Depiction of the fourth horseman of the apocalypse, Death, riding a mythical creature, presumably a winged lion. Below him is a personification of famine (Fames), pointing to her open mouth. The depiction was created in Erfurt in the mid-14th century; the connection to Neuses may be drawn due to the date – St. Mark’s Day – of the annual memorial procession leading to the mass grave.

Photograph of the fresco Trionfo della Morte, taken at its original location in the Camposanto Monumentale in Pisa. The fresco, known as the “Triumph of Death” and attributed to the painter Buonamico Buffalmacco, is not precisely dated; scholarly estimates range from 1335 to 1350. While it does not depict the Black Death explicitly, the selected detail shows victims of an epidemic from diverse social backgrounds, their souls carried off by demons.

Medieval volcanoes may have ignited the Black Death
