Tuesday (9/11/2018) marks the 17th anniversary of the cataclysmic jihad terror attacks in the United States on September 11, 2001. Thirteen centuries ago, August 15, 718, under the wise and stalwart leadership of Byzantium’s Leo III, the Arab Muslim jihad siege of Constantinople was broken, and the invaders—and Islamdom—suffered an ignominious defeat. These events are described with unique lucidity, and unbowdlerized knowledge of their animating Islamic, and Christian motivations, in Raymond Ibrahim’s compelling new book, Sword and Scimitar. Would that today’s U.S. and other “Western” leaders re-consider their largely feckless policies against the resurgent jihad depredations of our era (~34,000 acts of jihad terror since 9/11/2001), and re-examine Leo III’s timeless words, and actions.
Leo III’s alleged eighth-century reply letter to the contemporary Muslim Caliph Umar II, who had invited the Byzantine Emperor to renounce Christianity, and adopt Islam, was preserved by the eighth (to tenth?) century Armenian chronicler, Ghevond. Ibrahim’s Sword and Scimitar re-introduced me to both Leo III’s letter, and the great linguist and Islamologist Arthur Jeffrey’s (d. 1959) annotated 1944 English translation, and analysis of Ghevond’s rendering of it, which was succinctly characterized in my 2005 compendium on jihad:
Leo’s reply is an extensive and well-written defense of the major tenets of the Christian religion. In it the Byzantine emperor, who was as zealous in his Christian faith as Umar was in his, refuted Islam on the basis of the Christian Gospel, as well as the basis of the Koran.
Together, Jeffrey’s translation, with its guiding commentary, and Ibrahim’s equally learned, but broader, historical analysis in Sword and Scimitar, make plain that Leo III thoroughly understood, Islam, and its core jihadist doctrine, in both theory and practice.
