In Greek literature he first appears as a great hunter in Homer's epic the Odyssey, where Odysseus sees his shade in the underworld. The bare bones of Orion's story are told by the Hellenistic and Roman collectors of myths, but there is no extant literary version of his adventures comparable, for example, to that of Jason in Apollonius of Rhodes'.
Orion served several roles in ancient Greek culture. The story of the adventures of Orion, the hunter, is the one on which we have the most evidence; he is also the personification of the constellation of the same name; he was venerated as a hero, in the Greek sense, in the region of Boeotia; and there is one etiological passage which says that Orion was responsible for the present shape of the Strait of Sicily.
The legend of Orion was first told in full in a lost work by Hesiod. According to this version, Orion was likely the son of the sea-god Poseidon and Euryale, daughter of Minos, King of Crete. Orion could walk on the waves because of his father; he walked to the island of Chios where he got drunk and attacked Merope, daughter of Oenopion, the ruler there. In vengeance, Oenopion blinded Orion and drove him away. Orion stumbled to Lemnos where Hephaestus told his servant, Cedalion, to guide Orion to the uttermost East where Helios, the Sun, healed him. Orion returned to Chios to punish Oenopion, but the king hid away underground and escaped Orion's wrath. Orion's next journey took him to Crete where he hunted with the goddess Artemis and her mother Leto, and in the course of the hunt, threatened to kill every beast on Earth. Mother Earth objected and sent a giant scorpion to kill Orion. The creature succeeded, and after his death, the goddesses asked Zeus to place Orion among the constellations. Zeus consented and, as a memorial to the hero's death, added the Scorpion to the heavens as well More on Orion
