In 2012, Steve Green, billionaire and president of the Hobby Lobby chain of craft stores, announced a recent purchase of a Biblical artefact—a fragment of papyrus, just discovered, carrying lines from Paul's letter to the Romans, and dated to the second century CE. Noted scholar Roberta Mazza was stunned. When was this piece discovered, and how could Green acquire such a rare item? The answers, which Mazza spent the next ten years uncovering, came as a shock: the fragment had come from a famous collection held at Oxford University, and its rightful owners had no idea it had been sold.

The letter to the Romans was not the only extraordinary piece in the Green collection. They soon announced newly recovered fragments from the Gospels and writings of Sappho. Mazza's quest to confirm the provenance of these priceless fragments revealed shadowy global networks that make big business of ancient manuscripts, from the Greens' Museum of the Bible and world-famous auction houses like Sotheby's and Christie's, to antique shops in Jerusalem and Istanbul, dealers on eBay, and into the collections of renowned museums and universities.

Mazza's investigation forces us to ask what happens when the supposed custodians of our ancient heritage act in ways that threaten to destroy it. Stolen Fragments illuminates how these recent dealings are not isolated events, but the inevitable result of longstanding colonial practices and the outcome of generations of scholars who have profited from extracting the cultural heritage of places they claim they wish to preserve. Where is the boundary between protection and exploitation, between scholarship and larceny?

Roberta Mazza is Associate Professor of Papyrology at the University of Bologna. She previously held positions at the University of Manchester, where she was honorary curator of the Manchester Museum, and at the University of California, Berkeley.
