Our knowledge of ancient Greece has been transformed in the last century by an increased understanding of the cultures of the Ancient Near East. This is particularly true of ancient religion. This book looks at the relationship between the religious systems of Ancient Greece and the Hittites, who controlled Turkey in the Late Bronze Age (1400-1200 BC).The cuneiform texts preserved in the Hittite archives provide a particularly rich source for religious practice, detailing festivals, purification rituals, oracle-consultations, prayers, and myths of the Hittite state, as well as documenting the religious practice of neighbouring Anatolian states in which the Hittites took an interest. Hittite religion is thus more comprehensively documented than any other ancient religious tradition in the Near East, even Egypt. The Hittites are also known to have been in contact with Mycenaean Greece, known to them as Ahhiyawa. The book first sets out the evidence and provides a methodological paradigm for using comparative data. It then explores cases where there may have been contact or influence, such as in the case of scapegoat rituals or the Kumarbi-Cycle. Finally, it considers key aspects of religious practices shared by both systems, such as the pantheon, rituals of war, festivals, and animal sacrifice. The aim of such a comparison is to discover clues that may further our understanding of the deep history of religious practices and, when used in conjunction with historical data, illuminate the differences between cultures and reveal what is distinctive about each of them.
