Transference of Sabazios to the Roman world appears to have been mediated in large part through Pergamum. The naturally syncretic approach of Greek religion blurred distinctions. Later Greek writers, like Strabo in the first century CE, linked Sabazios with Zagreus, among Phrygian ministers and attendants of the sacred rites of Rhea and Dionysos. Strabo's Sicilian contemporary, Diodorus Siculus, conflated Sabazios with the secret 'second' Dionysus, born of Zeus and Persephone, a connection that is not borne out by surviving inscriptions, which are entirely to "Zeus Sabazios". The Christian Clement of Alexandria had been informed that the secret mysteries of Sabazius, as practiced among the Romans, involved a serpent, a chthonic creature unconnected with the mounted skygod of Phrygia: God in the bosom' is a countersign of the mysteries of Sabazius to the adepts". Clement reports: "This is a snake, passed through the bosom of the initiates".
