It is of course, a fruitless—if interesting—speculation, to ask oneself what would have happened to Christianity if the camera had been invented during Christ’s lifetime. Most of us probably find it pretty well impossible to picture Divinity trapped between the stiff pages of a family album or to conceive of a God crying out on a cross while, a few yards away, someone discards a flash or fiddles with a light metre. As we actually experience it, the problem arises in muted form, and is largely a matter of reconciling noble architecture, the tourist industry and religious sentiment. We have all seen those glossy volumes with coloured plates of pilgrim multitudes, a white figure with hand blessingly uplifted and that better-looking, younger nun, smiling instamatically over her own viewfinder. Granted then that the camera create; curious problems of credibility, it is perhaps not too outrageous to suggest—at least very tentatively— that if this medium had existed two milennia ago Christianity as we know it with its mystery and its historicity simply would not have happened.

If, however, there had been a photographic record dealing with the beginnings of Christianity, I believe that an American, Diane Arbus, who committed suicide in 1971, would have been better equipped than most people to salvage something meaningful from a past that we have magnified and isolated, and interpreted repeatedly into the patterns of our preconceptions. Quite recently her work has been on view at the Hayward Gallery and in March 1974 The Sunday Times ran an illustrated article on the exhibition in its supplement and asked several well-known critics to give their opinions.
