This volume analyses the Greek and Latin inscriptions and sculptures found within the sanctuary of Jupiter Dolichenus at Dülük Baba Tepesi, a mountain near the ancient city of Doliche in the modern province of Gaziantep (South-East Turkey). The mountain summit has been investigated since 2001, by a team from the Forschungsstelle Asia Minor (University of Münster) in cooperation with the Turkish Ministry of Culture and Tourism. The excavation results have shed important new light on the cult of Jupiter Dolichenus, a god widely worshipped across the Roman Empire, and its origin within the Iron Age, when a first temple was constructed on Dülük Baba Tepesi. The sculptural and epigraphical material of the Graeco-Roman phase, which has been collected across fifteen years of research, is presented here for the first time. Beyond the finds from the excavations, the catalogue includes a few pieces that are already known, which can be attributed to the sanctuary and for which new interpretations are offered.
