The Doctor Who crew are fond of their encounters with historical characters. In his time, and let's face it he has infinite supplies of it, the Doc has rubbed shoulders with Shakespeare, Charles Dickens and Agatha Christie, and recently weathered the Blitz with Winston Churchill. For this one, "Vincent and the Doctor", le Docteur voyaged back to 19th-century Provence to straighten out a puzzling temporal kink.

This exhibition may claim to reveal the real Van Gogh through his letters, but what of the Sunflowers, the Self-Portrait With Bandaged Ear, oh, and Starry Night, with its roiling night sky and dark, mysterious cypress tree? What even of the dizzying Night Café, with its migraine-inducing electric lamps, its violent clash of reds and greens and the walls that threaten to collapse inwards, as if the painter had been hitting the absinthe all night?

This Saturday The Real Van Gogh: The Artist and His Letters opens at the Royal Academy of Arts - it is reviewed by Fisun Güner elsewhere. Organised in collaboration with the Van Gogh Museum in Amsterdam, it is the first major exhibition of Van Gogh's work in this country for 40 years.
