Sky father in the context of "Anu"

In ancient Roman religion and mythology, Jupiter (Latin: Iūpiter or Iuppiter, from Proto-Italic *djous "day, sky" + *patēr "father", thus "sky father" Greek: Δίας or Ζεύς), also known as Jove (nom. and gen. Iovis [ˈjɔwɪs]), is the god of the sky and thunder, and king of the gods. Jupiter was the chief deity of Roman state religion throughout the Republican and Imperial eras, until Christianity became the dominant religion of the Empire. In Roman mythology, he negotiates with Numa Pompilius, the second king of Rome, to establish principles of Roman religion such as offering, or sacrifice.

Jupiter is thought to have originated as a sky god. His identifying implement is the thunderbolt and his primary sacred animal is the eagle, which held precedence over other birds in the taking of auspices and became one of the most common symbols of the Roman army (see Aquila). The two emblems were often combined to represent the god in the form of an eagle holding in its claws a thunderbolt, frequently seen on Greek and Roman coins. As the sky god, he was a divine witness to oaths, the sacred trust on which justice and good government depend. Many of his functions were focused on the Capitoline Hill, where the citadel was located. In the Capitoline Triad, he was the central guardian of the state with Juno and Minerva. His sacred tree was the oak.

Zeus (/zjuːs/, Ancient Greek: Ζεύς) is the chief deity of the Greek pantheon. He is a sky and thunder god in ancient Greek religion and mythology, who rules as king of the gods on Mount Olympus.

Zeus is the child of Cronus and Rhea, the youngest of his siblings to be born, though sometimes reckoned the eldest as the others required disgorging from Cronus's stomach. In most traditions, he is married to Hera, by whom he is usually said to have fathered Ares, Eileithyia, Hebe, and Hephaestus. At the oracle of Dodona, his consort was said to be Dione, by whom the Iliad states that he fathered Aphrodite. According to the Theogony, Zeus's first wife was Metis, by whom he had Athena. Zeus was also infamous for his erotic escapades. These resulted in many divine and heroic offspring, including Apollo, Artemis, Hermes, Persephone, Dionysus, Perseus, Heracles, Helen of Troy, Minos, and the Muses.

The Statue of Zeus at Olympia was a giant seated figure, about 12.4 m (41 ft) tall, made by the Greek sculptor Phidias around 435 BC at the sanctuary of Olympia, Greece, and erected in the Temple of Zeus there. Zeus is the sky and thunder god in ancient Greek religion, who rules as king of the gods on Mount Olympus.

The statue was a chryselephantine sculpture of ivory plates and gold panels on a wooden framework. Zeus sat on a painted cedarwood throne ornamented with ebony, ivory, gold, and precious stones. It was one of the Seven Wonders of the Ancient World.

*Dyḗus (lit. 'daylight'), also *Dyḗus ph₂tḗr (lit. 'father daylight'), is the reconstructed name of the daylight-sky god in Proto-Indo-European mythology. *Dyēus was conceived as a divine personification of the bright sky of the day and the seat of the gods, the *deywṓs. Associated with the vast diurnal sky and with the fertile rains, *Dyēus was often paired with *Dʰéǵʰōm, the Earth Mother, in a relationship of union and contrast.

While its existence is not directly attested by archaeological or written materials, *Dyēus is considered by scholars the most securely reconstructed deity of the Indo-European pantheon, as identical formulas referring to him can be found among the subsequent Indo-European languages and myths of the Vedic Indo-Aryans, Latins, Greeks, Phrygians, Messapians, Thracians, Illyrians, Albanians and Hittites.

A sky deity is a deity associated with the sky, and are a common feature of polytheistic religions. The sky often has great religious significance.

The daytime sky deities are typically distinct from the nighttime ones. Stith Thompson's Motif-Index of Folk-Literature reflects this by separating the category of "Sky-god" (A210) from that of "Star-god" (A250). In mythology, nighttime gods are usually known as night deities and gods of stars simply as star gods. Both of these categories are included here since they relate to the sky. Luminary deities are included as well since the sun and moon are located in the sky. Some religions may also have a deity or personification of the day, distinct from the god of the day lit sky, to complement the deity or personification of the night.

As polytheistic systems evolve, there is a tendency for one deity to achieve preeminence as king of the gods, for example by being their (sky) father. This tendency can parallel the growth of hierarchical systems of political power in which a monarch eventually comes to assume ultimate authority for human affairs. Other gods come to serve in a Divine Council or pantheon; such subsidiary courtier-deities are usually linked by family ties from the union of a single husband or wife, or else from an androgynous divinity who is responsible for the creation.

Historically, subsequent social events, such as invasions or shifts in power structures, can cause the previous king of the gods to be displaced by a new divinity, who assumes the displaced god's attributes and functions. Frequently the king of the gods has at least one wife who is the queen of the gods.
