Ancient Greek religion
Syncretism functionalized as an essential feature of Ancient Greek religion. Later on, Hellenism, a consequence of Alexander the Great's belief that he was the son of a god, only to be reinforced upon personally consulting the Oracle of Zeus-Ammon at Siwa in Egypt, itself showed syncretist features, essentially blending Persian, Anatolian, Egyptian (and eventually Etruscan-Roman) elements within Hellenic formulations. After the Hellenization of the Egyptian culture initiated by Ptolemy I Soter, Isis became known as "Queen of Heaven" and worshipped in many aspects and by many names besides that of Hera.
