What Did Jericho's Archaeological Layers Reveal in 1580 BC?

Kathleen Kenyon's work at Jericho in the mid-20th century was groundbreaking, as she meticulously excavated the site and employed innovative stratigraphic methods. Her findings led her to date the destruction of Jericho to around 1580 BC, suggesting that the city had been abandoned by the time of Joshua's conquest. This conclusion sparked significant debate among scholars, particularly regarding the timeline of Israel's entry into Canaan as described in the Book of Joshua. Kenyon's redating of the destruction layers, previously thought to correspond with the biblical conquest, implied that Jericho had already fallen centuries earlier, challenging traditional interpretations of the biblical narrative.

However, this perspective was later contested by Bryant Wood, who reexamined the pottery and stratigraphic evidence from the site. Wood's analysis, published in Biblical Archaeology Review in 1990, argued for a destruction date closer to 1400 BC, which aligns with a 15th-century Exodus timeline. His findings reignited discussions about the historicity of the biblical account and the implications for understanding Israel's conquest of Canaan. The debate over the dating of Jericho's destruction is emblematic of broader discussions in biblical archaeology, where interpretations of material culture can significantly influence our understanding of biblical events.

The Jericho stratigraphy preserves evidence that both supports and complicates the conquest narrative. Kenyon's excavation documented a destruction layer with collapsed mudbrick walls, burned remains, and stores of carbonized grain - details consistent with Joshua 6's description of a city burned after a brief siege during harvest season. Her redating of this destruction to the Middle Bronze Age (c. 1550 BC) removed it from the conquest period, but Bryant Wood's subsequent ceramic reanalysis argued that Kenyon's pottery sample was too limited and that the destruction should be dated closer to 1400 BC. Whether the collapsed walls and burned grain belong to the 16th or 15th century BC is a question that turns on pottery typology details that specialists continue to debate.
