How each was worshipped

Jupiter

Cult sites: Temple of Jupiter Optimus Maximus on the Capitoline, shared with Juno and Minerva; Temple of Jupiter Stator near the Forum; Temple of Jupiter Latiaris on the Alban Mount (Latin League)
Festivals: Ides (monthly); Ludi Romani (September); Vinalia

The flamen Dialis kept a life of taboos that marked Jupiter as the state's sky. White cattle went to him. A triumph ended at the Capitoline temple, where the general laid his laurels before Jupiter Optimus Maximus. The Ides belonged to him each month.

Mars

Cult sites: Temple of Mars Ultor in the Forum of Augustus; Altar and later temple in the Campus Martius; Outside the pomerium in early Rome, where an army god belonged
Festivals: Equirria; Quinquatrus (19 March); October Horse; Armilustrium

The Salii danced with the ancilia in March and October. The flamen Martialis kept his cult. The October Horse was a chariot race whose right-hand horse was killed and its head fought over by neighborhoods. Mars is agriculture's guard as much as the legion's.

The two figures

Roman Pantheon

Jupiter

King of the gods and god of sky, lightning, and thunder. Supreme deity of the Roman state religion, protector of Rome and source of divine authority for Roman emperors.

Jupiter corresponds to the Greek Zeus, born to Saturn (Cronus) and Ops (Rhea). He overthrew his father to become king of the gods, establishing divine order and justice.

Jupiter is the chief god of the Roman state, not a renamed Zeus wearing a toga. His oldest title, **Optimus Maximus**, "best and greatest," belongs to the temple on the Capitoline that he shared with Juno and Minerva. Roman magistrates took office under his gaze. Treaties were struck in his name. When lightning struck, the *pontifices* read it as his speech.

Roman Pantheon

Mars

God of war and guardian of Rome. More prominent in Roman religion than his Greek counterpart Ares, Mars was also a god of agriculture and fertility. Father of Romulus and Remus, legendary founders of Rome.

Mars was the son of Jupiter and Juno. He fathered Romulus and Remus with the Vestal Virgin Rhea Silvia, making him the divine ancestor of the Roman people.

Mars is a war god, and he is also something Ares almost never is: an ancestor. With the Vestal **Rhea Silvia** he fathered Romulus and Remus, which makes him divine grandfather of the Roman people. The Campus Martius, the army's field, carried his name. So did the month of March, when campaigning weather returned and the Salii danced with the sacred shields.

About this comparison

Comparisons pair figures that play a similar role across traditions, or that the myths connect within one. A shared role does not, by itself, establish a shared origin.
