CABASSUT, Jean. — Oratorian, born in Aix-en-Provence in 1605, died there on 25 September 1685. He entered the Congregation of the Oratory in 1626. Initially devoting himself to the study of Oriental languages, he later abandoned them to turn to Canon Law. Cardinal Grimaldi, Archbishop of Aix, often made use of his counsel and held him in such high regard that in 1660 he wished him to accompany him to Rome for the Conclave in which Alexander VII was elected. On that occasion, he remained in Rome for eighteen months, deepening his study of the sources of law.
He wrote: *Notitia Conciliorum Sanctae Ecclesiae*... Lyon 1668, completely reworked by the same author in 1680 under the title: *Notitia Ecclesiastica historiarum Conciliorum et Canonum*..., an orderly exposition of councils and canons from the earliest times of the Church; *Theoria et Praxis Iuris Canonici*, Lyon 1660, a work notable for its practical character and sound doctrine, avoiding the excesses of rigorism and laxism; *De Usura*, at the invitation of Cardinal Grimaldi.
