The indefatigable American Papist, to whom the papal presence is what caffeine is to the rest of us, has a very cool entry on the history of meetings between American presidents and Roman pontiffs, including great photos like this one of JFK & PPVI. He starts with Woodrow Wilson meeting another Pope Benedict, this one B15, at the Vatican on January 4, 1919 and goes up through today’s between between Benedict XVI and Bush.
