Every year, three thousand people gather in Kalamazoo for the sake of the years 400 to 1400 (approximately) of the Common Era. They come from all over the world to participate in panels like “Attack and Counterattack: The Embattled Frontiers of Medieval Iberia,” “Waste Studies: Excrement in the Middle Ages,” “Historical, Ethnical and Religious Roots of the Thraco-Geto-Dacians and Their Successors: Romanians and Vlaho-Romanians” and “J. K. Rowling’s Medievalism (I & II).” They are literary critics, historians, experts in numismatics and linguistic datasets, and nuns. There are over five hundred sessions: meetings and drinks parties and bookstalls; groups of monks dressed in black; bespectacled, serious, young men; elderly ladies in capped sleeves. Here is a ragtag bunch of human beings all on the same pilgrimage, playing a part in a story that they can’t read, because they’re in it.
