 Whybray's own, alternative hypothesis, is based not on the documentary model but on a fragmentary model.He suggests that the Pentateuch was the product of a single author (not the four authors and multiple editors of the documentary hypothesis) working at some time in the 6th century BC "[with] a mass of material, most of which may have been of quite recent origin and had not necessarily formed part of any ancient Israelite tradition" (p. 242).Whybray saw this author as a national historian, aware of contemporary Greek history and writing in conscious imitation of Greek models, with the aim of extending the existing Deuteronomic history backwards in time to create a national history of the Israelites from the creation of the world.
