Cronus vs Saturn

Is Saturn the same as Cronus? In myth, yes — Ovid's Jove is "the Son of Saturn", Juno is "Saturn's daughter", and Saturn's reign is the golden age that Hesiod places under Cronus. In what happened after, no — Hesiod's Cronus is beaten and made to vomit his children; Virgil's Saturn flees Jove to Italy, hides in Latium, gives it laws and becomes the ancestor of the Latin kings.
