CERL Thesaurus is not much help. The date that it gives, 1538– , is simply the date of the first edtion of J.’s De iurisdicione et imperio (TUI 1584 t. 3.1). A man of this name was a theologian and philologian in the 16th century, the editor of a number of large editions of works of the church fathers. We hesitate to identify J. with the philologian, and the Thesaurus may be indicating the same thing by having a separate entry that, so far, lists only the philologian’s edition of St Basil. A clue to an identification may lie in the toponym in J.’s Latin name, Briennensis, which may be Brienne-le-Chateau, dép. Aube.
