  "body": "# Dionysus vs Bacchus\n\n## Where they are the same: birth, pirates, Pentheus\n\nHesiod: Semele \"bore him a splendid son, joyous Dionysus, — a mortal woman\nan immortal son. And now they both are gods\" (Theog. 940–942).\nApollodorus adds the trick of Hera, the thunder, and the sixth-month child\nsewn into Zeus's thigh (Apollod. 3.4.3). Ovid tells it of Juno, Jove and\nSemele: \"her mortal form could not endure the shock and she was burned to\nashes in his sight. An unformed babe was rescued from her side, and,\nnurtured in the thigh of Jupiter, completed Nature's time until his\nbirth\" (Met. 3.251–315). The Homeric Hymn's quarrel over the birthplace —\nDracanum, Icarus, Naxos, the Alpheus, Thebes, \"but all these lie\", it\nwas Nysa (HH1 1–9) — is a Greek quarrel the Latin poet skips.\n\nThe pirates are the clearest match in the corpus. In the Hymn, Tyrsenian\npirates bind a youth; \"the bonds would not hold him\"; wine runs through\nthe ship, \"a vine spread out both ways along the top of the sail\", the\ngod becomes a lion, the crew leap overboard \"and were changed into\ndolphins\", and only the helmsman who warned them is spared (HH7 1–59).\nIn Ovid the spared helmsman, Acoetes, tells Pentheus the same story:\nthe ship \"stood still as if a dry dock held it in the sea\", \"twisting ivy\ntangled in the oars\", \"Bacchus in the midst of all stood crowned with\nchaplets of grape-leaves\" among visionary tigers and panthers, and\nMedon's body grew fins (Met. 3.580–691).\n\nPentheus completes the set. Apollodorus: he spied on the Bacchanals and\n\"was torn limb from limb by his mother Agave in a fit of madness\"\n(Apollod. 3.5.2). Ovid's Tiresias tells him in advance: build a temple to\n\"the new god Bacchus\" or be \"torn asunder\", your blood on \"thy frenzied\nmother and her sisters twain\" (Met. 3.509–579).\n\n## Where they differ: the staged frenzy, and the wine on the table\n\nVirgil's one Bacchic scene is a Latin invention. Queen Amata, poisoned by\nAllecto, runs to the woods \"feigning to feel the madness Bacchus loves;\nfor she essays a fiercer crime, by fiercer frenzy moved\" — she hides her\ndaughter from the Trojan bridegroom, cries \"Hail, Bacchus! Thou alone …\nart worthy such a maid\", and the wives of Latium follow her with\nfawn-skins and vine-clad spears (Aen. 7.341–405). The god's rite is a\npretext for war; nothing in the Hymns or Apollodorus uses it that way.\n\nThe Latin name has also become a thing. Dido toasts \"Bacchus, lord of\nmirth\" (Aen. 1.723–756); Evander's table carries \"Ceres and … Bacchus\ngift and toil\" — bread and wine (Aen. 8.175–183). The Hymns keep the\nperson: \"ivy-crowned Dionysus, the loud-crying god, splendid son of Zeus\nand glorious Semele\" (HH26 1–13).\n\n## Criteria\n\n| Criterion | Dionysus | Bacchus |\n|---|---|---|\n| Parentage | Zeus and Semele (Theog. 940–942); thigh-birth (Apollod. 3.4.3) | Jove and Semele; thigh-birth (Met. 3.251–315) |\n| Sphere | Wine, the vine (Apollod. 3.5.1); ecstatic rout (HH26) | Bacchanalian rites, \"pipes and horns … hollow drums\" (Met. 3.509–579) |\n| Chief myth (Greek) | Pirates turned to dolphins (HH7 1–59); Pentheus torn by Agave (Apollod. 3.5.2) | — |\n| Same myth (Latin) | — | Acoetes's pirates (Met. 3.580–691); Pentheus (Met. 3.509–579) |\n| Roman-only cult or title | — | Amata's feigned frenzy in Latium (Aen. 7.341–405) |\n| Where the names differ | Birthplace disputed, fixed at Nysa (HH1 1–9) | \"Bacchus\" = wine (Aen. 8.175–183) |\n\n## The rule of thumb\n\nFor Semele, the pirates and Pentheus, Bacchus is Dionysus. For a Latin\nqueen who fakes his madness, or a cup of him at dinner, the name is\nRoman.",
