Volcano: Turner to Warhol Compton Verney, until 31 October On my desk is a lump of lava, a memento of Vesuvius. It doesn’t look like much, but neither does the volcano from the cinder track that winds around to its summit. From close to, Vesuvius is a giant ash heap; it’s from across the bay that the magic works. Never does distance lend more enchantment to the view than in the case of volcanoes: when they’re exploding they’re plain dangerous, and when not they’re really rather dull. Their allure is as elusive as a rainbow’s, and it was in rainbow colours that Andy Warhol painted Vesuvius in 1985, making it look like a Neapolitan ice cream blown under pressure through the end of a cone.
