Masterpiece of the week

Rogier van der Weyden and workshop, The Exhumation of Saint Hubert, late 1430s

This mesmerising masterpiece of realist art is nearly 600 years old. It portrays a history far older. In a gothic cathedral, gathered clerics are astounded to see the perfectly preserved body of a long-buried saint being raised intact from its tomb. The dead saint seems only to be sleeping. Rogier van der Weyden, one of the Flemish geniuses who revolutionised European art in the 15th century, recreates this scene with hypnotic intensity and compelling dramatic detail. This is not only a lifelike picture, but one that still possesses uncanny power many centuries after it was created.
• National Gallery, London
