This chapter provides an abbreviated survey of sixteenth- and early seventeenth-century printed images of the interior of the eye, tracing the impact of illustrations of the eye in Vesalius’s 1543 De humani corporis fabrica libri septem through Johannes Kepler’s 1604 Ad Vitellionem paralipomena, quibus astronomiae pars optica traditur and Hieronymus Fabricius ab Aquapendente’s 1600 De visione. This is read against a persuasive narrative in recent historiography that posits clear differences between the impact of epistemic images in, on the one hand, the domains of medicine, anatomy, and natural history generally, and in the mathematical sciences, particularly astronomy, on the other. Vesalius looms large in accounts of the former, Copernicus and his wake (Tycho, Kepler, Galileo, etc.) in the latter. These studies in part responded to earlier, rather sweeping accounts of the importance of new kinds of graphic techniques, technology (print, foremost), and ways of seeing to the so-called Scientific Revolution. Such works, by, among others, William Ivins, Elizabeth Eisenstein, and Bruno Latour, made no clear distinctions between the visual traditions of medicine and mathematics.

Depictions of the interior of the eye, however, challenge aspects of both accounts. This chapter considers how entanglements of visual depiction, textual content, and experimental activities through developments in anatomy, medicine, and mathematical optics might revise broader narratives about the role of visualization in the development of modern science.

Metrication of Eye Illustrations in Vesalius

Though less famous than other now-canonical woodcuts in the Fabrica, within their domain Vesalius’s images of the eye exercised enormous influence.
