The Local AFP/The Local 14:19 CEST The Spanish government on Thursday blocked the auction of a 17th-century oil painting in Madrid on suspicion that it may actually be a lost masterpiece by the Renaissance artist Caravaggio. Writing on Twitter, Culture Minister Jose Manuel Rodriguez Uribes said the painting had been declared “not for export… on suspicion it may be a Caravaggio”. Entitled “Coronation with Thorns”, the canvas shows Jesus before his crucifixion and was attributed in the auction catalogue to “the entourage of (Spanish artist) Jose de Ribera”.
