ROME — The once-in-a-lifetime exhibition took three years to come together. Organizers arranged for the careful transport of Raphael masterpieces loaned from London, Washington, Florence, Madrid. The insurance bill was 4 billion euros.

One 1510 painting, “The Alba Madonna,” had belonged over the centuries to Spanish nobility, the emperor of Russia and American banker Andrew Mellon, who acquired it in a secret Soviet art sell-off.

At last, it was back in Italy for the first time since the 17th century.

Just in time for the pandemic.

The exhibition marking the 500th anniversary of Raphael’s death coincided with Italy’s coronavirus lockdown and was halted in early March after all of three days.

“It was as if the works were in a bank vault,” said Marzia Faietti, one of the collection’s two curators.

Even as Italy now moves to reopen its famed cultural sites, including the Raphael exhibition, the lasting restrictions of the pandemic have dramatically changed how widely they can be seen.

There has perhaps never been a better, or harder, time to experience Italy’s beauty and treasure.

Monuments such as the Colosseum require temperature checks and maintain tight entrance quotas. Wonders such as the Sistine Chapel allow dinner-party-size gatherings but not the usual arena-size crowds. And exhibitions intended as international events — such as the one devoted to Raphael — have had to scale back their daily capacity, to roughly one-third of what was initially imagined, to adhere to social distancing rules.

Italy plans to lift its internal travel restrictions and open its borders to European tourists Wednesday. But tourism is expected to remain low through the summer, leaving cultural sites to Italians with masks and reserved tickets.

“This exhibit could have been a blockbuster — seen by thousands and thousands of people,” said Mario De Simoni, president of the government venue in Rome that is hosting the exhibition. De Simoni in 2010 helped put together a 110-day Caravaggio exhibition seen by 600,000 people. The Raphael exhibition, lasting 90 days, will probably be capped at about 80,000 — groups of six entering every five minutes.

There is one upside, De Simoni said.

“Those who do see it will experience it under ideal conditions,” he said.

Speaking Monday near a meticulous replica of Raphael’s tomb, one day before the event reopened to the public, De Simoni was still searching for ways to expand access to even a few more people.

“If I have enough requests, I’ll keep the [exhibition] open until 2 or 3 a.m.,” Di Simoni said. “We could do that.”

Rome’s restaurants reopen. Will diners return? Or just delivery riders?

The exhibition — at the Scuderie del Quirinale, a onetime carriage house that is an annex of the country’s presidential palace — looks much as it did in March. But now red and white floor stickers show a mandatory footpath and provide reminders of the distance people need to keep. The cafeteria is closed but the bookstore is open.

Given the cap on attendance, De Simoni noted that the experience for exhibition-goers wouldn’t feel so different from the private tour he provided two Washington Post reporters and a photographer.

As De Simoni walked from one room to the next, he gave the broad strokes of the life of Raphael — a genius of the High Renaissance who died at 37 — while stopping at some of his favorite pieces in wonderment.

“This is maybe the most beautiful portrait of the Renaissance,” he said at one painting, of Baldassare Castiglione.

“Sublime,” he said at another, “The Alba Madonna.” “There is no mistake here.”

He noted that Raphael, during his decade in Rome, had worked under two popes, Julius II and Leo X. Raphael painted portraits of both of them. They’re on display on separate floors.

In another room, De Simoni touched on something else: the logistics of bringing the paintings together.

“From Bologna,” he said, pointing at the first. “From Naples. From Florence. From Madrid, from Madrid.”

Originally, the paintings and drawings were supposed to be returned to museums around the world in June, when the exhibition was scheduled to end. But during the lockdown, organizers realized their only chance to relaunch the exhibition was to get on the phone, send emails, rewrite contracts.

The museums, including the National Gallery of Art in Washington, were willing to extend the loans.

The Scuderie del Quirinale then had to figure out a plan to take care of the art for an extended period. While the exhibition was shuttered, police continued to guard the doors. Once a week, an official made the rounds to check on the paintings. The exhibition hall was darkened, other than emergency lights, and drawings — the most sensitive to light damage — were placed under black protective sheets. Normally, after drawings are exposed for several months during an exhibition, they are placed in dark storage for resting time. Keeping them in the dark amid the shutdown was the only way to allow the exhibition to eventually resume.

“Deterioration exists even under the best conditions,” Faietti said. “Our task is that of making it so that the works’ natural life cycle is as slow as possible.”

On Monday, in preparation for the reopening, the black protective sheets were gone. The lights were back on. In the last room of the exhibition, which includes Raphael’s most well-known self-portrait, press official Federica Salzano noted that tiny thermometers that had been measuring microclimates within protective glass cases had been removed.

The following day, the people with tickets would arrive.

“I was telling everyone that we’ll make it, we’ll make it and reopen it,” Faietti said. “I wasn’t sure, but I was hoping we would. Ultimately, all this was like praying.”
