The Black Death
A Description of the Plague

This first account is from Messina, and it described the arrival and initial progress of the disease.

At the beginning of October, in the year of the incarnation of the Son of God 1347, twelve Genoese galleys . . . entered the harbor of Messina. In their bones they bore so virulent a disease that anyone who only spoke to them was seized by a mortal illness and in no manner could evade death. The infection spread to everyone who had any contact with the diseased. Those infected felt themselves penetrated by a pain throughout their whole bodies and, so to say, undermined. Then there developed on the thighs or upper arms a boil about the size of a lentil which the people called "burn boil". This infected the whole body, and penetrated it so that the patient violently vomited blood. This vomiting of blood continued without intermission for three days, there being no means of healing it, and then the patient expired.
Not only all those who had speech with them died, but also those who had touched or used any of their things. When the inhabitants of Messina discovered that this sudden death emanated from the Genoese ships they hurriedly ordered them out of the harbor and town. But the evil remained and caused a fearful outbreak of death. Soon men hated each other so much that if a son was attacked by the disease his father would not tend him. If, in spite of all, he dared to approach him, he was immediately infected and was bound to die within three days. Nor was this all; all those dwelling in the same house with him, even the cats and other domestic animals, followed him in death. As the number of deaths increased in Messina many desired to confess their sins to the priests and to draw up their last will and testament. But ecclesiastics, lawyers and notaries refused to enter the houses of the diseased.

Soon the corpses were lying forsaken in the houses. No ecclesiastic, no son, no father and no relation dared to enter, but they hired servants with high wages to bury the dead. The houses of the deceased remained open with all their valuables, gold and jewels. . . . When the catastrophe had reached its climax the Messinians resolved to emigrate. One portion of them settled in the vineyards and fields, but a larger portion sought refuge in the town of Catania. The disease clung to the fugitives and accompanied them everywhere where they turned in search of help. Many of the fleeing fell down by the roadside and dragged themselves into the fields and bushes to expire. Those who reached Catania breathed their last in the hospitals there. The terrified citizens would not permit the burying of fugitives from Messina within the town, and so they were all thrown into deep trenches outside the walls.

Thus the people of Messina dispersed over the whole island of Sicily and with them the disease, so that innumerable people died. The town of Catania lost all its inhabitants, and ultimately sank into complete oblivion. Here not only the "burn blisters" appeared, but there developed gland boils on the groin, the thighs, the arms, or on the neck. At first these were of the size of a hazel nut, and developed accompanied by violent shivering fits, which soon rendered those attacked so weak that they could not stand up, but were forced to lie in their beds consumed by violent fever. Soon the boils grew to the size of a walnut, then to that of a hen's egg or a goose's egg, and they were exceedingly painful, and irritated the body, causing the sufferer to vomit blood. The sickness lasted three days, and on the fourth, at the latest, the patient succumbed. As soon as anyone in Catania was seized with a headache and shivering, he knew that he was bound to pass away within the specified time. . . . When the plague had attained its height in Catania, the patriarch endowed all ecclesiastics, even the youngest, with all priestly powers for the absolution of sin which he himself possessed as bishop and patriarch. But the pestilence raged from October 1347 to April 1348. The patriarch himself was one of the last to be carried off. He died fulfilling his duty. At the same time, Duke Giovanni, who had carefully avoided every infected house and every patient, died.

This account is from Michael Platiensis (1357), quoted in Johannes Nohl, The Black Death, trans. C.H. Clarke (London: George Allen & Unwin Ltd., 1926), pp. 18-20.

Primary sources are written by people actually living through such a situation. Did Michael Platiensis live through it and is he describing what he himself actually saw and experienced?

Yes, this is a primary source. Platiensis was an eye witness.

Yes, this passage can be considered a primary source.

A primary source is a firsthand or contemporary account of an event or topic. It is often written or created by someone who directly experienced or witnessed the event or topic being discussed.

In this case, the passage is a direct account of the Black Death, a description of the plague, written by Michael Platiensis in 1357. This account provides details about the arrival and initial progress of the disease in Messina. As an account written in the 14th century, it qualifies as a primary source because it was created during or close to the time period in which the events took place.
