Hazor was the largest city in Palestine in the Canaanite period and cultural and a commercial centre of some consequence in the Fertile Crescent, as well as being an important bastion of the Israelite Kingdom. Professor Yigael Yadin conducted extensive excavations on the site of the town between 1955 and 1969 as Director of the James Rothschild Hebrew University Expedition. Professor Yadin's 1970 Schweich Lectures first describe the history of Hazor as recorded in the Egyptian Execration Texts, the Mari archives, Egyptian New Kingdom documents, the Armarna Letters, and finally the Old Testament. They proceed to give an authoritative account of the fascinating results achieved in the five seasons of excavation. These include the large lower city with its earthen fortifications, the many temples, the Solomonic City, the Israelite water-system, as well as a chapter on the author's discoveries of the corresponding periods at Megiddo.
