Mediaeval doctors could not help the victims of the plague. In fact many were so scared that they would not treat patients© by author suffering from it, and ESCMIDthey often fled. Online Lecture Library Until well into© theby lateauthor Middle Ages, no European physicians were bound by oath to any code of ethics, and the fact that many of ESCMIDthem viewed Online their professionLecture Librarymainly as a lucrative source of income is borne out by the parodies of the doctor figure in numerous novellas.

In his Consilium, Gentile da Foligno advised people to keep blazing fires burning in the rooms of their homes. Gentile also established that all food should be steeped in wine. Acid foods were © by author considered optimal (“There can be no doubt thatESCMID everything thatOnline has Lecture Library been acidified will combat putrefaction”). A plague-preventive diet

The choice of food was strictly disciplined: • Meat was regarded as fairly safe, while fish was dangerous. • Milk needed to be avoided because of its innate corruptibility. • Bread had to be well baked and yeasted to avoid fermentation in the stomach. © by author • Wine and beer were expressly advised, as was dried fruit, whereasESCMID fresh fruit –Online easily Lecture Library perishable – had to be avoided. All food had to be seasoned with highly aromatic substances, and vinegar was the basis of a plague-preventing diet. A few precautions…

In his Florentine Chronicle, Marchionne di Coppo Stefani reports: No doctors were to be found, because they were dying like everybody else; those who could be found wanted exorbitant fees cash-in- hand before entering the house, and having entered, they took the patient's pulse with their heads turned away, and assayed the urine samples from afar, with aromatic herbs held© to by their author noses. A professor at , France’s first and most important school of medicine, advised his colleagues toESCMID close their patients’ Online eyes Lecture or cover them Library with a cloth so as to avoid contagion through eye-to-eye contact. Protective clothing

Nowadays, plague doctors are invariably imagined as wearing hoods/masks with sweet-smelling herbs in the long 'beak', and© by also author covering themselves headESCMID to foot inOnline robes. Lecture Library In actual fact, in the fourteenth century the treatises on the Black Death only advised people to wear clothing that did not retain the miasmas of infection.

The death rate in the Church was particularly high. Priests visited the sick to comfort them, so were likely to catch the plague.

It is difficult to know exactly how many died. Nowadays every death has to© be by registered. author There were no such registers in the Middle Ages.

• The treatise of Giovanni Dondi extensively deals with ‘how to live in the plague time’, and it includes all sorts of measures stemming from the belief that plague is a result of air corruption. • People had to flee from any eastern or southern wind, never expose themselves to the sun, nor settle in either hot or damp localities. • The air had to be purified© by by author burning all manner of incense: juniper, laurel, pine, beech, lemon leaves, rosemary, camphor, sulphur and others. • ESCMIDHandkerchiefs Onlinewere dipped Lecture in aromatic oils,Library to cover the face when going out.

ESCMID Online Lecture Library Controlling health and the masses

Mostly in the early modern Italian city-states, the idea of plague as a contagion© bywent authorfrom strength to strength. The governments took more and more ad hoc measures ESCMIDdesigned to combat Online the spread Lecture of infection. Library These measures often included an element of social control, not necessarily related to the plague itself. The plague in Milan

Milan, which Barnabò Visconti governed more despotically than either the Venetian or the Florentine republics, enforced very strong measures. City officials immediately walled up houses found to have the plague, isolating the© healthy by author in them along with the sick.

In his already-cited Florentine Chronicle, Marchionne di Coppo Stefani reports: When somebody took ill to his bed, the other occupants in panic told him: 'I'm going for the doctor'; and quietly locked the door from the outside and didn't come back. © by author Many were those who begged their families not to abandon them; but when evening came, and ESCMIDwhen the patient Online fell asleep, Lecture the relatives Library went off and did not return. Lorenzo de Monacis

If in Florence and Milan the sick were locked up in their homes and left to die, the chronicler Lorenzo de Monacis portrays a very different, but no less disquieting,© by author picture of what was ESCMIDhappening in Online Venice. Lecture Library The Islands of the Dead

In March 1348, the Grand Council in Venice entrusted three ‘Sages’ with the task of devising an emergency plan “pro conservatione sanitatis”. It was decided to employ porters to go round collecting the dead and dying and taking them to the © by author islands of San Marco in Boccalama or San Leonardo in Fossamala,ESCMID where Online they Lecture Library were then buried in mass graves. It is a spine-chilling thought that “many breathed their last on these boats and many who still had breath in their bodies survived only to yield up their souls in these mass graves”. Members of the family were cynically allowed to accompany the dying, that is to say, to travel © by author voluntarily, despite being healthy, to these islands. ESCMID Online Lecture Library Venice and the Lazzareto

In 1431, a further fundamental© by author institution was created in Venice - the Lazzareto, an Island in the lagoon, where the AugustinianESCMID Monastery Online of Saint Lecture Mary of NazarethLibrary used to stand and where carers of the sick used to come from the lagoon leper hospital dedicated to San Lazzaro.

The psychological trauma originated by the contagion scare was huge. People were used to death in the Middle Ages. Babies often died, people were old at 45, wars were frequent, medicine was often impotent,© and by aauthor poor harvest meant starvation and death. ESCMID Online Lecture Library But the Black Death was far worse.

Fears and violence

Everyone suffered© during by author the plague, but the Jews had to suffer the ferocity of their fellow men, too. ESCMIDLiving in cleaner Online conditions Lecture than their Library neighbours, they were less vulnerable to the plague - which probably gave rise to the belief that they poisoned the wells of the Gentiles. © by author ESCMID Online Lecture Library Pope Clement VI was a collector of Hebrew manuscripts, and his personal physicians were Jewish. His Bull of July 6, 1348, protected the Jews in Avignon and the surrounding area, but could not hope to be© effective by author across the whole of Western ESCMIDEurope. Online Lecture Library Witches

According to popular mediaeval belief, the benevolent ‘white’ witch was capable of curing disease with her potions and knowledge. The persecution of witches was so ferocious, perhaps because they threatened to undermine the authority of the Church and official medicine. It was believed that “whenever© by a author woman attempts to cure the sick without studying, that woman is a witch and should be condemned ESCMIDto death”. Online Lecture Library The Flagellants
