I've spent a lot of time in London over the last few years and I liked the idea of the Mughal emperor Babur meeting with modern-day disaffected youth and talking to them about their actions. He was a sharp literary critic who could be very sweeping and cruel about poetry if he thought it was bad poetry, and he said some fantastic things that I quoted word for word in the opera. I read the Baburnama – the memoirs of Babur – and quoted lines from it. "Writing badly will make you ill.” What a beautiful thing to say. I read that book and I thought, how dramatic! If he had been a figure in western history it would have been an opera. War, murder, love, tragedy, poetry. It always jumped out at me as something worth doing.
