Reburial and protective covering of ancient mosaic pavements: The experience of the conservation department of the Israel Antiquities Authority

Abstract

Four case studies are presented illustrating different attempts to protect excavated ancient mosaics by reburial or protective covering, with varying degrees of success, at three archaeological sites in Israel: Tel Itztaba, a site excavated between 1991 and 1994 where planning for reburial at the outset of the excavation could have prevented considerable losses; Khirbet Minya (Horvat Minim), a site excavated in the 1930s, reassessed after four years of reburial; the Promontory Palace at Caesarea Maritima, a site excavated in 1978, partially destroyed by the sea, reburied and regularly monitored since 1994; and an experimental test site at Caesarea Maritima. These examples demonstrate the importance of planning, monitoring and maintenance for successful reburial, and allow an assessment of which materials and methods performed better than others.
