Orpheus[1]https://en.wikipedia.org/wiki/Orpheus (/ˈɔːrfiəs, ˈɔːrfjuːs/; Greek: Ὀρφεύς) was a legendary musician, poet, and prophet in ancient Greek religion and myth.
The major stories about him are centered on his ability to charm all living things and even stones with his music, his attempt to retrieve his wife, Eurydice, from the underworld, and his death at the hands of those who could not hear his divine music.
As an archetype of the inspired singer, Orpheus is one of the most significant figures in the reception of classical mythology in Western culture, portrayed or alluded to in countless forms of art and popular culture including poetry, film, opera, music, and painting.
For the Greeks, Orpheus was a founder and prophet of the so-called “Orphic” mysteries.
He was credited with the composition of the Orphic Hymns, a collection of which only two have survived. Shrines containing purported relics of Orpheus were regarded as oracles.
Some ancient Greek sources note Orpheus’ Thracian origins.
Orpheus,[2]https://www.britannica.com/topic/Orpheus-Greek-mythology ancient Greek legendary hero endowed with superhuman musical skills. He became the patron of a religious movement based on sacred writings said to be his own.
Traditionally, Orpheus was the son of a Muse (probably Calliope, the patron of epic poetry) and Oeagrus, a king of Thrace (other versions give Apollo). According to some legends, Apollo gave Orpheus his first lyre. Orpheus’s singing and playing were so beautiful that animals and even trees and rocks moved about him in dance.
Orpheus joined the expedition of the Argonauts, saving them from the music of the Sirens by playing his own, more powerful music. On his return, he married Eurydice, who was soon killed by a snakebite. Overcome with grief, Orpheus ventured himself to the land of the dead to attempt to bring Eurydice back to life. With his singing and playing he charmed the ferryman Charon and the dog Cerberus, guardians of the River Styx. His music and grief so moved Hades, king of the underworld, that Orpheus was allowed to take Eurydice with him back to the world of life and light. Hades set one condition, however: upon leaving the land of death, both Orpheus and Eurydice were forbidden to look back. The couple climbed up toward the opening into the land of the living, and Orpheus, seeing the Sun again, turned back to share his delight with Eurydice. In that moment, she disappeared. A famous version of the story was related by Virgil in Georgics, Book IV.
