Ayear ago our theme was the work of the Bollandists. Their name suggests immediately, to all acquainted with European historiography, the name of another body of religious, many of them the contemporaries of Henskens and Papebroch, and it would be impossible to omit from even the shortest list of great historical enterprises the achievement of the Maurists. The two bodies of men and their work, nevertheless, have little in common save an equal devotion to accurate scholar-ship. What impresses us in the history of Bollandism is its continuity of spirit and undeviating aim over more than three hundred years, during which a very small but perpetually self-renewing group has pursued a single narrowly defined task, which is still far from completion. With the Maurists, on the other hand, it is the magnitude, the variety and the high quality of the achievement that strikes the imagination. While the Bollandists, a small family in a single house, have in three centuries produced in major work no more than a row of sixty-seven folios, the Maurists, in a little more than a hundred years, published matter enough to stock a small library, and left behind them letters, papers and transcripts which have been used and exploited by scholars for nearly two centuries since. Indeed, it would be both impossible and alien to the scope of our interests to attempt the briefest survey of Maurist scholarship in its entirety, and my remarks to-day will be confined to their publications on European history after the decline of the Roman Empire. Who were the Maurists, and wherein lay their peculiar excellence?
