Patriarchal age

The patriarchal age is the era of the three biblical patriarchs, Abraham, Isaac and Jacob, according to the narratives of Genesis 12–50 (these chapters also contain the history of Joseph, although Joseph is not one of the patriarchs). It is preceded in the Bible by the primeval history and followed by The Exodus. The Bible contains an intricate pattern of chronologies from the creation of Adam, the first man, to the reigns of the later kings of ancient Israel and Judah. Based on this chronology and the Rabbinic tradition, ancient Jewish sources such as Seder Olam Rabbah date the birth of Abraham to 1948 AM (c. 1813 BCE) and place the death of Jacob in 2255 AM (c. 1506 BCE). Out of this heated debate between the various theories of biblical criticism and traditional, religious interpretations was born biblical archaeology, a form of archaeology different from others in that it sought not to discover and interpret mute evidence, but to validate or invalidate the historicity of the patriarchs and the events surrounding their lives, as described within the Bible. The most eminent of early biblical archaeologists was William F. Albright, who believed that he had identified the patriarchal age in the period 2100–1800 BC, the Intermediate Bronze Age, the interval between two periods of highly developed urban culture in ancient Canaan. Albright argued that he had found evidence of the sudden collapse of the previous Early Bronze Age culture, and ascribed this to the invasion of migratory pastoral nomads from the northeast whom he identified with the Amorites mentioned in Mesopotamian texts. According to Albright, Abraham was a wandering Amorite who migrated from the north into the central highlands of Canaan and the Negev with his flocks and followers as the Canaanite city-states collapsed. Albright, E. A. Speiser and Cyrus Gordon argued that although the texts described by the documentary hypothesis were written centuries after the patriarchal age, archaeology had shown that they were nevertheless an accurate reflection of the conditions of the 2nd millennium BC.
