Anecdotes
According to Roman mythology, Jupiter was saved from his father Saturn by his mother Ops, who hid the infant in Crete and offered Saturn a swaddled stone in his place. Saturn, who devoured his children to prevent being overthrown, was thus deceived. Later, Jupiter forced his father to regurgitate his siblings, then dethroned him to rule over the world.
The Temple of Jupiter Optimus Maximus, built on the Capitoline Hill in Rome and dedicated in 509 BC, was the most sacred shrine in the city. Each year, newly elected Roman consuls sacrificed white bulls there to seek divine favor. It was the living heart of Roman civic religion.
During military triumphs, the victorious general ascended the Capitoline dressed in a gold-embroidered toga, carrying an ivory scepter topped with an eagle — the very attributes of Jupiter himself. This ritual served as a reminder that it was Jupiter who granted victory to Rome, and that the general was merely his temporary instrument.
Jupiter was the guardian of oaths and treaties. When the Romans concluded an alliance, the fetial priests invoked Jupiter Fidius and struck a pig with a flint stone, declaring: 'May Jupiter strike Rome as I strike this animal, should she break the treaty.' This solemn formula bound states together by divine word.
When a Roman emperor died, an eagle — Jupiter's sacred bird — was released above the funeral pyre. The Romans believed that the emperor's soul was carried up to the heavens by Jupiter's messenger, which justified the apotheosis, that is, the official deification of deceased emperors.
Primary Sources
Jupiter promises Venus the eternal empire of Rome: 'I set no limits on their power and no end to their time: I have given them empire without end.' He governs all things by his gaze and his will alone.
Jupiter, outraged by the corruption of mankind in the Iron Age, summons the gods in assembly and resolves to destroy the human race by flood: 'This race must be wiped out by extraordinary means — let the earth be submerged on all sides by my waters.'
The ancients wished Jupiter to be the king of all gods and all men, and they proclaimed him father, regarding him as the supreme ruler of the sky and the dispenser of light; hence his name Diespiter, the father of the day.
Romulus, after founding Rome, established the cult of Jupiter Feretrius on the Capitoline Hill and dedicated to him the spolia opima seized from King Acron. This was the first sanctuary erected in the nascent city, a testament to the divine protection granted to Rome.
As long as Jupiter presides over the affairs of men, Rome shall rule the nations. Horace calls upon him: 'Guardian of the Empire, you whom the gods have chosen to watch over Rome, do not let the wicked overturn the order you have founded.'

At the break of day, Jupiter presides from Olympus over the fates of gods and men. He sometimes convenes the deities in solemn assembly to deliberate on the destiny of mortals, listening to the prayers rising from Roman temples alongside the first smoke of morning sacrifices.

As night falls, Jupiter presides over the banquets of the gods on Olympus, surrounded by Juno and the Olympian deities. He receives the hymns of Roman priests completing their rites and ensures that the cosmic order is maintained until the next dawn.
