A £50m painting, described as one of the most significant public purchases of art in recent years, is to go on display in Cardiff.

Diana and Actaeon by 16th Century artist Titian, will be shown at the National Museum next April as part of a tour. It was acquired after two years of fund-raising in Scotland in 2009. Anne Prichard from the museum described Titian as the greatest artist in Renaissance Venice.

It will be displayed in Cardiff between 19 April and 17 June 2012 as part of a UK tour that takes the work to galleries where it has never been seen before.
