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.

Zeus

Cult sites: Temple of Zeus at Olympia; Oracle of Zeus at Dodona; Nemean sanctuary
Festivals: Olympic Games; Diasia; Dipolieia

White bulls and the thunderbolt belong to him. Olympic contest was a sacrifice as much as a race. Dodona spoke through oak and doves. Civic oaths called Zeus Horkios; a perjurer feared the sky more than the court.

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.

Greek Pantheon

Zeus

King of the gods and ruler of Mount Olympus. God of the sky, thunder, and justice. Zeus overthrew his father Cronus to become the supreme deity of the Greek pantheon.

Zeus was the youngest son of the Titans Cronus and Rhea. Cronus, fearing a prophecy that he would be overthrown by his children, swallowed each child at birth. Rhea hid Zeus and gave Cronus a stone wrapped in swaddling clothes instead. Zeus was raised in secret and later forced Cronus to regurgitate his siblings, leading the rebellion against the Titans.

Zeus is the supreme ruler of the gods, the lord of the sky, and the wielder of the thunderbolt. His power is greater than that of all the other gods combined. He presides over the oaths of men and the laws of the universe, ensuring justice and order.
