The Saint Louis Psalter (Bibliothque National MS Lat. 10525) is an unusual and intriguing manuscript. Created between 1250 and 1270, it is a prayer book designed for the private devotions of King Louis IX of France and features 78 illustrations of Old Testament scenes set in an ornate architectural setting. Surrounding these elements is a heavy, multicolored border that uses a repeating pattern of a leaf encircled by vines, called a rinceau. When compared to the complete corpus of mid-13th century art, the Saint Louis Psalter's rinceau design has its origin outside the manuscript tradition, from architectural decoration and metalwork and not other manuscripts. This research aims to enhance our understanding of Gothic art and the interrelationship between various media of art and the creation of the complete artistic experience in the High Gothic period
