I had a misspent youth. During the period when most normal adolescents were playing Grand Theft Auto or discovering ten interesting facts about Pamela Anderson, I am afraid that I would take the tube by myself — aged about 13 — and visit the British Museum.

I would walk through the cat-headed Egyptians and the cloven-hoofed Babylon-ians and the typewriter-bearded Assyrians, and all the other savage and ludicrous Near Eastern divinities, until I penetrated the innermost and holiest shrine of London’s greatest cultural temple, the Duveen galleries.
