a French Jansenist writer, who died in 1775, made himself conspicuous by his opposition to the bull Unigenitus. He is the author of Institution et Instruction Chretiennes (Naples, 1776, 3 volumes), which has often been reprinted, and which contains an exact exposition of the Jansenistic doctrine. To him is also attributed Tractatus de Gratia Christi Salvatoris ac de Praedestinatione Sanctorum, in sex libros distributus (1781, 3 volumes).
