The Book of Psalms contains 150 hymns, which collectively are one of the most important texts in the Abrahamic tradition. They are closely associated with the figure of King David, who was upheld as a model of kingship during the Middle Ages.
So-called Psalters were the most popular type of private devotional manuscript until the emergence of the book of hours. This cornerstone of the Old Testament served as the source material for some of the finest specimens of medieval illumination such as the Bamberg Psalter and Great Canterbury Psalter.
They were primarily commissioned by lay-persons and often doubled as primers for their patrons with miniature cycles covering important Biblical narratives from the Book of Genesis and the Life of Christ in particular.
