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 sheet is from an antiphonary written in four-line music in black and red ink with six large initials. The song translates in part as:

Then did priests make offering of incense and loaves of finest wheat to God, alleluia.
To the victorious I will give hidden manna and a new name, alleluia.
I am the living bread which came down from heaven:
If any man eat of this bread, he shall live for ever, alleluia.
