The sanctuary at Kavos on Keros was discovered in 1963 in the aftermath of looting in the region of the sanctuary now designated the Special Deposit North. From 2006-2008, excavations in the Special Deposit South (now fully published in Volumes II and III of the present series), clarified the nature of the deposits and the materials found there. This volume publishes the sculptural fragments from the Special Deposit North, recovered in excavations in 1963 and 1967, in a campaign of surface survey and excavation in 1987, and collected by archaeologists over the past six decades, or discovered by locals. The material is better preserved than most of the material from the Special Deposit South, and offers important insights into earlier phases of Cycladic sculpture, monumental sculptures, and sculptures of special type, such as seated or standing figures, including musicians and groups. The present volume completes the publication of the entire sculptural assemblage recovered in approved excavations from the sanctuary at Kavos, and a number of conclusions are offered on the basis of the complete assemblage.
