The Private Life of a Masterpiece

The first moment in the Christmas story is the arrival of the Archangel Gabriel to tell Mary that she has been chosen to give birth to the son of God. Many painters have depicted this miraculous event, but none better than the great Flemish painter Jan Van Eyck. As befits a man who seemed to mix espionage with painting for his patron, Eyck's picture is full of symbols and half-concealed messages.

A closer look at the image that inspired a thousand Christmas cards: Brueghel's Census at Bethlehem. It depicts Mary and Joseph's arrival in the town - but also offers a glimpse into life in a Netherlands village under the rule of foreign invaders.

The series concludes with a look at Paul Gauguin 's interpretation of the Nativity scene, a distinctively modern piece in which he depicted the Madonna as a young Polynesian woman, using his pregnant mistress as his model. Far removed from traditional images, it has been hailed for its relevance to the contemporary world.
