Orion Will Shrug
when he'll vanish into the Dusk in mid-May His departure doesn't occasion him the same grief that so profoundly affects the rest of us. After all, Orion has been milling about the sky for more than a century of centuries: he loomed high in the firmament when the Stonehenge builders convened their first meetings on the English plain; looked upon the flames and revelry of Rome's Saturnalia festivals; was largely ignored by the Bayeux tapestry weavers; revered by Doctor Faustus; studied by Thomas Jefferson and observed by Harry Potter. And, he lingered about thousands of years before Stonehenge was just a blue print just as he will be traipsing through the heavens centuries after Harry becomes a figure of ancient literature. To Orion, this imminent departure is just the latest go around in an interminable circuit through Earth's skies. (As Orion's stars are quite distant, he is likely poised high above many nearby alien planet scapes, as well.)
Tonight, Orion will lurk low in the western evening sky. One can find the grand hunter on its side, as though in repose, just above the western horizon.

A large rectangle enclosing a diagonal three star belt comprises his main pattern. Two star lines curling out from his northeastern rectangle star, Betelgeuse, form a bronze club. A semi circle of stars surrounding the northwestern rectangle star, Bellatrix, represents a lion skin shield. A faint sword dangles from his belt. A solitary star marks his head.
Mythologically, Orion has assumed various identities: the Egyptian Death God Osiris; the grand Hebrew hunter Nimrod; the Sioux warrior Long Sash; and in some traditions was Feryja, a Nordic Goddess. One will find other Orion incarnations in various African, Asian and other cultural folklore around the world. Since the celestial equator -the projection of Earth's equator onto the sky- passes just above the belt, Orion is wholly visible to more than 99% of the world's population. (Only the chest and shoulder section appear around the North Pole; whereas a South Pole observer sees only the belt and legs.) His widespread visibility. his stark resemblance to a standing human, and his collection of brilliant stars have assured Orion a global fame surpassing that of any other single star pattern.
Of all his other identities, he is now principally known as Orion, considered the greatest hunter in Greco-Roman mythology, superior even to Artemis, Goddess of the hunt and the Moon. One tale portrays Orion as reckless and boastful. So proud was he of his hunting prowess that he openly proclaimed himself capable of slaying any beast, no matter how formidable. Appalled by Orion's impertinent attitude -such irrational arrogance was only deemed proper in Olympus- Artemis deployed Scorpius the Scorpion onto Earth. The Scorpion promptly found Orion and nipped his ankle, killing him instantly. Curiously, Artemis then foisted Orion's spirit into the sky and bejeweled him with bright stars as a tribute to his superb hunting skills. He was perhaps also set into the stars as a warning to other gifted mortals that it is best for one to remain quiet about one's exceptional abilities.
And there he remains on full display as he has for such a long time. We should point out that even Orion is ultimately mortal. His component stars all move through the galaxy in various directions and after tens of thousands of years, the pattern will become noticeably distorted and ultimately unrecognizable. For us mortals, Orion's life is interminable. However, by galactic time periods, Orion is a fleeting configuration: just one of the myriad star patterns through the galaxy that form and dissolve in deep time.
