Diana Wynne Jones died earlier this year. We never met. But she did write an autobiography—long for an essay, and painfully short for the book it should have been. You can read the whole thing here, and you should. It includes a violent encounter with Beatrix Potter.
This passage is not really about bedtime stories, but it does involve both bedtime and stories:
Then my grandfather went into the pulpit. At home he was majestic enough: preaching. he was like the prophet Isaiah. He spread his arms and language rolled from him, sonorous, magnificent, and rhythmic. I had no idea then that he was a famous preacher, nor that people came from forty miles away to hear him because he had an almost bardic tendency to speak a kind of blank verse – hwyl, it is called, much valued in a preacher – but the splendour and the rigour of it nevertheless went into the core of my being. Though I never understood one word, I grasped the essence of a dour, exacting, and curiously magnificent religion. His voice shot me full of terrors. For years after that, I used to dream regularly that a piece of my bedroom wall slid aside revealing my grandfather declaiming in Welsh, and I knew he was declaiming about my sins. I still sometimes dream in Welsh, without understanding a word. And at the bottom of my mind there is always a flow of spoken language that is not English, rolling in majestic paragraphs and resounding with splendid polysyllables. I listen to it like music when I write.
