White, Michael. Foundation, Isaac Asimov: A Life of the Grand Master of Science Fiction, p. 83, Carroll & Graf Publishers, 2005 ISBN0-7867-1518-9. Quote: "Asimov was travelling on the subway reading ... Iolanthe. The illustrations and their military theme started him thinking in terms of armies, wars, and empires. Before he had arrived at [his publisher's] office he had the idea of writing about a galactic empire, based on the historical structure, rise, and fall of the Roman Empire."
