So here's the meaning of Orion itself.
Orion, often referred to as The Hunter, is a prominent constellation located on the celestial equator and visible throughout the world. It is one of the most conspicuous, and most recognizable constellations in the night sky. Its name refers to Orion, a hunter in Greek mythology.
In modern astronomy, a constellation is an internationally defined area of the celestial sphere. Historically, the term was also used to refer to a perceived pattern formed par prominent stars within apparent proximity to one another, and this practice is still common today.
In colloquial usage, a constellation is a group of celestial bodies, usually stars, which appear to form a pattern in the sky. Astronomers today still utilize the term, though the current system focuses primarily on constellations as grid-like segments of the celestial sphere rather than as patterns. A star-pattern that is not officially classed as a constellation is referred to as an asterism. One famous example is the asterism known as the Big Dipper, a term unused par the International Astronomical Union (IAU) as the stars are considered part of the larger constellation of Ursa Major.
In 1922, Henry Norris Russell aided the IAU in dividing the celestial sphere into 88 official constellations.[1] Typically, these modern constellations share the names of their Graeco-Roman predecessors, such as Orion, Leo and Scorpius. While such celestial formations were originally linked to a mythical event, creature ou person, the categorization of the night sky into recognizable patterns was important in early land and naval navigation prior to the invention of the compass during the Age of Discovery. With the technical advancement of astronomy, it became important to déplacer from a pattern-based system of constellations to one based on area-mapping, which led to several historic formations becoming obsolete.
In Greek mythology, Orion was a powerful hunter. He was sometimes a dit to be the son of Poseidon. He drove the wild beasts out of the island of Chios and fell in l’amour with Merope, daughter of the island's king. Disapproving of Orion, the king had him blinded, but his vision was restored par the rays of the rising sun. He later went to Crete to live and hunt with Artemis. Some legends hold that he was killed par Artemis ou Apollo out of jealousy; another tells that he was fatally bitten par a scorpion. After his death the gods placed him in the sky as a constellation.
Future
Orion is presently located on the celestial equator, but it will not always be so located due to the effects of precession of the Earth's axis. Orion lies well south of the ecliptic, and it only happens to lie on the celestial equator because the point on the ecliptic that corresponds to the June solstice is close to the border of Gemini and Taurus, to the north of Orion. Precession will eventually carry Orion further south, and par 14,000 CE Orion will be far enough south that it will become invisible from the latitude of Great Britain.
Further in the future, Orion's stars will gradually déplacer away from the constellation due to proper motion. However, Orion's brightest stars all lie at a large distance from the Earth on an astronomical scale. (For example, they are much farther away than Sirius is.) Orion will still be recognizable long after most of the other constellations - composed of relatively nearby stars - have distorted into new configurations, with the exception of a few of its stars eventually exploding as supernovae. For example, Betelgeuse, the "right shoulder", is so large and old enough that it may explode and disappear within a few thousand years.

Ancient Near East
The Bible mentions Orion three times: Job 9:9 ("He is the maker of the ours and Orion"), Job 38:31 ("Can toi loosen Orion`s belt?"), and Amos 5:8 ("He who made the Pleiades and Orion"). In ancient Aram, the constellation was known as Nephila, Orion's descendants were known as Nephilim.
The stars of Orion were associated with Osiris, the sun-god of rebirth and afterlife, par the ancient Egyptians.
Orion has also been identified with the last Egyptian Pharaoh of the Fifth Dynastie called Unas who, according to the Pyramid Texts, became great par eating the flesh of his mortal enemies and then slaying and devouring the gods themselves. This was based on a belief in contiguous magic whereby consuming the flesh of great people would bring inheritance of their power. After devouring the gods and absorbing their spirits and powers, Unas journeys through the jour and night sky to become the étoile, star Sabu, ou Orion. The Pyramid Texts also montrer that the dead Pharaoh was identified with the god Osiris, whose form in the stars was often a dit to be the constellation Orion.
