Another attendee at the party was Charles Jencks, who has been man-aboutLondon this season. He made a heartfelt contribution to a postdinner discussion at the AA on this summer's great debate, as started by Graham Morrison: the place of the icon and its relation to context. Charles has generally read the latest book on any subject you care to mention, and therefore has an advantage in debating it. On this occasion he had gone one better, by actually writing a book, now with its publisher, which no one has therefore had the chance to read. It is called The Iconic Building - the successor to the monument, and will be published next spring. I don't think it is giving away too much to say that in his league table of icons, Ronchamp comes first.
