This much has already been ascertained by the excavations made by the German expedition under Professor Winckler at Boghaz-Keui, north of the Halys, the site of the Hittite capital. But there are many other sites in Asia Minor and northern Syria where Hittite culture once flourished, and where, therefore, discoveries similar to those which have startled the scientific world at Boghaz-Keui may be expected to be made. Some of these sites were examined by Professor Garstang in his preliminary journeys of exploration; at another he has begun the work of excavation and brought to light important remains of art and antiquity. Sakje-Geuzi lies at a short distance from Sinjerli, where German excavators have discovered monuments which form the chief attraction of the Hittite section in the Museum of Berlin. The mound of Sakje-Geuzi represents a continuous history of unnumbered centuries. The earlier strata are the accumulation of a neolithic people; above them come the ruins of Hittite and Aramæan builders. The temple disinterred by Professor Garstang shows us what Hittite art was like in the Syria of the tenth and following centuries before our era, and enables us to guess at the character of the cult that was carried on in it. In the following pages he has given an account of his work and the conclusions that may be drawn from it. This, however, occupies but a small portion of his book. Its main purpose is to review our present knowledge of Hittite history, art, and archæology; to describe the Hittite monuments now known to exist, and to trace the story of the Hittite empire as it has been revealed to us by recent discoveries.
