In the film The Belly of an Architect, an architect from Chicago organizes an exhibition of his favourite architect Etienne-Lous Boullée (1728-1799). I wrote an account of this hypothetical exhibition as though it had been seen by an unlikely Boullée contemporary -- Jane Austen (1775-1817). She made a prim but perceptive account of her progress through the corridors and halls of the Vittoriano in the centre of Rome -- a building constructed long after both of these eminent personages were dead.
