In this picture released by the Vatican newspaper L'Osservatore Romano, Monsignor Guido Marini, Master of Liturgical Ceremonies, closes the double doors to the Sistine Chapel in after shouting "Extra omnes," Latin for "all out," telling everyone but those taking part in the conclave to leave the frescoed hall, at the Vatican, Tuesday, March 12, 2013. Marini then locked the doors. Cardinals from around the globe locked themselves inside the Sistine Chapel on Tuesday to choose a new leader for the world's 1.2 billion Catholics and their troubled church, surrounded by Michelangelo's imposing frescos imagining the beginning and the end of the world.
