Jules Barbey D'aurevilly said this quote

If writers only dared to dare, a Suetonius or a Tacitus of the Novel could exist, for the Novel is essentially the history of manners, turned into a story and a play, as is History itself often enough. And there is no other difference than this: that the one, the Novel, cloaks its manners under the disguise of invented characters, while the other, History, provides names and addresses. Only, the Novel probes much deeper than history. It has an ideal, and History has none; it is limited by reality. The Novel also holds the stage much longer. (A Woman's Vengeance)
