In 1857 an anonymous article appeared in The Builder magazine under the title Architectural “Follies”. The author used the word ‘architectural’ to distinguish from examples of folly in literature and art: he thought there were far too many books with an eccentric choice of subject, and that there were many follies ‘perpetuated on canvas’. Sadly, he failed to develop this theme, and the reader is left wondering what exactly he had in mind (the Flâneuse is making the assumption that at this date a journalist writing for a building trade magazine was almost certainly male). Happily, he was a little more forthcoming when he moved on to follies of the built variety.
