BERENGOZ of TREVRI. — Benedictine abbot of S. Massimino, who rendered meritorious service by reclaiming from Henry V various rights and possessions, died around 1125. He distinguished himself as a man of letters, leaving besides five *Sermons* (panegyrics for the feast of martyrs, confessors, the dedication, and relics) two works: *De laude et inventione sanctae crucis libri 3* and *De mysterio ligni dominici et de luce visibili et invisibili per quam antiqui patres olim meruerunt illustrari* (PL 160, 935-1036). The latter extols Christ as the “true light” from the dawn of humanity, in both the Old and New Testaments; it also elucidates a theme then of great relevance: the harmonious relations between priesthood and empire, made possible in the King-Priest Christ. The former work expounds three figures of the Cross (Joseph, Isaac, Moses), its discovery and efficacy, in the life of St. Helena “Treviarum quondam indigena civitatis” (ibid. 953) and of Constantine.
