Book excerpt: Marie-Antoinette, Daughter of the Caesars is about the life, death and legacy of Louis XVI's tragic Queen, based upon the author's thirty years of research. Whenever possible the historical persons speak for themselves out of memoirs and letters. Marie-Antoinette is seen in light of her Imperial heritage as a child of the Habsburg dynasty. Having assumed the crown of the Holy Roman Empire in the 1400's, the crown which had originated with Charlemagne in the year 800, they were seen as the continuation of the Roman Empire of the West. The Habsburgs and their allies kept the Muslims from overrunning Europe at both the Battle of Lepanto in 1571 and at the battle of Vienna in 1683. The fall of Marie-Antoinette, as both Queen of France and the youngest daughter of the Imperial Family, is indicative of the end of Christian civilization and the birth of the secular state, which was the object of the French Revolution. Through her death, Marie-Antoinette has been dubbed "Martyred Queen of Christian Europe" for in killing her the revolutionaries also symbolically killed all that she represented, the ancient heritage of Christendom.
