A 500-year-old work of art - believed to be by Leonardo da Vinci and depicting Jesus Christ - sold for $450m (€382m), setting a new art auction record, at Christie's in New York.
The price dwarfed the previous record for the most expensive piece of art sold at auction, set at $179.4m for Pablo Picasso's 'The Women of Algiers (Version O)' by Christie's in 2015.
The auction house says 'Salvator Mundi' or 'Saviour of the World' is one of fewer than 20 Da Vinci paintings in existence that are generally accepted as from the Renaissance master's own hand.
All other known paintings by Da Vinci are held in museum or institutional collections.
Dated by the auction house to around 1500, the oil on panel sold after 18 minutes of frenzied bidding in a historic sale, the star lot of the November art season in the US financial capital.
Whoops and applause rippled through the showroom as the bids quickly escalated into uncharted territory, led by rivals on the telephone.
"An historic moment here. We'll wait," said auctioneer Jussi Pylkkanen in a brief pause in bidding at $300 million.
He eventually hammered the painting at $450m. The final price came to $450.3m including the buyer's premium.
The work was exhibited at The National Gallery in London in 2011, after years of research trying to document its authenticity after it was found, mistaken for a copy, in a regional US auction in 2005.
Before that it had disappeared for years, previously fetching a mere £45 ($60 in today's money) in 1958 as a believed copy.
Christie's said pre-sale that the painting's rarity was difficult to overstate.
For years it was presumed to have been destroyed, emerging only in 2005 when it was purchased from a US estate.
"For auction specialists, this is pretty much the Holy Grail," Loic Gouzer, co-chairman of Christie's Americas postwar and contemporary art department, said. "It doesn't really get better than that."
The price throws shade at its Russian billionaire seller, who has sued a Swiss art dealer in Monaco for allegedly swindling him into parting with $127.5m for the work in 2013.
Dmitry Rybolovlev, the boss of soccer club AS Monaco, accuses Yves Bouvier of conning him out of hundreds of million of dollars by overcharging him on a string of deals, and pocketing the difference.
'Salvator Mundi' had been at the heart of that court battle.
Mr Bouvier bought the work at Sotheby's for $80m in 2013. He resold it within days to the Russian tycoon, for $127.5m, netting a $47.5m profit.
Mr Bouvier denies any wrongdoing.
