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.

A small vellum leaf from a Spanish Processional. The pinpricks used to align the text are visible in the margin. One side includes a large initial in red and blue penwork. This sheet is from a Processional, a small book designed to be carried during a procession. To keep these books small often only the first word, or sentence of a hymn was given, as the hymns were all memorized.
