McMaster University\u2019s new exhibition, The Unvarnished Truth<\/a>, highlights the role that nuclear technology plays in exploring the history behind paintings. The exhibition features nine paintings, including works by Van Gogh and Reubens. And art experts are using radiography to explore the paintings\u2019 secrets.<\/p>\n

McMaster researcher Brandi Lee MacDonald points to a painting attributed to Peter Paul Reubens. \u201cWe were able to tell that it was cut out of an early larger painting, so it leads us to question the history of this object,\u201d she says. \u201cWhat happened to the rest of it?\u201d<\/p>\n

MacDonald, who works in the McMaster\u2019s Department of Applied Radiation Sciences, led the exhibition\u2019s development, bringing together 30 researchers from across continents and disciplines. Over five years, they used a variety of techniques to look at nine paintings \u2013 especially the pigments within the paint and to see what is going on beyond the canvas.<\/p>\n

\u201cOne of the art historians identified the sitter in one of the portraits. Finding out who this person was is rare,\u201d says McMaster professor Fiona McNeill, a member of the research team.<\/p>\n

In one example, using a neutron beam, the team inspected the wood beneath the painting, discovering damage and gaining knowledge that will help curators to repair and care for the painting.<\/p>\n

\u201cFor the Van Gogh painting, there is a different painting underneath the original layer,\u201d says MacDonald. \u201cHe is famous for recycling his canvases to save money, and we were able to see features of a previous painting underneath.\u201d<\/p>\n

The exhibition will remain at the McMaster Museum of Art<\/a> in Hamilton, Ontario until December 19th<\/sup> From there, it moves next spring to Edmonton, then to Thunder Bay next fall before concluding its tour in early 2017 in Kingston, Ontario.<\/p>\n","protected":false},"excerpt":{"rendered":"
