Everything you needed to know about medieval parasites

AEON has a fairly long essay up on the above topic, full of interesting details, some of which I have not heard before.  Like this bit about a perceived Jewish custom:
At the same time, the filthiness of medieval people should not be exaggerated. Much evidence shows that personal hygiene mattered to medieval people, that they made an effort to keep clean. Popular advice books recommended washing the hands, face and teeth on rising, plus further handwashing throughout the day. Other body parts were washed less frequently: daily washing of the genitals, for example, was believed to be a Jewish custom, and thus viewed with suspicion by the non-Jewish population.
Hmm.  I would have thought that having smelly genitals might have given medieval folk a clue that the Jews were onto something there (whether or not they really did it); but no, apparently not.

The article spends a lot of time noting how perceptions that parasites just arose spontaneously out of the body meant that people didn't hold any hope of preventing them:  they had no idea that they are "caught":
Children were thought to be particularly vulnerable to intestinal parasites because they were naturally warm and wet. Mothers were advised not to give under-sevens too many phlegmatic and viscous foods, such as fruit and oily fish. Convention held that these types of food impeded digestion and unbalanced infant humours, leaving them vulnerable to worms. The susceptibility of adults also depended on diet, among other things. According to Bernard of Gordon, professor of medicine at the University of Montpellier from 1285, gluttons were particularly prone to worms. When the barber of Thomas Cantilupe, bishop of Hereford, asked another servant why their master had so many lice, he replied that ‘it happened naturally to some men more than others’.
They would try to remove them, though, with some herbal ideas, and others more dangerous.  (A head lice treatment with mercury in it, for example.   I wonder - is it just the shiny, interesting attractiveness of that element that led people to believe it was good for all that ails us?  It has surely caused a great deal of human suffering over the centuries.)

The final section explains how the one part of society that embraced lice and parasites was the clergy, viewing suffering from them as a sign of ascetic devotion to God:

The most devout Christians not only thought about parasites, but also embraced them as part of their daily lives. Numerous doctors remarked on the clergy’s susceptibility to parasites, including John of Gaddesden, to whom it was clear that the religious were prone to lice because of their lack of grooming. Bernard of Gordon blamed their consumption of phlegmatic and melancholic foods. Medieval literature is scattered with examples of monks and nuns who are troubled by lice. In the 12th-century verse Planctus monialis, a young nun complains about the hardships of her life, and begs a young man to sleep with her. Among her problems were the unhygienic conditions in which she was forced to live: ‘The shift I wear is grim, the underwear unfresh, made of coarse thread … there’s a stench of filth in my delicate hair, and I put up with the lice that scratch my skin.’....

Throughout the middle ages, holy men and women ignored conventional hygiene, and consequently suffered. Laurence of Subiaco, a 13th-century hermit, wore a coat of chainmail that continually ripped his flesh and was ‘full of lice’, while St Margaret of Hungary (a Dominican nun of royal birth) refused to wash her hair so that she would be tormented by lice. The 14th-century Dominican mystic Henry de Suso wore a hairshirt and was often ‘tortured by vermin’; eventually, he took to wearing leather gloves with sharp tacks sticking outwards, so that if he tried to scratch at his bites in his sleep he would claw at his flesh. Even rich and powerful churchmen might embrace this form of suffering, concealing their penitential garments (and the creatures that lived in them) under their splendid vestments. After Thomas Becket was murdered in his cathedral, the monks who prepared his body for burial discovered that he wore hair undergarments, and
This goat hair underwear was swarming, inside and out, with minute fleas and lice, masses of them all over in large patches, so voraciously attacking his flesh that it was nothing short of a miracle that he was able to tolerate such punishment.
The monks interpreted these vermin as a form of martyrdom. During the canonisation inquiry for Thomas Cantilupe, his servants reported that his bedding and clothing were full of lice. One claimed that there were whole handfuls of them. Another said that he had never seen so many lice, either on paupers or on the rich.

I think I had read that about Thomas Becket before (maybe posted about it?), but I didn't know that more generally, the devout held that ignoring lice and other parasites was a good thing to show their holiness.

The 21st century is a pretty good place to be.
