Natural history illustrations often aim to show life-like flora and fauna. Depictions of birds poised to take flight, fish swimming upstream, and mammals mid-stride are common in 18th and 19th century zoology and botany publications. What is lost in these often lavish illustrations is a certain truth about the way many naturalists interacted with their objects of study: many species of plant or animal were first encountered not in the wild, but in the display case, in the form of carefully prepared specimens.

One British naturalist, Captain Thomas Brown (1785-1862), made the practical observation that mounted animal specimens allowed naturalists to “contemplate, without dread, the most destructive and furious quadrupeds, and the most noxious reptiles.”

As a commemoration of the Imperial collection of shells in Vienna, the printed folio of Testacea Musei Caesarei Vindobonensis of 1780, is splendid. The eighteen engraved plates, carefully colored by hand, render individual specimens in the Habsburgs’ K.K. Hof-naturalien-Cabinet as if pieces of jewelry, casting shadows on a plain background of the thick, hand-made paper. Dedicated to the Empress of Austria, Maria Theresa (1717-1780), this production was also a work of science, as the task of arranging the shells in the Cabinet and describing them for publication was given to one of the leading scientists of the day, Ignaz Edler von Born (1742-1791).

In 1737, Elizabeth Blackwell published the first weekly installment of a very ambitious project. The final work, entitled A Curious Herbal (1737-39), ultimately consisted of 500 plates of plants alongside 111 pages of text providing descriptions of their medicinal uses. Endorsed by the Royal College of Physicians, the publication helped satisfy the need for an up-to-date reference work for apothecaries.

A Curious Herbal is the subject of a chapter in Dr. Anna K. Sagal’s first monograph project, Resisting Gardens: Pedagogy and Natural Philosophy in Eighteenth-Century Women’s Work. By providing free, online access to relevant literature, such as Blackwell’s Herbal, the Biodiversity Heritage Library has been an important resource for Sagal’s research on the project.

Armed with rOpenSci’s packages binding powerful C++ libraries and open taxonomy data, how much information can we automatically extract from images? Maybe not much, but, experimenting with gorgeous drawings from a natural history collection, we can least explore image manipulation, optical character recognition (OCR), language detection, and taxonomic name resolution with rOpenSci’s packages.
