Deus omnium

This chant is an antiphon, or musical setting of a psalm, in this case, Psalm 151. It was sung as part of services called the "Summer Histories," or the period after Pentecost (the 7th Sunday after Easter). "The responsories and Lessons for the period after Pentecost draw their texts from Kings, Wisdom, Job, Tobit, Judith, Esther, Ezra and Maccabees. During this time, the lessons and responsories build liturgical sets which are drawn exclusively out of one of these books at a time. These sets of responsories are then referred to by the book from which they come (i.e.;'From Kings,' 'From Judith,' etc.) and are often referred to as the 'summer Histories.'"
