LONDON — “Is it time to stop looking at Gauguin altogether?”

That’s the startling question visitors hear on the audio guide as they walk through the “Gauguin Portraits” exhibition at the National Gallery in London. The show, which runs through Jan. 26, focuses on Paul Gauguin’s depictions of himself, his friends and fellow artists, and of the children he fathered and the young girls he lived with in Tahiti.

The standout portrait in the exhibition is “Tehamana Has Many Parents” (1893). It pictures Gauguin’s teenage lover , holding a fan.

The artist “repeatedly entered into sexual relations with young girls, ‘marrying’ two of them and fathering children,” reads the wall text. “Gauguin undoubtedly exploited his position as a privileged Westerner to make the most of the sexual freedoms available to him.”
