Despite Iran’s pious reputation, Tehran may well be the least religious capital in the Middle East. Clerics dominate the news headlines and play the communal elders in soap operas, but I never saw them on the street, except on billboards. Unlike most Muslim countries, the call to prayer is almost inaudible. There has been a rampant campaign to build new mosques, yet more people flock to art galleries on Fridays than religious services. With the exception, perhaps, of Tel Aviv, I had visited nowhere in the Middle East where people read as voraciously as Tehran. “The Handmaid’s Tale”, Margaret Atwood’s dystopian fable of women enslaved to a theocratic caste, is a particular favourite, the owner of one bookstore told me.
