A radiant or radiate crown, also known as a solar crown, sun crown, Eastern crown, or tyrant's crown, is a crown, wreath, diadem, or other headgear symbolizing the Sun or more generally powers associated with the Sun. It comprises a number of narrowing bands going outwards from the wearer's head, to represent the rays of the Sun. These may be represented either as flat, on the same plane as the circlet of the crown, or rising at right angles to it.
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.
Barbarous radiates are imitations of the antoninianus, a type of coin issued during the Roman Empire, which are so named due to their crude style and prominent radiant crown worn by the emperor.
Barbarous radiates were issued privately, primarily during the Crisis of the Third Century (c. 259–274 AD) in the western provinces. They are not generally regarded as forgeries, since they were rarely deceptive because they were smaller and cruder than standard issues. They probably functioned as small change.
A solar symbol is a symbol representing the Sun.Common solar symbols include circles (with or without rays), crosses, and spirals.In religious iconography, personifications of the Sun or solar attributes are often indicated by means of a halo or a radiate crown.
When the systematic study of comparative mythology first became popular in the 19th century, scholarly opinion tended to over-interpret historical myths and iconography in terms of "solar symbolism".This was especially the case with Max Müller and his followers beginning in the 1860s in the context of Indo-European studies. Many "solar symbols" claimed in the 19th century, such as the swastika, triskele, Sun cross, etc. have tended to be interpreted more conservatively in scholarship since the later 20th century.
