Body Worlds

Artistic Expression of Hard Science

by Julie Sculley

Currently on display at the Houston Museum of Natural Science is Gunther von Hagens’ Body Worlds 3: The Anatomical Exhibition of Real Human Bodies. This exhibit is set to run through September 4, and features over 200 specimens of individual organs, organ systems, and entire human bodies, preserved by von Hagens’ ground-breaking preservation technique called plastination.

Artistic expression or hard science? Taking in the often shockingly dramatic exhibits, one is forced to ask this fundamental question. Alternately fascinating and macabre, the journey through Body Worlds overwhelms the viewer with a parade of whole-body plastinations posed to present pictures of human activity both mundane and extreme. One of the most memorable is The Skin Man. This specimen is of a man in full stride, all musculature exposed, with his entire, intact skin draped casually over one up-stretched arm, resembling a full-length overcoat. Other exhibit elements include skin removed fully or partially, muscle layers cut and reflected back to expose organs or skeletal elements underneath, eyeballs set in skeletal sockets, skulls cut away to reveal the preserved brain inside, carefully cut-out lips adding expression to otherwise skinless faces, whole organ systems displayed intact, and entire figures in an “exploded” or pulled-apart view.

Especially fascinating and beautiful are the preserved circulatory systems, appearing as delicate, scarlet, lacework facsimiles of the animal or human body part from which they originated.

Many specimens make plain the cause of death of the individual that they came from. Cancerous kidneys, livers, lungs, breasts, and abdominal cavities encased in thin plastic slices reveal deadly malignant masses. Livers, scarred from years of substance abuse or lumpy with tumors are shown as entire specimens. Likewise, malformed or diseased kidneys line one display case; while in another, enlarged, diseased hearts are opened to expose the valves inside. A thin, plastinated slice taken lengthwise, head to toe, from the body of a morbidly obese man effectively illustrates the inherent repercussions resulting from overeating. Arguably the most poignant displays are those of smoker’s lungs. Sickeningly black with tar, tattered by emphysema or filled with tumors and shown in their entirety or in slices, these grotesque specimens are a singularly effective smoking deterrent.

Other noteworthy exhibits, each with a fairly obvious intent, include a group of gentlemen, all flayed, some with exposed brains, smoker’s lungs, spines, etc., jauntily positioned about a table, smoking and surrounded by drinks while engaged in a card game. One might infer from the selected dissections that a lifestyle of drinking and gambling are not particularly healthy. The most imposing is a magnificent rearing horse, easily 18 hands high, with a rider astride him. Both are flayed, the horse’s magnificent musculature exposed, and the rider is presented in an “exploded” or pulled-apart view. The rider is gazing down at his own brain held in his outstretched right hand, while in his left hand he holds the smaller brain of the horse. Any layperson can easily see the lesson in comparative anatomy in how both horse and man are essentially structured the same, but with vastly different proportions.

Surrounded by controversy due to ethical and moral issues raised by the displays, Body Worlds exhibits have attracted millions of visitors around the world since 1996. Touted as an anatomical display of the human body of scientific significance, many detractors argue that the often-whimsical feel to the exhibits constitutes a lack of respect for the deceased. It is however, the manner of dissection and subsequent presentation of the dissected figures that is a major source of the controversy.

There has also been some speculation that some of van Hagens’ early specimens were the bodies of executed Chinese. While he denies that any exhibits have ever been created from such cadavers, van Hagens does acknowledge that it is possible that some may have been dropped off at a production facility in Northeastern China. It is important to note that Body Worlds expressly denies this claim.

Supporters argue that all the cadavers are the remains of individuals that gave informed consent to be preserved in this manner prior to their deaths. The Institute for Plastination located in Heidelberg, Germany currently has a donor list of over 6500 individuals including 142 Americans. Although positioned “artfully,” the context of the exhibits is scientific, each one presented with a carefully prepared explanation of what anatomical feature is illustrated, and why it has been prepared in the manner shown. Faces have been rendered unrecognizable by way of strategic dissection in order to distinguish each subject as a specimen and not as a corpse.

Artistic presentations of the dead are not without historical precedent. Fanciful anatomical renderings were common during the renaissance era. In fact, a likely image of inspiration for Skin Man comes from Anatomia del corpo humano, a 16th century anatomical volume by the Spanish anatomist Juan Valverde de Amusco and illustrated by Gaspar Becerra. This illustration depicts a skinless man with carefully illustrated musculature, contemplating his own skin held in his upraised right hand, a dagger held in the other.

Also analogous to Body World’s plastinates is the artistic usage of skeletal remains in bone repositories known as ossuaries. An Ossuary in Kutna Hora, Czech, festooned by unimaginable arrangements of bone including a chandelier, a huge coat of arms, columns, and many other architectural adornments fashioned from as many as 40,000 individuals, makes an awe-inspiring spectacle. Another ossuary sporting a less impressive array of bones laid out in various designs made from the remains of about 25,000 dead exists in the catacombs beneath the San Franciscan Monastery in Lima, Peru.

Historically, mankind has sought to preserve the living image of the deceased through the usage of various preservative substances such as honey, wax, alcohol, oils, salts, herbs, and spices. Today, culturally accepted embalming utilizes special chemicals injected into the body’s circulatory system in order to achieve a superficially similar effect. Ancient cultures such as that of the Egyptians, mummified their dead in order to ensure that the deceased would have a body for its rebirth in the afterlife, whereas modern embalming is performed for the sake of presentation at the time of mourning and for sanitary reasons.

In contrast, plastination begins with the carefully planned dissection of the subject. Next, all fluids and soluble fats are extracted, after which the tissues are forcibly impregnated with special polymers using a vacuum system. At this stage, the body is still pliable, and is posed for presentation. To preserve the pose, this step is followed by heat, light or gas curing, which will harden the specimen. The end result is an astonishingly well-preserved body with all tissues retaining their natural color and dimensions.

Von Hagens’ original intent, however was not to perfect the embalming process. He developed plastination to preserve medical specimens for study by medical students in such a manner that they would withstand decomposition indefinitely and be conveniently handled. However, after taking note of the generally positive reaction by the public to these plastinated specimens, von Hagens conceived of the idea to create aesthetically interesting exhibitions that, in his words, would “avoid shocking the public and capture their imagination.”

Taken in its entirety, Body Worlds 3 represents a fantastic voyage through the subjects of anatomy, health, and at its core basic humanity. Presented with an artistic expression that is both aesthetically alluring and at times repulsive, it is inarguably fascinating. A note of caution; however, it would not be advisable to bring younger children, as they would not have the ability to correctly interpret the exhibit’s content. For older children, particularly teenagers, Body Worlds would provide a vastly different educational perspective on human biology than that available in public schools. Given the controversy generated by this exhibit, it is up to each individual to judge its value.
