The cardinals -- at least, those under 80 years old -- vote for as long as it takes to elect Pope Francis' successor.

Crowds of mourners waited in line on Sunday for a chance to visit Pope Francis’ final resting place in the Santa Maria Maggiore church in Rome, a day after his funeral service that was attended by world leaders and royalty.

Most of the funeral will be celebrated in Latin, and there will be incense and hymns and Gregorian chants. Attended by dozens of heads of state, monarchs and other dignitaries, it will be, in any case, a spectacle. And at the center of it all will be Francis’ simple coffin, on the esplanade of St. Peter’s Basilica.
