The sites visited and photographed by Hartt for the works on view—among them, the historic university cities of Leiden, Uppsala and Göttingen—were informed by the work of artists and early naturalists active there, primarily, but not exclusively, during the 18th century. Through mostly close-cropped, nondescript views, however, locations are kept from being fully identifiable in the images. Their titles are the primary indicator, parenthetically noting the city and date of the photograph, as well as the scientific names of the plant species featured in it. Documents of a place and a specific moment in time, they also refer to and enact a process of naming. Swedish botanist Carl Linnaeus, known as the “father of modern taxonomy” for having formalized the binomial nomenclature system in 1753, is also associated with three of the cities in which the photographs were taken. The presence of such figures puts the images in dialogue with European artistic and intellectual traditions in and around this period—a period also marked by European colonization and its effects, including the movement of flora, fauna and human communities.
