What happened
In 1979, Carlo Ginzburg formally requested Pope John Paul II open the Inquisition Archives. The Vatican opened them in 1998. Ginzburg had earlier used Friulian Inquisition records to reconstruct the benandanti and Menocchio.
How we know it
The document states Ginzburg founded microhistory, published on the benandanti (1966) and Menocchio (1976), formally requested archive access in 1979, and that Cardinal Ratzinger credited that letter as instrumental in the Vatican’s decision. His methodological views—on testimony-material correlation, statistical scepticism, and judicial analogy—are directly quoted or attributed.
Why it went that way
Ginzburg combined archival rigour with conceptual innovation: he treated marginal testimonies not as noise but as recoverable belief systems, correlated them with material traces, and leveraged his academic authority to make a formal, public appeal grounded in historical practice—not ideology.
What is still contested
Whether microhistory generalises beyond the local; whether Ginzburg’s reading of benandanti as pre-Christian fertility cultists holds against later scholarship; and whether his judicial analogy overstates the historian’s capacity to deduce ‘what really happened’ from fragmented testimony.
What it changed
Ginzburg’s work established microhistory as a subdiscipline, shifted attention to non-elite worldviews in early modern Europe, and directly enabled scholarly access to the Inquisition Archives—previously sealed.
Is it worth your time
Yes. Ginzburg reshaped how historians treat fragmentary, marginal evidence—and forced institutional access to a closed archive. His methods remain contested, teachable, and operative in current debates about evidence and voice.
