The series that reveals stories behind famous artworks returns, beginning with an examination of Eugene Delacroix 's response to the July revolution of in France. Delacroix's vibrant portrayal of the bare breasted figure of Liberty leading a rabble over a barricade was taken up as a symbol of revolution across the country.

The series that reveals the stories behind famous artworks continues with an examination of the favourite picture of the artist who painted it - the 17th-century Dutch master Johannes Vermeer. This sublime symbol-laden interior remained in his possession until his death, despite the family being in dire financial straits. A later admirer was Adolf Hitler , who liked it so much that he bought it.

An armoured knight in the thick of battle astride his white charger forms the central figure of a dramatic 15th-century masterpiece by Paolo Uccello. The painting, in three panels, depicts scenes from the battle of San Romano fought between Florence and Siena in 1432. Using one-point perspective Uccello achieved one of the greatest portrayals of men in close combat. Coveted through the centuries the panels became the victims of an extraordinary art crime.

"Bedlam", "scandal", and "hilarity" were some of the words used to describe Georges Seurat's portrayal of Parisians enjoying an outing on the banks of the River Seine. Now it is seen as one of the most popular paintings ever created, and hailed as a masterpiece of pointillism - or divisionism as Seurat preferred to call his technique.

This erotically charged and hugely popular example of Art Nouveau fused with Symbolism has been the subject of intense speculation since its unveiling in 1908. Who are the two lovers in a rapturous embrace? Is the man or woman in control? And, most tantalisingly, could it depict the artist, a man whose sexual appetite was on a par with Casanova's? Germaine Greer, John Malkovich and former Erotic Review editor Rowan Pelling share their thoughts.
