LXXX, indictione VIII, regni Lotharii regis XXV anno, dedit idem rex Brunoni Remensis Ecclesie clerico, suo parenti propinquitate consanguinitatis existenti, Episcopatum Lingonice civitatis. Ordinatus est autem Bruno Episcopus per manus Burchardi Lugdunensis Archiepiscopi in ecclesia sancti Stephani, viginti quatuor gerens annos etatis: et eodem anno susceptus est a clero Lingonice urbis, ab Incarnatione videlicet Christi DCCCC. LXXXI." Chron. S.-Bénigne, 128-9].
