It took all of six minutes for Massimo Pulini to realise that the small oil painting due to go under the hammer in Madrid earlier this month with a guide price of â¬1,500 could be worth millions. At 9.48pm on March 24th, Pulini, a 63-year-old professor at Bologna Fine Arts Academy, received an email request for an evaluation. Sent by an antiques dealer and friend of Puliniâs, it included a photo of a luminous oil painting of the scourged Christ. At 9.54pm, Pulini sent a reply that would echo across the art world: âDamn! This is a Caravaggio! Where the hell did you find it?â
