A new and accessible translation of Hariulf's History of St Riquier, this book examines the history of a monastic community from the seventh to the eleventh century. It covers the ascetic life of the founding saint and the development of the community under the Carolingians in the late eighth and ninth centuries. There were setbacks when the house was sacked by the Vikings and the founder's relics were stolen for political ends, but it recovered in the tenth and eleventh centuries and developed the links with both the Norman and English courts that enable Hariulf to make interesting observations about the Norman Conquest of England. Hariulf's description of the monastic site with its three churches and the liturgical arrangements practised there, as well as the relics, treasures, books and endowments of a great monastic foundation, make his history an important source for monastic history.
