Hieronymus Bosch painted clog ships, fish soldiers, armoured creatures with insect wings and scales gobbling human limbs. In the recesses of his paintings you might find a spoonbill, wearing a hooded cape, sitting down to a supper of bird-claw at a table set with white linen and pewterware. His picture of Saint Wilgefortis – usually in the Accademia in Venice, but currently on display at an exhibition in ’s-Hertogenbosch, the town where he lived and worked – is perhaps one of his least strange paintings. It shows a bearded woman being crucified.
