Annette Rubery, herself a scholar of Vanbrugh, has written an excellent, thoughtful review of the Soane Museum’s exhibition in exactly the spirit in which the exhibition was intended: an exploration of the status of Vanbrugh’s drawings and how they relate to Hawksmoor’s. Vanbrugh’s drawings were done at speed as outline sketches of ideas, often for small buildings, particularly at the end of his life. But the two he did of Castle Howard probably provide the best clue as to why he was commissioned to design it. He was able to convey the character of the building, if not its detail, in exactly the way that modern architects do – for example, David Chipperfield in his initial outline sketch of Hepworth Wakefield.
