Likeness across Nature

Over the course of a long career, Hieronymus Fabricius of Aquapendente sought to train students and readers to think across nature. This article suggests that we read his program as inculcating an “anatomical eye”: a visual language of the body’s logic and nature’s intention that encoded knowledge, which expert anatomists derived from touch and sight combined. Fabricius both taught and learned haptically, observing organs’ divisions through variations in texture and measuring the differences in reproductive anatomy across animals with his fingers. Through dissections of sheep, cattle, horses, sharks, guinea pigs, dogs, and humans, he gathered details about how nature had produced both startling likenesses and particularities across the animal kingdom. While artists sometimes struggled to capture his experience, Fabricius’s longstanding commitment to working with them revealed that, whatever the challenges, the potential for expanding the “anatomical eye,” and the reputation that came with it, was worth the risk.
