For anyone who has read Robert Darnton’s The Great Cat Massacre, this malady – also called the Polish Plait – promises to satisfy as much strange and macabre fascination for weird history as the backstory of the cat-mutilating printer’s apprentices.

Historically known as the Polish plait, this condition usually results when dirty, neglected, and uncombed hair becomes irreversibly tangled and forms a matted, malodorous, moist stiff mass of hair. Plica Polonica presents typically as an elongated firm to a hard mass of keratin permanently cemented together with crusted pus, blood, nits, and dirt.[1] Plica (or Plicas) may be associated with damage to sections of the cuticle (the hair-shaft’s tough protective outer layer) hereby exposing a moist sticky cortex to which other similarly affected hair shafts adhere. The condition is mildly odiferous and capable of causing adhesion and matting of hair-shafts.[2]

In the early 17th century, people began to believe plaits were an external symptom of an internal illness. A growing plait was supposed to take the illness “out” of the body; the fouler and infested the plait became, the more bad humors were drawn from the body into the hair, and therefore it was rarely cut off. It was believed that purging one’s body of this tangled and stinking pile of hair was extremely risky because it threatened blindness, deafness, confusion of the senses, bleeding, and even death from convulsions.  In addition, the belief that a cut-off plait could avenge itself and bring an even greater illness discouraged some from attacking it, and that casting a magic spell on someone could cause that person to develop a Polish plait.

Initially, what was also called the “tangle” was not associated with lack of personal hygiene. The Polish name kołtun comes from kiełtanie się, i.e. the swinging motion of the tangled hair. It was believed that it arose spontaneously and was a symptom of rheumatism, which was a primary complaint in witches, especially Polish, which is confirmed by the Latin medical name of this ailment – polonica plague, and German – Weichselzopf because it was encountered most often in Poland, along with the banks of the Vistula.[3] Whether contracted by, filth, syphilis, or illness, it was also said that “Jews in taverns are to contribute much to its dissemination by giving vodka after dipping the tangle in it; whoever drinks such a vodka gets a tangle and at the same time becomes a drunk.”[4] The presence of a kołtun supposedly produced “inflammation of the bones, aversion to food, bad eyesight”, and sometimes even “vomiting”.  Few would risk the hazards of cutting off this malodorous bunch of hair that could result in blindness, deafness, insanity, bleeding and even death caused by convulsions.

During the epoch of baroque and the Enlightenment increases in the cases of Polish plait brought about the emergence of competing theses to explain the causes and treatment of the malady, representing a clash of two mentalities, religious and scientific.[5] This misery was considered by many a disease which did not respond to conventional treatments and called for healing by miraculous transformation. Any human attempt to get rid of the tangle was shown as detrimental and causing even more complications such as that suffered by Zofija Mroskowczanka, an unmarried woman. She “cut off a huge Polish plait formed on her head, and for this reason suffered great pain in her bones and eyes, [But] as soon as she devoted herself to a miraculous painting, she was immediately relieved of all her pains.”[6] Even at the beginning of the 19th century, Polish doctors believed that pregnant women had a predisposition to the tangle, and young “tangled” men were released from serving in the tsarist army.

One of the most influential publications of the Age of Enlightenment to include Polish plait in its field of attention was Diderot’s Encyclopaedia. The significance of this insertion called into question the societal belief that Polish plait was a punishment from God, a material manifestation of a disease or evil.  Diderot’s classification eliminated “the secret of a symbol and turned it into an obvious, visible, material object,” separating the manifestation of the disease from sacral symbolism.[7]

Diderot’s classification of Polish plait was also one small entry into “the order and concatenation* of human knowledge,” as was illustrated by the tree of knowledge.[8] By classifying PlicaPolonicaa under the section of pathologies, a subgroup of medicine, under Natural Sciences, Robert Darnton said that the classifications in the Encyclopédie “expressed an attempt to raise a boundary between the known and the unknowable in such a way as to eliminate most of what men held to be sacred from their world of learning.”[9] Whether Diderot or D’Alembert, the author of the entry took a polemic position against any religious manifestation of this disease:

Some authors emphasized even funnier fantastic causes, which were enlarged by fear, spread by deep-seated foolish faith in miracles, and maintained by ignorant credulity. Some common ignoramus, any number of whom can be found in all countries, believed it, and some even more stupid authors wrote about it, although being educated, they should know better than that; according to these authors, Polish plait is caused by magic, magical actions, and can be healed exclusively by supernatural means. According to other authors, the entanglement of hair is brought upon by dead unbaptized infants who perform this work at night. This nonsense was perpetuated by giving it a German name wichteln zoepffe; in Old German wichteln means ‘heathen’, and zoepffe, ‘knot’, ‘entanglement’. Some authors write that only incubi come to suck upon and entangle hair; others argue that incubi appear in the shape of a Jewess, and this popular delusion is registered by the name of juden-zoepffe, etc.[10]

Historian Larry Wolff wrote about plica polonica asan example of eighteenth-century western European prejudice against Eastern Europeans in his book, Inventing Eastern Europe: The Map of Civilization on the Mind of the Enlightenment. Wolff relates the story and attitudes of William Coxe, who had made his Grand Tour, and published his findings in the multi-volume Travels into Poland, Russia, Sweden, and Denmark (1784). Coxe relates this malady with the disease and barbarism of the Polish, linking their illness with backwardness, and critically describing, first, the “Polish air, which is rendered insalubrious by numerous woods and morasses;” second, the water, which the common people chose to drink was “taken indiscriminately from rivers, lakes, and stagnant pools;” and third, “the gross inattention of the natives to cleanliness.”[11]

Plica was already known in pagan times, as indicated by the old name of the disease: wieszczyca, kołtki, skrzot, or skrzat, taken from pagan mythology. From the earliest times, it was believed that the perpetrators of the tangle were evil spirits and demons tormenting vulnerable people. So how did the people get rid of the ‘tangle,’? Piotr Łabędź relates some of the steps taken:

[I]t was necessary to check whether the tangle “wants to collapse”. For this purpose, one had to cut a strand of hair from the four sides of the head and wear them in a bag on the “heart hole”. If, after some time, the hair curled up, it indicated that you need to grow a tangled hair. For this purpose, it was necessary to pour the hair with the herbal decoction of borsch, Giant wall, periwinkle or burdock and rub it with wax from the paschal candle. The safest, however, as the tangled was the devil’s work, was to get rid of him in holy places, such as Częstochowa, Kalwaria Zebrzydowska or, finally, the St. Mary’s Church, famous for this type of “healing.” To remove the tangle, the following words had to be uttered three times: “Saint Benonie, go away with the tangle.” It was then possible to cut the tangle with scissors, symbolically placing it under the church. [Or] you could eat a boiled hedgehog……[12]

At the beginning of the nineteenth century there were doctors who treated tangled as an infectious disease much like leprosy, and even suggested to establish hospitals so that the sick would be separated from the rest of society. Fortunately, there were some brave medical doctors that did not fear to tackle the kołtun. William Dawson (c. 1593-1669), Scottish physician, chemist, botanist, and court musician of Jan Kazimierz Vasa and his wife, Ludwika Maria Gonzaga, proved extremely progressive for the times, by fearlessly cutting kołtuns off and advising combing and frequent washing of the hair. Professor Józef Dietl (1804-1878), rector of the Jagiellonian University, and known today in the practice of urology for discovering and describing the crisis attributable to a kink in the renal vessels or ureter when the kidney dropped as a “Dietl’s crisis,” finally put an end to the kołtun in 1862 by proving its origin and the lack of any connections between cutting it off and illnesses.[13]

Today we see many hair styles that mimic the kołtun, but never fear, they are not infectious, possessed, or a curse; they simply beg to be cut off.
