Luc d'Achery

Luc d'Achery (1609 – 29 April 1685) was a learned French Benedictine of the Congregation of St. Maur, a specialist in the study and publication of medieval manuscripts.

He entered the Order of St. Benedict at an early age and was professed at the Trinity Abbey, Vendôme, on 4 October 1632, but his health soon obliged him to remove to Paris.

By a continuous correspondence with other monasteries, both in and out of France, he made himself a bibliographical authority of the first rank, especially in all that pertained to the unedited or forgotten writings of medieval scholars.

His first important work was an edition (Paris, 1645) of the Epistle of Barnabas, whose Greek text had been prepared for the press, before his death, by the Maurist Hugo Menardus.

D'Achery collected the historical materials for the "Acta Ordinis S. Benedicti" but Mabillon added so much to it in the way of prefaces, notes, and "excursus" that it is justly accounted as his work.
