On the painting Hanbury Hall
Based on actual features in the gardens of Hanbury Hall, the blue gazebo frames the view across the lawn, of another blue gazebo, or perhaps it is, impossibly or paradoxically, a view of itself. The trellis frames the view of the church spire. The swallows are circling freely in and out of the gazebo, as the sitter catches sight of one. The birds have their own world, and are as oblivious to any meaning we might see in the scene, as they are unbothered by the content of the green bag on the seat.
