AMSTERDAM: A gloomy self-portrait by Vincent van Gogh was declared genuine on Monday after decades of uncertainty, experts identifying it as the only work painted by the Dutch master while he suffered from psychosis.

The “Self Portrait (1889)” — which shows the artist giving a haunted sideways glance against a swirling blue and yellow background — was confirmed as authentic by the Van Gogh Museum in Amsterdam.

Questions were first raised about whether the painting — owned by the National Gallery in Oslo, Norway — was genuine as far back as 1970 but the Norwegian museum finally decided to end the doubts only in 2014, sending it to Dutch experts.

Using X-ray analysis of the canvas, studies of the brushwork and references to letters to his brother Theo, experts established it was painted while Van Gogh was in an asylum in Saint-Remy in France in the late summer of 1889.

“The self-portrait that is behind me has been doubted for a very long time,” Louis van Tilborgh, senior researcher at the Van Gogh Museum, said as he showed off the picture.

“It’s a work of art that for all kinds of reasons was by him but nevertheless also had certain aspects that were different from other pictures.

“So we had to find an explanation for that and that was difficult, but I think we’ve solved that and so we’re proud that we’ve more or less given the work back.”
