Our recent research on the settlement of Ikaros in the Arab/Persian Gulf brings a new contribution to the knowledge of the networks to which the island belonged from the Hellenistic period to the Parthian period: Seleucid, regional or “international”. In particular, the study of the fortifications, which confirms the foundation of the fortress by the Seleucids, highlighted the existence of phases of abandonment which show that the island should then be excluded from the Seleucid kingdom. At the same time, the perennial breeding and consumption of pigs, a practice that we believe to have been introduced on the island by the Seleucids, did not stop even during the phases of absence of this political power. The pottery clearly indicates a coexistence of practices linked to both “Greek” and regional influences.
