On Saint Patrick's Day last week, 2010 Christian Culture Lecturer Thomas Cahill published a lively piece in the New York Times Op-Ed page called "Turning Green with Literacy" about the role of early medieval Irish monks and other copyists in preserving much of the literature of Greco-Roman antiquity. It's a re-cap of the argument he made in How the Irish Saved Civilization, the first volume in his "Hinges of History" series whose last volume he will preview in his Lecture on September 22.
