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.
