History transforms the past, instead of explaining it. When a historian writes a work of history, he develops a new view of the past. All works of history are a compromise between what really happened, and how the historian has interpreted the events. No historian can take all the historical events of any age into account. He concentrates on some of the events which he considers important and he ignores the other events—no work of history can provide a full picture of the past. There are as many versions of the past as there are works of history.
