Title: Invisible Anatomy: Meridians and Math in Chinese Medicine

Abstract: This talk is based on Body Maps: Improvising Meridians and Nerves in Global Chinese Medicine, which reframes generic anatomical images by considering illustrations of invisible structures as maps. Body Maps offers a long global history of medicine through hand-drawn body maps and spans across the tenth to the twentieth centuries to re-think cultures of objectivity beyond normative geographies of science and medicine. In this talk, I focus on the graphic form of a tu 圖 as a historical category of technical images to understand how illustrations of lines guided diagnostic and therapeutic practice. Scholars often debated whether to discursively interpret these lines as meridians, channels, or tracts; practitioners often debated whether these lines merely visualized nerves to articulate needling and heating practices. Specifically, this talk offers a critical examination of a thirteenth-century image of jingluo 經絡, or meridians, and considers it within the epistemological frameworks of global East Asian medicine. Drawing on analytical approaches from science studies, visual culture, and medical humanities, it traces the aesthetic, conceptual, and political dimensions of these anatomical images across premodern, modern, and contemporary periods.
