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.

Vesta

Cult sites
Aedes Vestae in the Forum, a round shrine with no cult statue in early form; House of the Vestals beside the temple
Festivals
Vestalia (7–15 June)

Six Vestal Virgins kept the fire and the store of sacred objects, including the Palladium in later telling. Blood sacrifice did not belong inside her round temple. In June the inner store was opened to matrons, who walked barefoot. If the fire went out, it was a public emergency.

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

Vesta

Goddess of the hearth, home, and family. Her sacred fire in the Forum Romanum symbolized Rome's eternal life. Served by the Vestal Virgins, priestesses who tended her sacred flame.

Vesta corresponds to Greek Hestia. Her worship was fundamental to Roman identity - the sacred fire in her temple represented Rome itself and could never be allowed to go out.

Vesta is the hearth, and in Rome the hearth that matters most burns in the Forum. The circular temple of Vesta held a fire that was not supposed to go out. The **Vestal Virgins** tended it, kept wills and treaties, and guarded sacred objects including, in legend, the Palladium. Their legal standing was unique: they could own property, make a will, and free a condemned prisoner by meeting him on the street.

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.
