  "body": "# Ares vs Mars\n\n## Where they are the same: the net\n\nNobody doubts the equation when reading the story of the adultery.\nHomer's Hephaestus, told by Helius that Ares and Aphrodite are lovers,\nforges \"bonds which might not be broken or loosed\", spreads them about\nthe bed \"fine as spiders' webs\", pretends to leave for Lemnos, and\nreturns to call \"Father Zeus, and ye other blessed gods\" to look at\n\"a laughable matter and a monstrous\" (Od. 8.266–366). Ovid's Vulcan,\ntold by the Sun of \"the loves of Mars and Venus\", files \"nets invisible,\nfilmy of mesh and airy as the thread of insect-web\", and \"opened wide the\nfolding ivory doors and called the Gods, to witness\" (Met. 4.167–189).\nThe Latin poet is translating; even the joke that the lighter gods wished\nthemselves in the same disgrace is Homer's.\n\nThe parentage travels too: Ares is Hera's son by Zeus in Hesiod\n(Theog. 921–923) and Apollodorus (Apollod. 1.3.1), and Ovid's Mars speaks\nto Jupiter as a son to \"the father of gods and men\" (Met. 14.772–828).\n\n## Where they differ: the founder and the Gates\n\nHomer's Zeus, when Ares comes whining from the battlefield, tells him:\n\"Most hateful to me art thou of all gods that hold Olympus, for ever is\nstrife dear to thee and wars and fightings\" (Il. 5.888–898). The Homeric\nHymn to Ares asks the god for the strength to avoid \"the ways of\nblood-curdling strife\" (HH8 10–17). Ares is honoured for what he can\nwithhold.\n\nMars is honoured for what he gives: Rome. Livy opens his history by\nconceding that Rome \"represent[s] Mars as her own and her founder's\nfather\" (Livy 1.0.7–8), and tells how the Vestal Rea Silvia \"named Mars\nas their father\" of the twins (Livy 1.4.2); Virgil's Jupiter prophesies\n\"a priestess queen, by Mars conceiving\" (Aen. 1.254–296). Ovid then has\nMars claim Jupiter's promise and carry Romulus to heaven as Quirinus\n(Met. 14.772–828). No Greek text makes Ares the father of a city.\n\nThe cult is Roman through and through. Numa gave Mars a Flamen and\n\"twelve Salii for Mars Gradivus\", who marched through the City with the\ntwelve Ancilia \"singing hymns accompanied by a solemn dance in triple\ntime\" (Livy 1.20.2–4). Virgil describes the \"Twin Gates of War … to Mars'\nfierce godhead vowed\", shut with a hundred brass bars and opened by the\nconsul when the senate votes war — a custom \"wide-ruling Rome keeps to\nthis day\" (Aen. 7.601–622).\n\n## Criteria\n\n| Criterion | Ares | Mars |\n|---|---|---|\n| Parentage | Zeus and Hera (Theog. 921–923; Apollod. 1.3.1) | Son of Jupiter (Met. 14.772–828) |\n| Sphere | War, \"strife … dear to thee\" (Il. 5.888–898); \"father of warlike Victory\" (HH8 1–4) | War; \"the might of Mars\" that Rome stirs (Aen. 7.601–622) |\n| Chief myth (Greek) | Caught with Aphrodite in Hephaestus's bonds (Od. 8.266–366) | — |\n| Same myth (Latin) | — | Caught with Venus in Vulcan's nets (Met. 4.167–189) |\n| Roman-only cult or title | — | Father of Romulus (Livy 1.4.2); Gradivus and the Salii (Livy 1.20.4); Gates of War (Aen. 7.601–622) |\n| Where the names differ | \"Sacker of towns\" (Theog. 936) — feared | \"Mars … her founder's father\" (Livy 1.0.8) — claimed |\n\n## The rule of thumb\n\nIn the bedroom of Vulcan, Mars is Ares. In the Forum, at the Gates of\nWar, and in the genealogy of Romulus, he is a god the Greeks never had.",
