Although the story itself is fiction, many of the persona and events are not. The book is based on research by Monaldi and Sorti, who researched information from 17th-century manuscripts and published works concerning the
siege of Vienna,
the plague and
Atto Melani. In an appendix to the book are listed and examined a number of new historical sources discovered by the authors in the
Vatican Archive and the Public Record Office of Rome – previously unknown to modern historians, and confirming the theory of a secret agreement between William III and Innocent XI. They called upon scholars and professional historians to deepen this research based on the unearthed material.
Historical context The reign of Pope Innocent XI was indeed marked by conflict between the papacy and the French monarchy, in the person of
Louis XIV, over matters such as the French claim to what it called the
Gallican Liberties. For fear of Louis XIV's dominance, not only Innocent but also Catholic leaders such as the king of Spain and the elector of Bavaria supported William of Orange. The conflict between the papacy and Louis XIV continued under Pope Innocent's immediate successors,
Pope Alexander VIII, an ally of William, and
Pope Innocent XII. When news of William's decisive victory over James at the
Battle of the Boyne reached Rome, the papal court, still allied with him against Louis XIV, but by then headed by
Pope Alexander VIII, is reported to have ordered the singing of a
Te Deum of thanksgiving, while similar celebrations were held in Catholic churches in Madrid, Brussels, and Vienna.
Lord Melfort, a strong supporter of King James, reported that the pope "seemed horribly scandalised" that any cathedral had sung a
Te Deum for William's victory; but, as historians observed in 1841, "the plain truth is, that William all along had a strong party among the cardinals ... the great principle of the papal court was to check in Italy the progress of the French, who more than once flattered themselves with the hope of becoming masters of the entire Peninsula. There are reasons for believing that, when the Prince of Orange came over to expel his most Catholic father-in-law, he brought some of the pope's money with him to help him in that undertaking." Professor
Eamonn Duffy, a historian at the University of Cambridge has written, "It is widely accepted, because of James's indebtedness to France, that the Pope was actually relieved when James fell."
Follow-up It has been suggested that the controversial claim damaged the reputation of Pope Innocent and halted
canonisation proceedings. The
Roman Catholic Church had been keen to promote Innocent's cause as an active opponent of the
Ottomans in the light of the terrorist attack by Islamic fundamentalists on
9/11. It was subsequently reported that the authors had been effectively "blackballed by Italian journalism and publishing" because of the embarrassment caused to the church. A spokesman for the Vatican has denied this. Subsequent novels in the series have been published in English -
Secretum in 2009, and
Veritas in 2013. ==References==
