What makes a book a history? In the eighteenth century, novelists called their books “histories,” smack on the title page. No one was more brash about this than Henry Fielding, who, in his 1749 “History of Tom Jones, a Foundling,” included a chapter called “Of Those Who Lawfully May, and of Those Who May Not Write Such Histories as This.” Fielding insisted that what flowed from his pen was “true history”; fiction was what historians wrote.
