This issue focuses on the world’s most fascinating city, Jerusalem—on its excavations and on its archaeological restorations.

A major dig which is exposing the original City of David is also exploring the city’s ancient underground water systems. Dig director Yigal Shiloh is the author of “Jerusalem’s Water Supply During Siege—The Rediscovery of Warren’s Shaft,” in which he tells how mountain climbers and mining engineers helped him reopen the interior of Jerusalem’s oldest water system. When not digging, Dr. Shiloh is a lecturer in archaeology at the Hebrew University of Jerusalem. This academic year he spent the fall semester lecturing at the Universities of California at San Diego and the winter semester teaching at Harvard. A Ph. D. graduate of Hebrew University’s Institute of Archaeology, Shiloh has also excavated at Arad, Masada, Megiddo, Hazor and in Jerusalem’s Citadel.
