Louis IX, king of France from 1226 to 1270 and twice crusader, was canonized in 1297. He was the last king canonized during the medieval period, and was both one of the most important saints and one of the most important kings of the later Middle Ages. In Blessed Louis, the Most Glorious of Kings: Texts Relating to the Cult of Saint Louis of France, M. Cecilia Gaposchkin presents six previously untranslated texts that informed medieval views of St. Louis IX: two little-known but early and important vitae of Saint Louis; two unedited sermons by the Parisian preacher Jacob of Lausanne (d. 1322); and a liturgical office and proper mass in his honor--the most commonly used liturgical texts composed for Louis' feast day--which were widely copied, read, and disseminated in the Middle Ages.

Gaposchkin's aim is to present to a diverse readership the Louis as he was known and experienced in the Middle Ages: a saint celebrated by the faithful for his virtue and his deeds. She offers for the first time to English readers a typical hagiographical view of Saint Louis, one in counterbalance to that set forth in Jean of Joinville's Life of Saint Louis. Although Joinville's Life has dominated our views of Louis, Joinville's famous account was virtually unknown beyond the French royal court in the Middle Ages and was not printed until the sixteenth century. His portrayal of Louis as an individual and deeply charismatic personality is remarkable, but it is fundamentally unrepresentative of the medieval understanding of Louis. The texts that Gaposchkin translates give immediate access to the reasons why medieval Christians took Louis to be a saint; the texts, and the image of Saint Louis presented in them, she argues, must be understood within the context of the developing history of sanctity and sainthood at the end of the Middle Ages.
