Heraldo de Madrid - All eyes turn to conclave as Pope Francis tomb opens to public

Mourners were permitted to visit his tomb for the first time Sunday, a day after an estimated 400,000 people including world leaders turned out for the Argentine's funeral at the Vatican and burial in Rome.

The crowds were a testament to the popularity of Francis, an energetic reformer who championed the poorest and most vulnerable.

Many of those mourning the late pope, who died on Monday aged 88, expressed anxiety about who would succeed him.

"He ended up transforming the Church into something more normal, more human," said Romina Cacciatore, 48, an Argentinian translator living in Italy.

"I'm worried about what's coming."

On Monday morning, cardinals will hold their fifth general meeting since the pope's death, at which they are expected to pick a date for the conclave.

Cardinal-electors at the secret vote will cast four votes per day until one candidate secures a two-thirds majority, a result broadcast to the waiting world by burning papers that emit white smoke.

Luxembourg Cardinal Jean-Claude Hollerich said last week he expected the conclave to take place on May 5 or 6 -- shortly after the nine days of papal mourning, which ends on May 4.

German Cardinal Reinhard Marx told reporters on Saturday the conclave would last just "a few days".

- 'Very emotional' -

Francis's funeral was held in St Peter's Square in bright spring sunshine, a mix of solemn ceremony and an outpouring of emotion for the Church's first Latin American pope.

More crowds gathered on Sunday to view his simple marble tomb at the basilica of Santa Maria Maggiore, his favourite church in Rome.

Francis was buried in an alcove of the church, becoming the first pope in more than a century to be interred outside the Vatican.

"It was very emotional" to see his tomb, said 49-year-old Peruvian Tatiana Alva, who wiped away tears after joining hundreds of others filing past the burial place.

"He was very kind, humble. He used language young people could understand. I don't think the next pope can be the same but I hope he will have an open mind and be realistic about the challenges in the world right now."

A couple of hours after opening, the large basilica was heaving, the crowds periodically shushed over speakers.

Among the mourners were pilgrims and Catholic youth groups who had planned to attend the Sunday canonisation of Carlo Acutis, which was postponed after Francis died.

Friday to Sunday was also the Jubilee of Adolescents, one of a series of events drawing millions to Rome to celebrate the Catholic Holy year.

Raphael De Mas Latrie, 45, from France, said he and his nine-year-old son had "really appreciated" Francis's defence of the environment in particular.

"Today in this material world his message made a lot of sense, particularly to young people," he said.

He added that Francis's successor did not have to be his likeness, for "every pope has a message for the world today".

Many of the mourners expressed hope that the next pope would follow Francis's example, at a time of widespread global conflict and growing hard-right populism.

"I hope we get another pope as skilled as Francis at speaking to people's hearts, at being close to every person, no matter who they are," 53-year-old Maria Simoni from Rome said.

Marx said the debate over the next pope was open, adding: "It's not a question of being conservative or progressive... The new pope must have a universal vision."

- 'Whole world present' -

Italian Cardinal Pietro Parolin -- who was secretary of state under Francis and is a front-runner to become the next pope -- led a mass Sunday morning in St Peter's Square, which drew 200,000 people according to the Vatican. Many were part of Jubilee youth groups.

He told youngsters from Europe, the US, Latin America, Africa and Asia, that Francis "would have liked to meet you, to look into your eyes, and to pass among you to greet you".

"With you here, the whole world is truly present", he said, to applause.

More than 220 of the Church's 252 cardinals were at Saturday's funeral. They will gather again on Sunday afternoon at Santa Maria Maggiore to pay their respects at Francis's tomb.

Only cardinals under the age of 80 are eligible to vote in the conclave. There are 135 currently eligible -- most of whom Francis appointed himself.

But experts caution against assuming they will choose someone like him.

Francis, a former archbishop of Buenos Aires who loved being among his flock, was a very different character to his predecessor Benedict XVI, a German theologian better suited to books than kissing babies.

Benedict in turn was a marked change from his Polish predecessor, the charismatic, athletic and hugely popular John Paul II.

Some cardinals have admitted the weight of the responsibility that faces them in choosing a new head of the world's 1.4 billion Catholics.

"We feel very small," Hollerich said last week. "We have to make decisions for the whole Church, so we really need to pray for ourselves."
