[File:Modern document hypothesis.svg|thumb|240px|Diagram of the Documentary Hypothesis. The documentary hypothesis (DH), sometimes called the Wellhausen hypothesis, proposes that the Torah (the first five books of the Bible) was derived from originally independent, parallel, and complete narratives, which were subsequently combined into the current form by a series of redactors. The number of these narratives is usually set at four, but the precise number is not an essential part of the hypothesis.
