The oldest existing forensic science text is The Washing Away of Wrongs (also known as the Collected Cases of Injustice Rectified, or Hsi yuan chi lu), written around 1247 CE. Sung Tz’u (or Song Ci), who is considered to be the “Founding Father of Forensic Science in China,” wrote this text to help bureaucrats of the Southern Sung Dynasty navigate the complex inquest process, provide instructions on how examine a corpse, and determine cause of death.  This forensic manual predates the earliest European texts on the subject by hundreds of years.

By the time The Washing Away of Wrongs was written in the mid-thirteenth century China had already been conducting forensic assessments for violent or suspicious deaths for centuries. Going as far back to at least the Ch’in Dynasty (221-207 BCE), the Chinese government ordered forensic investigations in hanging deaths (Sung 1247/1981, p. 4). Then in 995 CE, a decree was issued establishing an inquest system for homicides, unusual deaths, and serious injuries.

Bureaucrats, not full-time detectives or forensic scientists, were responsible for leading inquests as a small part of their duties (Sung 1247/1981, p. 5).  Professionals, who were the equivalent of coroners or midwives, were asked to examine a corpse during an inquest (Sung 1247/1981, p. 11).   According to McKnight’s translation (1981), there was an institutional distrust of coroners and midwives because they were not government officials (Sung 1247/1981, p. 18).  So bureaucrats were tasked with confirming the findings of a coroner during an autopsy (Sung 1247/1981, p. 21). To do this, they had to be able to indicate the specific wound responsible for death, differentiate between accidental and deliberate deaths, and distinguish between peri-mortem and post-mortem wounds (Sung 1247/1981, p. 21).

The Washing Away of Wrongs was written as step-by-step guide to avoid errors during this process because Sung Tz’u believed it was important to prevent the miscarriage of justice (Sung 1247/1981, p. 38). He compiled “materials from various authors, corrected them, and added his own observations (Sung 1247/1981, p. 39).

The parts of this text where Sung Tz’u discusses proper inquest procedure and documentation are pretty boring. But the sections about the human skeleton, decomposition, and case studies are really interesting because they illustrate the use of forensic anthropology in a medieval context.

In the below excerpts from Brian McKnight’s 1981 translation of The Washing Away of Wrongs, Sung Tz’u describes how medieval investigators tried to use forensic anthropological techniques to differentiate between male and female bodies, time since death, and cause of death. Although there are many inaccuracies, it’s fascinating to read how these methods were starting to be developed and applied in different cases.

Examination of Bones (1.82a/71-1.82b/71)

Man has three hundred sixty-five bones, corresponding to the three hundred sixty-five days in a year.

The bones of men are whitish. Those of females are darker. (When women give birth, their bones produce blood like a flow of water. Therefore, the bones will be darkish. If someone swallows poison, the bones will also be darkish. This must be examined very carefully before deciding [whether the bones should be adjudged light or dark].)

Skulls: in a male, there are a total of eight plates, counting from the nape of the neck to the ears, together with the plates of the back of the skull. There is a horizontal suture across the back of the skull and a vertical one running down to the hairline in the back. In women, there are only six plates. There are only six plates. There is a horizontal suture across the back of the skull, but no vertical suture.

…The pelvic bone resembles the kidneys of a pig, with the indented part under the spine. In males, at the place where this bone meets the spinal column it is concave. On each side, there are little pointed stems like the upturned angular ends of palace roofs. It has nine holes. (p.95-97)

Decay of Corpses in the Four Seasons (1.37a/68-1.32b/69)

During the three months of spring, when a body is two or three days old, the flesh of the mouth, nose, belly, ribs, and chest becomes slightly livid. After ten days, a foul liquid issues from the nose and ears…

During the three months of summer, when the body is one or two days old, the flesh will change color, beginning with the face, belly, ribs, and chest. When three days have passed, a foul liquid will issue from the mouth and nose, and maggots will appear. The whole body will swell, the lips will pull back, the skin will rot and separate from the flesh, and blisters will appear. After four or five days, the hair falls out…

During the three months of autumn, after two or three days have passed, a body will be first as described above for the spring, with the flesh of the face, belly, ribs, and chest changed in color. After four or five days, a foul liquid will issue from the mouth and nose, the whole body will swell, the lips will curl back, and blisters will appear. After six or seven days, the hair will out.

During the three winter months, when four or five days have passed, the flesh of the corpse will turn yellowish purple. After half a month, the symptoms described above will appear first, with the face, mouth, nose, sides, and chest all changing color. Sometimes, if the place is damp, and the corpse is wrapped in mats and buried, this will slow the process of decay. Again, consider carefully whether it is the beginning or end of the month, and determine your actions according to the seasons of spring or autumn.

When it is extremely hot, decomposition of the corpse begins even after a single day. It becomes livid or blackish and begins to smell. After three or four days the skin and flesh become rotten, the corpse swells, maggots appear, there is a discharge from the mouth and nose, and the hair falls out.

In extremely cold weather, five days is equivalent to one day in a time of great heat, and half a month the equivalent of three or four extremely hot days. In spring or fall when the weather is equable, two or three days are equivalent to one day in summer, and eight or nine days are equivalent to three or four summer days. But men maybe fat or thin, old or young. Those who are fat or young decay easily. Those who are thin or old decay more slowly. Also, the climate is not the same in north and south, and in the mountains the coldness and warmth are constant. At such times, even more care than usual must be exercised in investigating all changes. (p. 86-87)

Discussion of Miscellaneous Doubtful and Difficult Cases: Part Two (17)

Formerly, a man was found drowned in a deep pool. He had been there a long time. The affair was made known because of spite. The investigating official saw that the corpse had no skin or flesh left on it. Only the skull and bones remained. A succession of dispatched officials were not willing to hold an inquest. The superior office assigned the responsibility to several men. Only one official was willing to accept it. He then went to the place to examine the bones. First, he very carefully examined what could be seen. There were no other pieces of evidence. He then took the skull and washed it. He took a hot water jug and carefully poured clean hot water into the skull through the fontanel, examining the water to see if any sand or mud came through the nose. He used this to determine whether or not the victim had been alive when he entered the water so had drowned. Generally, when living people fall into the water, sand or dirt will be aspirated into the nose. If the body was put into the water after death, then there will be no sand or mud.

In Kuang-yu, there was an evil rogue who plotted to kill a young boy and seize what he had been carrying on the trip. When the crime was discovered, the day when the murder had been committed was already long and past. The criminal confessed, saying, “I beat him and then threw him in the water.” The office of the Sheriff had already dragged the body from the water. The flesh had rotted away, and there were only bones left, so there could bot be an inquest. In the end, [the investigating official] could not avoid suspecting a coincidence [i.e., that the bones belonged to someone else], so no one dared to make a judgment.   Eventually, someone, in reading over the case records, noted that in the depositions of relatives turned in the original investigating official, one relative had state this his younger brother had been pigeon breasted and undersized. Subsequently, an official was dispatched to conduct a re-inquest. The chest bones were as described. Only then did they dare to pronounce a penalty. (p. 70-71)
