This book forms the final report of the underwater excavation which the author directed at Cape Gelidonya, Turkey, in 1960, for the Univ. Museum of the Univ. of PA. The formation of such a novel excavation, involving divers and equipment from five countries, took an unusual amount of paperwork. This report was written with the collaboration of Peter Throckmorton, Joan du Plat Taylor, J.B. Hennessy, Alan R. Shulman, and Hans-Gunter Buchholz. Contents: The Discovery, The Excavation, Condition and Treatment of Finds, The Ship and Its Lading, The Ingots, The Bronzes, The Pottery, The Stone Objects, Miscellaneous Finds, The Weights, The Scarabs, The Cylinder Seal, Basketry and Matting. Bibliography. Illustrations. A print on demand publication.
