Anatomical illustrations form the foundation of medical education and clinical understanding. They convey precision and scientific objectivity and often appear timeless and neutral. However, many of these images were created under social and political conditions, which have long been ignored.

Drawing on British anatomical history and legal developments, Lucy E. Hyde, an anatomy lecturer at the University of Bristol in Bristol, England, argued that anatomical images extend beyond scientific representation. These images encode the historical context of their creation.

Early Foundations

The connection between anatomy and societal structures dates back centuries. The first documented human dissection occurred in Alexandria around 300 BC. In the second century AD, the Greek physician Galen established anatomical principles that shaped European medical understanding for centuries, based on animal dissections and observations of injured gladiators.

In medieval Europe, the dissection of human bodies remains rare and highly ritualized. A shift appeared during the Renaissance when empirical observation was combined with artistic representation.

Around 1500, Leonardo da Vinci produced detailed anatomical studies that integrated scientific precision with artistic forms. In 1543, Flemish anatomist Andreas Vesalius introduced a new visual framework in De Humani Corporis Fabrica. His figures appeared muscular, idealized, and depersonalized, demonstrating that anatomical illustrations reflected cultural norms rather than purely objective observations.

According to Hyde, although anatomical realism improved in the 17th and 18th centuries, the underlying social conditions did not change. Anatomical specimens were sourced from socially disadvantaged individuals.

Ethics in Focus

One of the most controversial examples is the atlas of Viennese anatomist Eduard Pernkopf. Beginning in 1930, during the Nazi era, the atlas remains recognized for its precision, particularly in depicting complex nerve structures. However, many illustrations were based on the bodies of executed prisoners.

Decades later, the atlas continued to be used in surgical practice, prompting a debate within medicine and ethics about how to manage anatomical knowledge from a problematic historical background. Hyde emphasized that these images function not only as technical tools but also as historical records.

Earlier studies have shown similar concerns. William Hunter’s 1774 atlas The Gravid Uterus, which advanced obstetrics, was based on the bodies of 14 pregnant women. The identities and circumstances under which their bodies were obtained remain unclear. During a period of limited legal access to cadavers, illegal procurement is strongly suspected.

The women were anonymized, with their identities and life histories absent, showing how anatomical images can produce scientific knowledge while erasing the individuals behind them from historical memory.

Law and Inequality

Access to anatomical specimens for medical training is a persistent structural challenge. While the British Murder Act of 1752 allowed the use of bodies of executed criminals, this supply did not meet demand. In many cities, a black market called “Resurrectionist” exhumed bodies emerged, often targeting poorer individuals whose graves were less secure. Wealthier families could protect their dead with guards or secure burial sites, while socially disadvantaged people had little protection, even after death.

The Anatomy Act of 1832 reduced illegal trade but introduced institutionalized inequality. It allowed unclaimed corpses from workhouses, hospitals, prisons, and psychiatric institutions to be used for anatomical studies.

Individuals without family or financial resources were disproportionately represented in the anatomical collections. According to Hyde, this development shows that advances in anatomy have long depended on the systematic use of the bodies of socially disadvantaged individuals.

Only in the late 20th century did informed consent begin to take hold, shifting the use of human bodies from institutional assumptions to voluntary decisions. The British Human Tissue Act of 2004 set up clear legal standards and made voluntary body donations the foundation of modern anatomical practices. Despite this shift, many historical images remain embedded in contemporary medical culture.

Modern Implications

Despite their debatable history, many illustrations remain in use. Their graphic precision is widely regarded as exceptional, and some clinicians still consider them valuable, particularly for complex surgical procedures. However, Hyde noted that using them without context is problematic as it risks silencing the individuals behind the images. When these depictions are presented without reference to their origins, the bodies are reduced to anonymous objects of scientific inquiry.

The positions in this debate vary widely. Some argue that clinical value can justify the continued use of these images if their historical origins are clearly acknowledged. Others view their use as a continuation of the inequalities inherent in their creation. This divide proves how closely medical practices remain tied to historical and ethical considerations.

Contextualize, Replace

In response, institutions and educators have adopted a more deliberate approach to historical visual material. Courses increasingly combine older illustrations with critical analysis, archives research the provenance of their collections, and medical illustrators create new image series based on documented consent. The goal is to build a visual culture that combines scientific precision and ethical responsibility.

Digital technologies are advancing this shift further. Modern anatomical image libraries aim to represent a broader diversity of bodies, including different genders, skin tones, and body types. However, international standards for handling historically problematic illustrations are lacking. As a result, many images continue to circulate without context in teaching materials and online sources.

New Perspective

Within this context, Hyde argued that anatomical illustrations should be viewed not as neutral tools of knowledge but as historical records that require accountability. Anatomy depends on accuracy, but precision alone is insufficient. It also matters how knowledge is presented and whether individuals whose bodies make that knowledge possible remain visible.

Anatomical illustrations do more than depicting the human body; they also reflect the time in which they were created, revealing medical ambition, artistic development, and the often-overlooked realities of those whose bodies became teaching sources.
