Cantate Domino is a five-volume commentary on the texts of the newly translated hymns of the Liturgy of the Hours. The hymns which recently appeared for the first time as a single corpus of English texts, will be included in the forthcoming USCCB revised edition of the Liturgy of the Hours. The hymns are drawn from among the very finest authors of the first millennium: Ambrose, Prudentius, and Gregory the Great together with later authors such as Thomas Aquinas, Leo XIII, and twentieth century authors who composed new hymns to be used in the psalter and celebration of the saints in the present Universal Calendar. The commentary concentrates on the Latin texts of the Liturgia Horarum, elucidated by the recently approved International Commission on English in the Liturgy (ICEL) translations. Commentaries have been prepared by a team of international scholars who bring both the depth of their knowledge together with the insights of those who have prepared liturgical texts in English during the sixty years of ICEL's existence. Previously unpublished material from ICEL's archives, including documents of the Consilium, which prepared the Latin texts for the liturgical books promulgated after the Second Vatican Council, will appear alongside commentaries which identify and explain biblical, classical, and liturgical allusions in the liturgical texts in a way that is of service to clergy, religious, liturgists, and students of the liturgy as well as the non-specialist reader, and all who seek to pray the Prayer of the Church with greater understanding.
