“A painting that spent more than a century in the storerooms of a provincial Italian museum will be attributed Wednesday to one of the greatest artists of the Renaissance. The attribution to Andrea Mantegna (1431-1506) has the backing of Keith Christiansen of the Metropolitan Museum of Art in New York, the world’s leading expert on the artist. It means the painting, a wooden panel depicting Jesus’s resurrection, may be worth about a thousand times more than was previously thought: between $25 million and $30 million.”
