Gerhoh compiled the
Annales Reicherspergenses (Annals of Reichersberg), which cover the years 921–1167. His pupil,
Magnus of Reichersberg, continued them down to 1195 and later writers added material down to 1279. His reformist views and his ecclesiastical policy are set forth in the following works: •
De ædificio Dei seu de studio et cura disciplinæ ecclesiasticæ (
P.L., CXCIV, 1187–1336;
Ernst Sackur, 136-202) •
Tractatus adversus Simoniacos (
P.L., 1335–1372; Sackur, 239–272; see also Jaksch in
Mittheilungen des Instituts für österreichische Geschichtsforschung, VI [1885], 254-69) •
Liber epistolaris ad Innocentium II. Pont. Max. de eo quis distet inter clericos sæculares et regulares (
P.L., CXCIV, 1375–1420; Sackur, 202-239) •
De novitatibus hujus sæculi ad Adrianum IV Papam (selections in Grisar and in Sackur, 288-304). • the important work written in 1162,
De investigatione Anti-Christi libri III [selections in
P.L., CXCIV, 1443–1480; see also Stülz in
Archiv für österreichische Geschichte, XXII (1858), 127–188; selections in Scheibelberger, see below; book I complete in Sackur, 304-395] •
De schismate ad cardinales [Mühlbacher in
Archiv für österreichische Geschichte, XLVII (1871), 355–382; Sackur, 399-411] • his last work is the
De quarta vigilia noctis [
Oesterreichische Vierteljahresschrift für kath. Theologie X (1871), 565–606; Sackur, 503-525]. His principal work was
Commentarius in Psalmos (
P.L., CXCIII, 619–1814; CXCIV, 1-1066). Despite its unfinished state, it contains various material of historical interest. This is particularly true of his commentary on Ps. lxiv, that appeared separately as
Liber de corrupto Ecclesiæ statu ad Eugenium III Papam (
P.L., CXCIV, 9-120); Sackur, 439-92). There are also a number of polemical works and letters against the
Christological views of
Abelard,
Gilbert de la Porrée, and Bishop
Eberhard of Bamberg; others deal with the errors of Folmar, Provost of
Triefenstein, on the subject of the
Holy Eucharist. The genuineness of the
Vitæ beatorum abbatum Formbacensium Berengeri et Wirntonis, O.S.B., generally ascribed to Gerhoh, is denied by
Wattenbach. The Migne edition of Gerhoh's works is faulty and incomplete. Those of his writings which are of importance for the study of the history of that period were edited by Sackur in the
Monumenta Germaniæ Historica: Libelli de lite imperatorum et pontificum, III (Hanover, 1897), 131–525; also by
Scheibelberger,
Gerhohi Opera adhuc inedita (Linz, 1875). ==References==
