Jinn

The jinn (Arabic: الجن‎ al-jinn, singular الجني al-jinnī; also spelled djinn), or genies, are spiritual creatures mentioned in the Qur'an and other Islamic texts who inhabit an unseen world in dimensions beyond the visible universe of humans. Together, the jinn, humans and angels make up the three sapientcreations of God. The Qur'an mentions that the jinn are made of a smokeless and "scorching fire", but also physical in nature, being able to interact physically with people and objects and likewise be acted upon. Like human beings, the jinn can also be good, evil, or neutrally benevolent and hence have freewill like humans and unlike angels. The jinn are mentioned frequently in the Qurʾan, and the 72nd surah is titled Sūrat al-Jinn.

Janus

In ancient Roman religion and myth, Janus (Latin: Ianus) is the god of beginnings and transitions, thence also of gates, doors, passages, endings and time. He is usually depicted as having two faces, since he looks to the future and to the past. The Romans named the month of January (Ianuarius) in his honor.

Janus presided over the beginning and ending of conflict, and hence war and peace. The doors of his temple were open in time of war, and closed to mark the peace. As a god of transitions, he had functions pertaining to birth and to journeys and exchange, and in his association with Portunus, a similar harbor and gateway god, he was concerned with travelling, trading and shipping.

Janus had no flamen or specialized priest (sacerdos) assigned to him, but the King of the Sacred Rites (rex sacrorum) himself carried out his ceremonies. Janus had an ubiquitous presence in religious ceremonies throughout the year, and was ritually invoked at the beginning of each one, regardless of the main deity honored on any particular occasion.

The ancient Greeks had no equivalent to Janus, whom the Romans claimed as distinctively their own. Modern scholars, however, have identified analogous figures in the pantheons of the Near East. His name in Greek is 'Ιανός (Ianós).

Juno

Juno (Latin: Iūno [ˈjuːno]) is an ancient Roman goddess, the protector and special counselor of the state. She is a daughter of Saturn and sister (but also the wife) of the chief god Jupiter and the mother of Mars and Vulcan. Juno also looked after the women of Rome. Her Greek equivalent is Hera, her Etruscan counterpart is Uni. As the patron goddess of Rome and the Roman Empire, Juno was called Regina ("queen") and, together with Jupiter and Minerva, was worshipped as a triad on the Capitol (Juno Capitolina) in Rome.

Juno's own warlike aspect among the Romans is apparent in her attire. She often appeared sitting pictured with a peacock armed and wearing a goatskin cloak. The traditional depiction of this warlike aspect was assimilated from the Greek goddess Hera, whose goatskin was called the 'aegis'.

Jupiter

In ancient Roman religion and myth, Jupiter (Latin: Iuppiter) or Jove is the king of the gods and the god of sky and thunder. 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 sacrifice.

Jupiter is usually 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 ("Capitol Hill"), where the citadel was located. He was the chief deity of the early Capitoline Triad with Mars and Quirinus. In the later Capitoline Triad, he was the central guardian of the state with Juno and Minerva. His sacred tree was the oak.

The Romans regarded Jupiter as the equivalent of Greek Zeus, and in Latin literature and Roman art, the myths and iconography of Zeus are adapted under the name Iuppiter. In the Greek-influenced tradition, Jupiter was the brother of Neptune and Pluto. Each presided over one of the three realms of the universe: sky, the waters, and the underworld. The Italic Diespiter was also a sky god who manifested himself in the daylight, usually but not always identified with Jupiter. Tinia is usually regarded as his Etruscan counterpart.
