This short work by Hecker is an invaluable medieval history of the Bubonic Plague, known as the Black Death, which ravaged Europe in the late Middle Ages. It's perhaps the best contemporary source, which includes primary accounts about the disease and its effects on victims. All told, when it spread throughout the Mediterranean and Europe, it's believed to have killed anywhere from 30-60% of the entire population.
