The peak of Bear Mountain on the Kyzikos (Cyzicus) Peninsula.
Entering the Propontis1 on their Quest for the Golden Fleece, the Argonauts made landfall on the Plain of Adrasteia (Adrastia). At dawn, Ieson (Jason) ascended Mount Dindymon to get a view of the surrounding land and sea. The natives of the area, generally referred to as Earthborn, started throwing boulders into the narrow outlet to the harbor where the Argonauts had moored the Argo. Herakles (Heracles) initiated an attack on the Earthborn savages and forced them to retreat.
Storm winds would not permit the Argo to go to sea. Prophetic signs indicated that Ieson should ascend Mount Dindymon again and propitiate the Mother of the Gods (presumably the Olympian goddess, Rhea, known locally as Kybele (Cybele). An altar was built and appropriate sacrifices were made. The goddess permitted Ieson and the Argonauts to continue their mission. This would have been circa 1300 BCE, i.e. one generation before the Trojan War.
