In 1739 China's emperor authorized the publication of a medical text that included images of children with smallpox to aid in the diagnosis and treatment of the disease. Those images made their way to Europe, where they were interpreted as indicative of the ill health and medical backwardness of the Chinese. In the mid-nineteenth century, the celebrated Cantonese painter Lam Qua collaborated with the American medical missionary Peter Parker in the creation of portraits of Chinese patients with disfiguring pathologies, rendered both before and after surgery. Europeans saw those portraits as evidence of Western medical prowess. Within China, the visual idiom that the paintings established influenced the development of medical photography. In The Afterlife of Images, Ari Larissa Heinrich investigates the creation and circulation of Western medical discourses that linked ideas about disease to Chinese identity beginning in the eighteenth century.

Combining literary studies, the history of science, and visual culture studies, Heinrich analyzes the rhetoric and iconography through which medical missionaries transmitted to the West an image of China as "sick" or "diseased." He also examines the absorption of that image back into China through missionary activity, through the earliest translations of Western medical texts into Chinese, and even through the literature of Chinese nationalism. Heinrich argues that over time "scientific" Western representations of the Chinese body and culture accumulated a host of secondary meanings, taking on an afterlife with lasting consequences for conceptions of Chinese identity in China and beyond its borders.
