In telling the history of cities such as Jerusalem or Istanbul, since the subject matter is human civilisation itself, the challenge is to bring into focus the grandeur and the imaginary at the core of each era, as well as the driving impulses of founders who conjured these cities into existence. Bettany Hughes meets the challenge with remarkable aplomb in her book on Istanbul, showing how multiple impulses may be discerned in the material culture. Racy in tone, even when the research is meticulous, the book’s anecdotal style encourages “the mind and spirit to travel”.
