A censored 16th century anatomy book may provide evidence that taboos slowed the development of knowledge of the female genitals, researchers have said.

The 1559 edition of Thomas Gemini's Compediosa Totius Anatomie Delineatio features a depiction of a semi-dissected female torso, and the book's original owner has cut away a neat triangle of paper on which the vagina would have been drawn.

It will be displayed in an exhibition at St John's College at the University of Cambridge, and curator Shelley Hughes said it may offer clues as to why knowledge of the female anatomy lagged behind that of the human body as a whole.

She said the book's original owner was "disturbed by its depiction of a semi-dissected female torso".

"We know this because the offending part, a neat triangle of paper on which the vagina would have been drawn, has been carefully cut away."

She continued: "Sin and female flesh were held in close association in 16th century society with naked women often portrayed as the servants of Satan.

"Perhaps Christian Europe would have to overcome its shame over the female reproductive organs in order to discover more about their structure."

Before the 16th century, many European academics believed that female genital organs were simply lesser versions of male organs, turned inside out.

This dated back to classical medical authorities such as Galen in the 2nd century, who had been prohibited by law in Ancient Rome from cutting up human corpses.

The 16th century was a time of medical revolution, with pioneering researchers such as Andreas Vesalius challenging accepted views on anatomy, with evidence gathered from human dissections and direct observation experiment.

But there was still a reluctance to take on some foundational beliefs in science.

The display shows how an evidence-based knowledge of the structure of the body emerged as superstitious and religious barriers weakened.

The exhibition, to be displayed on Saturday, is called Under The Knife At St John's: A Medical History Of Disease And Dissection.
