The origins of liturgical music traditionally date back to St. Gregory the Great (d. 604), who was inspired by the Holy Dove to record the principles of 'Gregorian' chant. The Gradual contained the musical parts of the Missal and was sung from the steps (gradus) of the altar. The Antiphoner contained the musical sections of the Breviary. These terms have become interchangeable in modern times. Because of their size and complexity, these manuscripts were still being handmade in the traditional way for centuries after the introduction of printing. They were boldly hand-written and illuminated on large sheets of sturdy vellum so that the entire choir could read from one book.

This impressive elephant folio sheet contains five-line music in red and black ink with one large initial. The song translates as:

May all flesh bless his holy name.
All the nations, which you have made, will draw near and adore in your presence, O Lord.
And they will glorify your name.
For you are great, and you perform wonders.
You alone are God.
