ACHERI, LUKE D', a learned Benedictine of the
congregation of St Maur, was born at St Quintin, in
Picardy, in 1609; and made himself famous by print-
ing several works, which till then were only in manu-
script: particularly, the epistle attributed to St Bar-
nabas; the works of Lanfranc, archbishop of Canter-
bury; a collection of scarce and curious pieces, under
the title of Speculegium, i. e. Gleanings, in thirteen vol-
umes, quarto. The prefaces and notes, which he an-
nexed to many of these pieces, show him to have been
a man of genius and abilities. He had also some share in
the pieces inserted in the first volumes of The acts of
the Saints of the order of St Benedict; the title where-
of acquaints us that they were collected and published
by him and Father Mabillon. After a very retired life,
till the age of 73, he died at Paris the 29th of April
1685, in the abbey of St Germain in the Fields, where
he had been librarian.
