Since 1985, the Leon Levy Expedition to Ashkelon, directed by Lawrence E. Stager of Harvard University, has been a leading American archaeological project in Israel. Now, the work of the project is being collected in ten final report volumes published by the Harvard Museum of the Ancient Near East. The first volume, Introduction and Overview (1985-2006), spans more than 700 copiously illustrated pages, many in full color, and includes subjects ranging from microscopic DNA to monumental architecture. In addition, Volume 1 includes plans and descriptions of every architectural phase excavated during the course of seventeen field seasons and reveals the archaeological sequence of the site and aspects of the city plan from the Bronze Age to Crusader times, with special emphasis on Canaanite (Bronze Age) and Philistine (Iron Age) Ashkelon. The chapters in this volume, by more than three dozen contributors, combine to describe Ashkelon's cultural constants and contingencies over la longue duree (3000 BCE to 1500 CE). As a result, Ashkelon 1: Introduction and Overview (1985-2006) will be an indispensable resource for investigating the maritime and terrestrial history of the southeastern Mediterranean littoral.
