..this is a very interesting and valuable addition to the number of medieval sources now available in English, introducing a selection of underused texts to a new audience of both students and scholars, as well as shedding new light on the memory and afterlife of one of the most famous medieval rulers and best-known saints.- Melanie Brunner (Speculum) The Sanctity of Louis IX aims to reach both scholarly and undergraduate audiences. For students, it offers highly readable and idiomatic translations of texts that have to date only been accessible in nineteenth-century Latin editions.... [T]his excellent set of translations is likely to transform teaching and research on one of the quintessential figues of the European Middle Ages.- Michael Lower (The Catholic Historical Review) Few medieval persons inspire the fascination that the charismatic French king Louis IX (b. 1214) continues to exercise. Inheritor of the crown at age twelve, Louis IX reigned for nearly forty-five years, until his death near Tunis on 25 August 1270. The Sanctity of Louis IX: Early Lives of Saint Louis by Geoffrey of Beaulieu and William of Chartres highlights a dossier of translated texts spanning the almost twenty-seven years between Louis's death and the Bull that canonized him on 11 August 1297.... [T]he book is very likely to prove useful for scholars as well as students. In contrast to the Introduction's very accessible tone, its footnotes direct scholars to a detailed bibliography of specialized works in English, French, and German. Last but not least, an appendix contains a detailed manuscript and publication history of the translated vitae.- Irit Ruth Kleiman (H-France Review)
