Reconciliatione Lapsorum, et de Conciliorum, Decretorum, Decretatium, ipsarumique Pontificum Romanorum Auctoritate (Ingolstiadt, 1612): — Bernoldi Apologeticus pro Gregorio VII, see Tractatuts de Sacramentis Excommunicatorum juxta Assertionem SS. Patrum, in vol. 5 of the Grand Pontifical Library of Jo. Thomas Rocaberti (Rome, 1698): — also some small treatises in favor of Gregory VII, published by the Jesuit Gretser (Ingolstadt, 1609).
