Jupiter
Also called Iuppiter, Jove, Zeus (Greek) · also recorded as Diespiter, Jupiter (mythology), Ioue, Juppiter, Dju Pater (per Wikidata)
Sky-father and state god of Rome, identified with Zeus by the *interpretatio romana* — the ancient world's official policy of treating foreign gods as one's own under different names.
Deep source base
Rome's habit of equating gods across cultures is the practice modern comparative work inherited. Tacitus identifies Germanic Wodan as Mercury; Caesar names the Gaulish gods entirely in Roman terms. The method assumes divine functions are universal and only the names are local — a generous assumption compared to the Christian alternative, which was to treat every foreign god as a demon. Both are systems for handling other people's gods; they simply differ on whether the neighbours are worshipping the same powers or the wrong ones.

Where it was actually worshipped
The Capitoline, at the temple of Jupiter Optimus Maximus — where consuls sacrificed on taking office and triumphs ended.
A figure with temples and a figure that only ever existed on a page are different kinds of thing, and the difference is easy to lose once both are entries in a list.

When these texts were written
Each dot is one of the 4 texts that names Jupiter, placed at that text's approximate date.
A wide spread means the figure was carried across many centuries and traditions; a tight cluster means a single period produced the whole record.

Where the texts differ
- Name: given as Zeus, Jupiter, Jove
Takes the sky in the division of the cosmos and rules by the thunderbolt.
The god of the Roman state doctrine: he sets out the empire without end, restrains the other gods, and is the guarantor of fate rather than its author. Beside Ovid's philanderer, the corpus holds two Latin Jupiters written a generation apart — one official, one literary — and the distance between them is the point.
Convening the gods in council like a Roman senate and putting the destruction of mankind to them as a motion, then sending the flood. Ovid's Jupiter is a magistrate with a temper and an unlimited appetite, and the poem's habit of describing his affairs as legal problems is exactly what makes him usable to later Christian allegory as a figure of misused authority.
Prosecuted rather than described. Augustine works through Varro's theology to show that the chief god of Rome is either a name for the world, in which case the cult is philosophy misfiled, or a person who behaved as the poets say, in which case the honours are obscene. Either way the conclusion is the one this site tracks: the god is a demon, and the empire has been sacrificing to it.

If Jupiter is what you came for, these are next
Chosen by proximity rather than by popularity: the same pantheon first, then the same rank, then the same kind of figure.
Saturn
God of the Golden Age · Roman
Deposed father of Jupiter. His December festival inverted the social order for a week, and his planet later became the astrological signature of melancholy and malice.
Mars
God of War and the Fields · Roman
Father of Romulus and second only to Jupiter in the state cult — an agricultural god as much as a martial one, and not simply the Greek Ares renamed.
Janus
God of Doorways · Roman
God of thresholds with no Greek equivalent — the doors of his temple stood open in war and shut in peace, and they were almost never shut.
Pluto
Lord of the Underworld · Roman
The Roman Hades, whose alternative name Orcus survives in 'ogre' — and whose realm supplied Christian writers much of their imagery for hell.
Marduk
King of the Gods · Mesopotamian
Splits Tiamat and builds the world from her body, and is voted fifty names and supreme authority for doing it.
Zeus
King of the Gods · Greek
Sky-father and enforcer of oaths, whose name descends from the same Indo-European root as Jupiter and Dyaus.
