BREVIARIUM (BREVIARIUS). – They mean compendium (like breviculum and breviculus) and were already frequently used in the classical age as titles of books (Augustus had a B. imperii drawn up, and Eutropius wrote a B. historiae romanae); they then recur in the patristic age; cf. St. Augustine’s Breviculus collationis cum Donatistis.
Some of these works, whose authorship is uncertain, are often cited anonymously, and are especially: 1) B. fidei adversus
BREVIARY — Letter F with Christ in glory. R. of Montéramey (12th c.) — Paris, National Library, ms. lat. 796, fol. 235.
