In his illustrated book, Klaus Fitschen illuminates the Christian influence on Europe by depicting key processes in the development of religion and the Church, as well as the actions of emperors, popes, martyrs, and heretics. The development from antiquity to the early modern period is presented less as a purely event-driven history and more through the visualization of everyday life, culture, and science across all social strata, as well as through themes such as the Crusades and the Reformation.
