The Italian priest who uncovered the earliest list of New Testament books

In short: Lodovico Antonio Muratori was a prolific 18th-century scholar and librarian whose tireless archival research reshaped our understanding of Italian history and Christian origins. Beyond his massive historical compilations, he navigated complex religious controversies, advocating for moderation in thought while maintaining his standing within the highest circles of the Church.

Born in 1672 to a modest family in Vignola, Muratori was ordained as a priest in 1694. His career began in earnest at Milan's Ambrosian Library, where he developed a lifelong obsession with unearthing and publishing unedited ancient manuscripts. This work culminated in monumental collections, most notably the twenty-eight-volume Rerum italicarum Scriptores, which documented Italian history from 500 to 1500. His archival rigor was so profound that he discovered the Muratorian fragment—the oldest known list of New Testament books—while compiling his six-volume study on medieval Italian antiquities.

Muratori’s intellectual reach extended far beyond history. He was a polymath who wrote extensively on philosophy, literature, and law, often challenging the status quo. In works like De ingeniorum moderatione in religionis negotio, he explored the boundaries of religious freedom and the moderation of reason. These views frequently drew sharp criticism from contemporaries, particularly regarding his stances on the Immaculate Conception and the veneration of saints. Despite these public disputes, he remained a respected figure, maintaining correspondence with high-ranking officials, including Pope Benedict XIV.

His influence persisted long after his death in 1750. His vast body of work, ranging from his twelve-volume Annali d'Italia to his treatises on Christian charity and public happiness, provided a foundational framework for Italian historical and cultural studies. By the 20th century, his legacy was cemented through new editions of his writings and even a commemorative postage stamp issued by Italy in 1950. Muratori remains a testament to the power of the scholar-archivist, whose dedication to primary sources can alter the historical record for centuries to come.
