In 1957 Ernst Kantorowicz published a book that would be the guide for generations of scholars through the arcane mysteries of medieval political theology. In The King's Two Bodies, Kantorowicz traces the historical problem posed by the "King's two bodies"--the body politic and the body natural--back to the Middle Ages and demonstrates, by placing the concept in its proper setting of medieval thought and political theory, how the early-modern Western monarchies gradually began to develop a "political theology."
