This book presents for the first time the complete corpus of equipment for horses excavated by The Hasanlu Project in the Iron II level at Hasanlu Tepe, Iran. The equipment is varied, extensive, and in a context sealed as buildings collapsed during the violent surprise attack and resulting fire that destroyed the town. The equipment, most still in its primary location ready for active use, make it of particular, if not unique, importance. It is also remarkable in the quantity recovered, its variety and richness, the functional types that could be identified (riding, draft, ceremonial), and the amount that could be reconstructed. Its life context gives new information about equipment and usage not otherwise available and allows suggestions for the layered importance of the horse as evidenced by the equipment. No other book presents equipment for horses in a similar context and quantity because the preservation at Hasanlu is unique for this part of the Near East in this time period. The equipment also provides new insight into space use in Hasanlu, one of the most important Iron Age sites in northwest Iran. Findspots yield information about building use and reuse, some as stables. These and architectural alterations provide unique information regarding changes to the town over time, some of which most likely reflect changes in the dynamics of the region.
