Boethius, a late Roman philosopher, composed his last work, De Consolatione Philosophiae, while in prison. His final effort crowned a lifetime of philosophical achievement, and the work was influential throughout the Middle Ages. Frequently translated, the Consolation was one of the books which was chosen by Alfred, a ninth century Anglo-Saxon king, for use in the rebuilding of his kingdom after the Danish invasions. Although intended for an audience which was heavily influenced by a lively pagan tradition, the book was re-interpreted during the Carolingian period to conform to a strict Christian standard. Alfred's own interpretation is indicative of this amalgamation of ancient learning in the milieu of an emerging European culture, as well as his own pragmatic personality.
