great florilegia had passed and Thornton died in poverty in 1837.
