The early fourteenth-century Peterborough Psalter was perhaps originally commissioned for a layman, Oliver de Wisset, before being acquired in the 1320s by Hugh de Stukeley, prior of Peterborough Abbey. It is one of the great East Anglian gothic illuminated manuscripts. It opens with a series of spectacular full-page miniatures illustrating scenes in the lives of the Virgin Mary and Christ. The picture here shows the Annunciation, when the angel Gabriel told Mary that she would conceive a son, who would be the saviour of the world. This event was celebrated annually on 25 March, nine months before Christmas.
