Rough Notes:

In Greek Mythology, the myths associated with Scorpio (Scorpius) almost invariably also contain a reference to Orion. However, there are two contrasting stories about the two. One tale is that Orion was a giant who was a great hunter and very modest about his amazing skill. One day he fell in love with a princess of an island he was passing, but her father refused to let his daughter go and, thus, was determined to keep Orion away from the princess. The king did so by blinding Orion, thus not letting him hunt and amaze the woman. Orion traveled to the Sun which healed his eyes, and decided to kill the king (who later died during a war) and pursue his hunting. He became great friends with Artemis, who favored Orion greatly for his modesty and superb skill at hunting. One day Apollo was jealous that the two were great friends, and sent a harsh scorpion at him and stung his heel. Artemis, furious with her brother, killed the scorpion and threatened to throw Delphi (Apollo's beloved city) into ruins if he did not apologize, which he hastily did. Zeus decided that Orion should be put in the stars, and the scorpion should always chase him; therefore, the constellation Orion appears in the winter, running away from the constellation of Scorpio which arrives in the summer. - Wikipedia

The Orionids are annual meteor showers that occur at and are named after their radiant, which is located near the constellation Orion. The peak of the Orionid meteor shower occurs around October 21 and range typically from ten to fifteen meteors per hour. The Orionid meteor showers are caused by the well-known HalleyÕs Comet, which was named after the astronomer Edmund Halley and last passed through the inner solar system in 1986 on its 75-to-76-year orbit. The radiant of the Orionids is located between the Orion and Gemini constellations (in the south-eastern sky before dawn, as viewed from mid-northern latitudes).

Orion has important mythological connections with the journey of humanity. Ancient Egyptians claimed their gods came from the Belt Stars of Orion, which were associated with Osiris. Some believe that the connection between Orion and Earth is created by a blueprint or architectural design following the patterns of sacred geometry. This in turn links with ancient astronauts, and the world world energy grid.

Throughout the world there are numerous ancient sites that align with Orion.

• the most famous is the 

Giza Plateau

•  and the layout of the 3 Great Pyramids

the ancient city and pyramid complex of Teotihuacan in central Mexico established in 100 BC.

the layout of the ancient Hopi villages in the American southwest

the Thornborough Henges a neolithic complex in North Yorkshire, England that date from between 3500 and 2500 BC. - this monument complex has been called 'The Stonehenge of the North'.

The constellation has more than one version of a story surrounding it in Greek mythology.

In one version, Artemis, the goddess of hunt and the moon fell in love with Orion. She was so entranced by him, she forgot her divinely duty of illuminating the night sky. Her twin brother Apollo, seeing Orion swimming in the sea, dared his sister to strike what only appeared to be a spot on the waves. Not knowing it was Orion, Artemis shot an arrow and killed him. Later, when she found out what she did, she placed his body among the stars. The grief she felt explains why the moon looks so sad at night.

In a different ending of this myth, Apollo's jealousy led him to summon a giant scorpion, which not even the mighty hunter Orion could defeat, and he was killed by its poisonous sting. In some versions he slays the scorpion just after it stings him, and they die simultaneously. This explains the seasonal alternation of the appearance of the constellations of Orion (October to April) and Scorpius (April to October), which do not appear in the sky together. Legends differ on whether this separation was imposed by the gods so that they would never have to fight again or so that they would be eternally chasing each other.

Sirius, the Dog Star, constitutes Orion's left leg. It is part of Canis Major and has its own mythology. In some myths, it is Orion's hunting dog. By the time of the Roman Empire, Canis Minor was said to be Orion's second child, but the ancient Greeks refer only to one dog.

It may be that the naming of the constellation precedes the mythology in this case. It has been suggested that Orion is named from the Akkadian Uru-anna, the light of heaven, the name then passing into Greek mythology. As such, the myth surrounding Orion may derive simply from the relative positions of the constellations around it in the sky.

In some depictions, Orion appears to be composed of three bodies, having three arms, two divergent legs, and a small central one, as well as the three bodies being bound at the waist. As such, together with other features of the area in the Zodiac sign of Gemini (i.e. the Milky Way, the deserted area now considered as the constellations Camelopardalis and Lynx, and the constellations Gemini, Auriga, and Canis Major), this may be the origin of the myth of the cattle of Geryon, which forms one of The Twelve Labours of Herakles.

In pre-Christian Scandinavia, the "Orion's belt" portion of the constellation was known as Frigg's Distaff (Friggerock) or Freyja's distaff. In Finnish mythology the constellation of Orion is called the scythe of Vainamoinen. The term most likely comes from the fact it can be seen in the sky in early autumn in the Northern Hemisphere, the time of haymaking.

In ancient Aram, the constellation was known as Nephila, Orion's descendants were known as Nephilim.

The constellation is mentioned in Horace's Odes, Homer's Odyssey and Iliad, and Virgil's Aeneid.

The Bible mentions Orion 3 times: Job 9:9, Job 38:31 , and Amos 5:8.

The Seri people of northwestern Mexico call this constellation Hapj (a name denoting a hunter) which consists of three stars: Hap (mule deer), Haamoja (pronghorn), and Mojet (bighorn sheep). Hap is in the middle and has been shot by the hunter; its blood has dripped onto Tiburon Island.

Orion is also important in Australian Aboriginal Astronomy. For example, the Yolngu people of Arnhem Land say that the constellation of Orion, which they call Julpan, is a canoe. They tell the story of two brothers who went fishing, and caught and ate a fish that was forbidden under their law. Seeing this, the Sun sent a waterspout that carried the two brothers and their canoe up into the sky where they became the Orion constellation.

In Indian Mythology, the constellation is known as 'Vyadh', which also means The Hunter.
