Extract from Wegener's Jigsaw by Clare Dudman
That night I wrote to Koppen. I wanted to know whether he too had ever noticed this fitting together of the pieces. Maybe, I said, not just America and Africa had been joined, but all the continents had once been part of a huge supercontinent .... Then I stopped. The vision of a continent splitting apart, and then these two enormous fragments drifting away from each other over thousands of miles across the sea, suddenly seemed too fantastic. I put my pen down. I imagined Koppen's face. It looked puzzled and concerned. It was a ridiculous notion.
