PARIS (Reuters) - A painting found in the attic of a house in southwest France was attributed to the Italian master Caravaggio by private French experts who hailed its discovery on Tuesday as a great event in the history of art. It depicts Biblical heroine Judith beheading an Assyrian general, and was discovered during the investigation of a leak. It could be worth 120 million euros ($137 million), the Eric Turquin art expert agency said in a statement. The painting is thought to have been painted in Rome in 1604-1605 by Michelangelo Merisi, known as Caravaggio, and is in exceptionally good condition.
