Why were human dissections restricted in many ancient and medieval societies?

In many ancient and medieval societies, human dissection was significantly restricted primarily due to prevailing social and religious taboos against the mutilation of the human body. These cultural norms viewed the desecration of a corpse as morally and religiously reprehensible, which discouraged the practice of human anatomy studies.123

Because of these prohibitions, physicians and anatomists—most notably Galen—relied heavily on the dissection and vivisection of animals, such as pigs, goats, and Barbary apes, to infer human structure and function. While this approach allowed for some medical advancements, it also led to significant anatomical errors, as animal physiology does not always accurately reflect human biology.12

Ethically, it is important to recognize that the human body has historically been treated with a sanctity that prioritizes the dignity of the deceased. The eventual shift toward accepting human dissection was a complex process that required balancing the profound moral weight of these traditions against the scientific necessity of understanding human anatomy to improve medical care and surgical practice.34
