Sol (Roman mythology) in the context of "Solar deity"

In ancient Greek religion and mythology, Helios (/ˈhiːliəs, -ɒs/; Ancient Greek: Ἥλιος pronounced [hɛ̌ːlios], lit. 'Sun'; Homeric Greek: Ἠέλιος) is the god who personifies the Sun. His name is also Latinized as Helius, and he is often given the epithets Hyperion ("the one above") and Phaethon ("the shining"). Helios is often depicted in art with a radiant crown and driving a horse-drawn chariot through the sky. He was a guardian of oaths and also the god of sight. Though Helios was a relatively minor deity in Classical Greece, his worship grew more prominent in late antiquity thanks to his identification with several major solar divinities of the Roman period, particularly Apollo and Sol. The Roman Emperor Julian made Helios the central divinity of his short-lived revival of traditional Roman religious practices in the 4th century AD.

Helios figures prominently in several works of Greek mythology, poetry, and literature, in which he is often described as the son of the Titans Hyperion and Theia and brother of the goddesses Selene (the Moon) and Eos (the Dawn). Helios's most notable role in Greek mythology is the story of his mortal son Phaethon. In the Homeric epics, his most notable role is the one he plays in the Odyssey, where Odysseus's men despite his warnings impiously kill and eat Helios's sacred cattle that the god kept at Thrinacia, his sacred island. Once informed of their misdeed, Helios, in wrath, asks Zeus to punish those who wronged him, and Zeus, agreeing, strikes their ship with a thunderbolt, killing everyone except Odysseus himself, the only one who had not harmed the cattle and was allowed to live.

In classical Latin, the epithet Indiges, singular in form, is applied to Sol (Sol Indiges) and to Jupiter of Lavinium, later identified with Aeneas. One theory holds that it means the "speaker within", and stems from before the recognition of divine persons. Another, which the Oxford Classical Dictionary holds more likely, is that it means "invoked" in the sense of "pointing at", as in the related word indigitamenta.

In Augustan literature, the di indigites are often associated with di patrii and appear in lists of local divinities (that is, divinities particular to a place). Servius noted that Praeneste had its own indigetes.

In Sabine and ancient Roman religion and myth, Luna (Latin: Lūna [ˈluːna]) is the divine embodiment of the Moon. She is often presented as the female complement of the Sun, Sol, conceived of as a god. Luna is also sometimes represented as an aspect of the Roman triple goddess (diva triformis), along with Diana and either Proserpina or Hecate. Luna is not always a distinct goddess, but sometimes rather an epithet that specializes a goddess, since both Diana and Juno are identified as moon goddesses.

In Roman art, Luna attributes are the crescent moon plus the two-yoke chariot (biga). In the Carmen Saeculare, performed in 17 BC, Horace invokes her as the "two-horned queen of the stars" (siderum regina bicornis), bidding her to listen to the girls singing as Apollo listens to the boys.

Sol Invictus (Classical Latin: [ˈsoːɫ ɪnˈwɪktʊs], "Invincible Sun" or "Unconquered Sun") was the official sun god of the late Roman Empire and a later aspect of, or replacement for, the old Latin god Sol. The emperor Aurelian revived his cult in 274 AD and promoted Sol Invictus as the chief god of the empire. From Aurelian onward, Sol Invictus often appeared on imperial coinage, usually shown wearing a sun crown and driving a horse-drawn chariot through the sky. His prominence lasted until the emperor Constantine I legalized Christianity and restricted paganism. The last known inscription referring to Sol Invictus dates to AD 387, although there were enough devotees in the fifth century that the Christian theologian Augustine found it necessary to preach against them.

In recent years, the scholarly community has become divided on Sol between traditionalists and a growing group of revisionists. In the traditional view, Sol Invictus was the second of two different sun gods in Rome. The first of these, Sol Indiges, or Sol, was believed to be an early Roman god of minor importance whose cult had petered out by the first century AD. Sol Invictus, on the other hand, was believed to be a Syrian sun god whose cult was first promoted in Rome under Elagabalus, without success. Some fifty years later, in 274 AD, Aurelian established the cult of Sol Invictus as an official religion. There has never been consensus on which Syrian sun god he might have been: some scholars opted for the sky god of Emesa, Elagabal, while others preferred Malakbel of Palmyra. In the revisionist view, there was only one cult of Sol in Rome, continuous from the monarchy to the end of antiquity. There were at least three temples of Sol in Rome, all active during the Empire and all dating from the earlier Republic.
