The seals and sealing of the Dilmun Culture represent one of the most understudied glyptic traditions of the old world. Based on the extant data from the Early Dilmun period (ca. 2250–1650 BCE) the present contribution provides an introduction to the all-pervasive “Gulf” and “Dilmun Type” stamp seals and evaluates the range of their chronological and geographical distribution. Above all, Bronze Age Dilmun is seen as a key context for understanding the sealing traditions of the Old World because it represents a melting pot in which hybrid forms of glyptic art developed under the influence of her major trade partners in the Indus Valley, Babylonia, and beyond. In the present study, rectangular Dilmun seals and cylinder seals carved in the Dilmun style are investigated as cardinal examples in Dilmun art of such creative translations. The study additionally introduces evidence that applies to the symbolic and practical function of the seals as bureaucratic devices in an ideological and administrative system. The latter includes impression on sealings and cuneiform tablets but also addresses a small group of so-called tokens stamped with Dilmun-related seals, and sealing symbolism expressed on pottery vessels.
