Liturgical writings by Bern of Reichenau

Henry Parkes presents an edition of a selection of liturgical writings by Bern of Reichenau (Berno Augiensis) (d. 1048). Four are edited as securely attributable: Qualiter Adventus Domini celebrari debeat and De observatione ieiunii quatuor temporum, on the permutations of the Church's calendar; De quibusdam rebus ad missae officium pertinentibus libellus, on various matters relating to the Mass; and De varia Psalmorum atque cantuum modulatione, on the relationship between liturgical texts (chiefly of the Divine Office) and their underlying scriptural sources. A short fifth text, Ratio generalis de initio Adventus Domini, has a contested attribution and is offered in appendix.
