Anecdotes
In 1681, Mabillon published De re diplomatica, a work of more than 500 pages in which he established scientific criteria for authenticating medieval charters. The book put an end to a dispute with the Bollandist Daniel van Papenbroeck, who had challenged the authenticity of Merovingian documents. Mabillon responded with exemplary rigor and courtesy, demonstrating through analysis of the handwriting, parchment, and seals that the charters were indeed authentic.
The Abbé de Rancé, reformer of the Abbey of La Trappe, publicly attacked Mabillon in 1692, arguing that monks should not devote their lives to intellectual study but solely to prayer and manual labor. Mabillon responded with his Traité des études monastiques, defending with moderation and erudition the compatibility between monastic life and scholarly work. This exchange remains one of the most celebrated debates in seventeenth-century Catholicism.
Between 1683 and 1686, Mabillon undertook lengthy journeys to Germany and Italy to consult directly the archives of the great European abbeys and libraries. He visited dozens of monasteries, transcribed thousands of documents, and brought back to Paris previously unknown information about the medieval written heritage. These travels were funded by Colbert, who supported the scholarly work of the Maurists in service of France's intellectual prestige.
At Mabillon's death in 1707, the Abbey of Saint-Germain-des-Prés went into mourning and scholars from across Europe paid tribute to his memory. Voltaire himself — rarely generous toward men of religion — would later acknowledge that Mabillon had founded a true science. His name remains to this day associated with the critical historical method, far beyond monastic circles.
