A page from a 'gradual'. 'Graduals' are books of chants for the celebration of the mass. They take their name from the Latin gradus (step), the place near the pulpit where the chants were sung. Commercial music printing in London before 1557 was limited to plainchant hymnals and a very small quantity of secular music for amateurs. It is illuminated in gold and colour by Cristofor Contese.
