In ancient Phrygian mythology, Sabazios ('q.v.') was the chief god, a nomadic sky god, probably of Thracian origin, whose cult was subsumed in the 5th century BCE, first by the Greek Zeus, and then identified with the Cretan 'reborn' Dionysus, also known as Zagreos.
In Roman cult, Sabazius became indistinguishable from Bacchus.
