ACHERY, a"ah6"W, JEAN LUC d' (Dom LUC d'Achery; Lat. Dacherius): Benedictine; b. at St. Quentin (80 m. n.e. of Paris), Picardy, 1609; d. in Paris Apr. 29, 1685. He entered the Benedictine order while still very young, and in 1632 joined the congregation of St. Maur at Vend6me. He was of weak constitution and suffered much physically, which led his superiors to send him to Paris. There he became librarian of St. Germain-des-Pr6s, and for forty-five years lived solely for his books and scholarly work. He took especial delight in searching out unknown books and bringing unprinted manuscripts to publication, and was ever ready to help others from his vast store of learning. His chief work was the Spici legaum veterum aliquot seriptorum qui in Gallice bibliotheeis, maxims Benedictinorum, latuerant (13 vols., Paris, 1655-77; 2d ed., by De la Barre, with comparison of later-found manuscripts by Baluze and Marthne, 3 vols., 1723, better arranged but less correct). He edited the first edition of the Epistle of Barnabas (1645), the life and works of Lanfranc (1648), the works of Guibert of Nogent (1651), and the Regula solitariorum of a certain priest Grimlaic (1656); he compiled a catalogue of ascetic writings (1648); and he gathered the material for the Ads. sanctorum ordinis S. Benedicti, which was published by his scholar and assistant, Mabillon (9 vols., 1668-1731), and for which the latter has usually received the credit. (C. PFENDER.)

ACCEMETI, a-sem'e-tai of d"cei-m6'tf,-t6 (" Sleep less"): An order of monks who sang the divine praises in their monasteries night and day without cessation, dividing themselves into three choirs for the purpose and undertaking the service in rotation. A certain Alexander (ASB, Jan., i. 1018-28) founded their first monastery on the Euphrates about the year 400, and a second at Constantinople. The abbot Marcellus spread the custom in the East. Monks from his monastery were transferred in 459 by the consular Studius to the monastery newly founded by him in Con atantinople and called, after his name, the Studium, which later became famous. The members of the order are sometimes called Studites. In the con troversy with the Theopaschites (q.v.) they opposed the views of the papal legate, and in 534 they were disavowed and excommunicated by Pope John II. G. KRBGER.
