The debate over the poverty of Christ and his apostles under Pope John XXII (1316-1334) is one of the most famous intellectual controversies of the Middle Ages. The story of the uncompromising pope on collision course with a united Franciscan Order has often been told, most memorably by Umberto Eco in The Name of the Rose. In this book, Patrick Nold sets out to investigate the Franciscan Cardinal Bertrand de la Tour, a man apparently torn between the pope who was his patron and the Order to which he had devoted his life.
