The recent excavations at Tell Sabi Abyad in northern Syria have made an important contribution to our knowledge of the Late Neolithic in the Near East. The site has yielded wholly new and, sometimes, spectacular data on the history of cultural development in the 6th millennium B.C., which actually belongs among the poorest known in the region so far. This extensive interim report presents a detailed and lavishly illustrated description of the stratigraphy and architecture, pottery, flint and obsidian industries, seals and sealings, figurines and other small finds. In addition, essential data are provided on the ancient landscape and the faunal and floral remains.
