A portrait of Rembrandt, long believed to be painted by one of his pupils, has been attributed to the 17th-century Dutch master.
The crude brushwork led researchers in 1968 to conclude that the painting, which features the artist’s signature and is dated 1635, was by one of Rembrandt’s students. But a recent investigation led by Ernst van de Wetering, the world's leading Rembrandt expert, found that the painting was indeed by Rembrandt.
"Over the past 45 years, we have gathered far more knowledge about Rembrandt's self-portraits and the fluctuations in his style," he said.
The painting, now estimated to be worth $30 million, was donated in 2010 to Britain's National Trust by Edna, Lady Samuel of Wych Cross, the wife of a wealthy property-developer and major art collector. The piece hangs in Buckland Abbey in southwestern England, the former home of Sir Francis Drake.
