  "body": "# Zeus vs Jupiter\n\nThe question \"is Jupiter just the Roman Zeus?\" has two honest answers,\nand which one is right depends on whether you are asking about stories or\nabout religion.\n\n## Where they are the same: the stories\n\nOvid opens the *Metamorphoses* with the council of the gods after Lycaon's\ncrime. Its president is \"the Son of Saturn\", \"the Thunder-bolt Controller\",\nwho decides to drown mankind (Met. 1.163–252). Every element of that\nfigure is Greek: the parentage is Hesiod's (Theog. 453–467), the thunderbolt\nis the gift of the freed Cyclopes (Theog. 501–506), the sovereignty over\nthe sky is the lot Homer describes (Il. 15.187–193). Ovid simply says it\nin Latin. The same is true of Jupiter's loves, his war with the giants, his\npunishment of Prometheus: the Roman poets did not invent a mythology for\nJupiter; they adopted one.\n\n## Where they differ: the cult\n\nLivy's Jupiter is not a character in stories but the god of a city. The\nfirst temple in Rome is his — Jupiter Feretrius, where Romulus hangs the\nspoils of a slain king (Livy 1.10.5–7). The epithet Stator comes from a\nbattlefield vow, when Romulus begs the \"Father of gods and men\" to stop a\nrout (Livy 1.12.4–7). The Capitoline temple, begun by Tarquin, becomes the\ncentre of Roman religion, and even its omens are about the future of the\nempire (Livy 1.55.1–4). Virgil then writes the doctrine into the epic:\nJupiter promises Venus that the Romans will have \"empire without end\"\n(Aen. 1.278–279). Hesiod's Zeus does nothing of the kind. He reigns because\nthe other gods asked him to after the Titanomachy (Theog. 881–885), and\nthe Greeks had no single city for him to guarantee.\n\n## Criteria\n\n| Criterion | Zeus | Jupiter |\n|---|---|---|\n| Parentage | Cronus and Rhea (Theog. 453–467) | Saturn (\"the Son of Saturn\", Met. 1.163) |\n| Weapon | Thunderbolt from the Cyclopes (Theog. 501–506) | Thunderbolt (\"Thunder-bolt Controller\", Met. 1.261) |\n| Basis of rule | Acclaimed by the gods after the Titanomachy (Theog. 881–885) | Guarantor of Rome, \"empire without end\" (Aen. 1.278–279) |\n| Cult titles in the sources here | Olympian, aegis-holder (Theog., HH23) | Feretrius, Stator, Optimus Maximus (Livy 1.10, 1.12) |\n| First temple | — | The first temple dedicated in Rome (Livy 1.10.7) |\n\n## The rule of thumb\n\nFor any myth, \"Jupiter\" and \"Zeus\" are the same answer. For any question\nabout Roman religion — temples, vows, titles, the state — \"Jupiter\" is not\na translation of anything.",
