Reading Anund & Qviberg’s new guide book on Medieval Uppland, I came across a great religious legend: “The Grateful Dead“. (The band got its name from a dictionary entry on this family of stories.) The earliest version of the legend is found in the German Cistercian prior Caesarius of Heisterbach’s 13th century book of miracle stories, the Dialogus miraculorum. This book was hugely popular for centuries, and though Caesarius is largely forgotten today, we do remember his chilling line about how to tell a Cathar from a Catholic, attributed by Caesarius to one of the Albigensian Crusade’s leaders: “Kill them all and let God sort them out”.
The cool thing about “The Grateful Dead” is that the story has zombies. Caesarius tells us:
There was a once a man who had the habit, when he passed a churchyard, always to stop and pray for the souls of the dead whose bodies were buried there. Once it occurred that he was pursued by armed enemies into this churchyard, and lo! all the graves in the churchyard opened and one saw all the dead bodies, armed with swords and staffs, hasten to the man’s aid. For fear of them, the terrified enemies turned back and ceased to pursue the man.
In the 15th century, this legend was a popular subject of church art across German-speaking Northern Europe. At least four churches in the Swedish province of Uppland has murals of the Grateful Dead: Biskopskulla, Roslagsbro, Rö and Yttergran. The story was lent new relevance by the Late Medieval preoccupation with Purgatory, where much of religious life became concentrated on ways to shorten the period of cleansing torture — such as indulgences. In that era’s interpretation of the legend, the dead rise to save a man who makes a habit of praying for their souls, thus shortening their stay in Purgatory.
And the imagery lives on. In early fantasy games of the Dungeons & Dragons ilk there was a trope about zombies wielding agricultural implements as weapons. I bet this came straight from Medieval art. The image below is from Jackson & Livingstone’s bestselling 1982 choose-your-own-adventure book The Warlock of Firetop Mountain.
I’ve found two good papers on the Grateful Dead in Medieval art available on-line, by Hans Wieser 1947 in German and by Åke Nisbeth 1953 in Swedish.
