A seagull glides past the chimney on the roof of the Sistine Chapel, in St. Peter's Square at the Vatican, Tuesday, March 12, 2013. The most gazed-at item at the Vatican this week will be a humble, copper, 2-meter (6-foot) high chimney that will pipe-out puffs of smoke to tell the world if there's a new pope. Black smoke means "not yet." White smoke means "pope elected." (AP Photo/Dmitry Lovetsky)
A giant monitor in St. Peter's Square at the Vatican, Tuesday, March 12, 2013, shows the heavy wooden door to the Sistine Chapel being closed and locked, signaling the start of the conclave to elect a new pope to succeed Benedict XVI following his stunning resignation. Monsignor Guido Marini, master of liturgical ceremonies, closed the double doors after shouting "Extra omnes," Latin for "all out," telling everyone but those taking part in the conclave to leave the frescoed hall. He then locked it. (AP Photo/Gregorio Borgia)
