John Paul was the first non-Italian pope in 455 years. Some cardinals have called for a Latin American pope to reflect the huge number of Catholics in the region. Others have said the papacy should return to an Italian, while there are contenders from elsewhere in Europe, as well as from Nigeria and India.
St. Peter's Square, which was packed during the funeral by 250,000 pilgrims and dignitaries from 138 countries, was quiet a day later under a steady rain. Cafes and souvenir shops along nearby Via della Conciliazione reopened, finally freed of the crush of pilgrims.
"I can't talk to you," said a man hawking religious trinkets, key chains and figurines. "After 10 days without work, every second counts."
The exodus of pilgrims was wrapping up Saturday as visitors carrying backpacks, folded flags and rolled-up sleeping bags headed for train stations and parking lots on the outskirts of the city. Few stayed around to see the sights.
"We have come here only to pray," said Ula Maciejowska, 33, who was heading home to Oswiecim, Poland. "We will come another time to shop."
Rome's Mayor, Walter Veltroni, said Rome's population of 2.6 million doubled over the past week, giving a lower figure than earlier police estimates of 4 million visitors. He said 1.3 million people filed past John Paul's body.
Remarkably, the mayor said not a single incident of purse-snatching or theft was reported from Vatican City, the diminutive state that in 2002 was reported to have the highest crime rate in the world, mostly incidents such as pickpocketing.
He said Rome's main train station and the square at Tor Vergata University, where John Paul held a huge Youth Jubilee in 2000, will be renamed after the late pope.
The Vatican post office said special "vacant see" stamps, valid only until a new pope is named, will go on sale Tuesday. Collectors were expected to snap up the 700,000 stamps, which will be sold at the post offices around St. Peter's Square.
