The Afterlife of Petrarch’s Liber sine nomine in Catholic and Protestant Contexts: The Case of Bernhard von Kraiburg’s Epistle on the Fall of Constantinople (1453)

Petrarch’s Liber sine nomine is a collection of satirical letters against the Avignon Curia, remarkable for its stylistic refinement. It offered later readers multiple possibilities of interpretation and reuse, serving both as a rhetorical model and as a resource for anti-papal argumentation. While literary application predominated in the fifteenth century, the collection was later repurposed in religious debates between Protestants and Catholics. This paper examines a little-known episode in its afterlife, namely the epistle on the fall of Constantinople in 1453 by Bernhard von Kraiburg, chancellor of the Archbishop of Salzburg and later Bishop of Chiemsee. Close philological analysis shows that Bernhard adapted extensive passages from the Liber sine nomine and, along with a few other authors, established a distinct line of reception by reinterpreting selected letters as prayers. In the second half of the seventeenth century, however, Bernhard’s work met an analogous fate to that of its model. It was read and reframed from a Lutheran perspective by Johann Konrad Dieterich, professor of Greek and history at the University of Gießen, and was subsequently subjected to indirect censorship in the Index librorum prohibitorum.
