sea,\u00a0and\u00a0Gaia,\u00a0Mother Earth.\u00a0He had\u00a0an extraordinary beauty and\u00a0grew so much\u00a0that became\u00a0a genuine\u00a0giant.\u00a0So enormous\u00a0he was\u00a0he could walk\u00a0along the bottom\u00a0of the deep sea\u00a0waters\u00a0without ever\u00a0cover\u00a0him\u00a0from the shoulders up.<br \/>\nAfter many adventures, Orion\u00a0went to\u00a0the island of Chios, where\u00a0soon\u00a0later\u00a0fell in love with\u00a0Merope,\u00a0the daughter of King\u00a0Oenopion.\u00a0Such was his\u00a0love for her\u00a0that\u00a0sought her in marriage.\u00a0Oenopion\u00a0consented,\u00a0but first\u00a0demanded\u00a0the giant\u00a0to prove his\u00a0courageperforming a\u00a0difficult mission.\u00a0Orion\u00a0would have to\u00a0kill\u00a0a large number of\u00a0pests\u00a0that were causing\u00a0huge losses\u00a0to crops\u00a0on the island.\u00a0When he had\u00a0exterminated\u00a0all the\u00a0vermin,\u00a0the monarch\u00a0refused to\u00a0keep his promise.<\/p>\n<p>Orion\u00a0tried to\u00a0take revenge on\u00a0Oenopion,\u00a0but could not find him\u00a0because\u00a0he took refuge\u00a0in a subterranean chamber\u00a0so convoluted,that it was practically\u00a0Inscrutable.\u00a0Then, Orion\u00a0set up\u00a0even more\u00a0in anger\u00a0and,\u00a0in rage,\u00a0he felt like\u00a0killing with his\u00a0infallible\u00a0arrows and\u00a0mercilessly\u00a0all the animals\u00a0that\u00a0were\u00a0going out to meet, whether\u00a0gentle\u00a0or\u00a0fierce animals\u00a0and innocent\u00a0creatures.\u00a0Such was\u00a0the number\u00a0of casualties he\u00a0had caused\u00a0already\u00a0that his mother\u00a0Gea\u00a0had to intervene\u00a0asking, without success,\u00a0that he was\u00a0kind\u00a0and thoughtful.\u00a0Orion\u00a0ignored\u00a0the words of his\u00a0mother\u00a0and sticked\u00a0to his guns, despite\u00a0the repeated warnings from\u00a0Gea.<br \/>\nOne day, when\u00a0the proud\u00a0giant\u00a0was meeting\u00a0with friends,\u00a0conceited\u00a0that neither\u00a0tigers\u00a0or\u00a0panthers,\u00a0or even\u00a0lions or\u00a0snakes\u00a0were able to produce\u00a0any\u00a0awe, overwhelmed\u00a0the patience of his\u00a0mother, who\u00a0sent a\u00a0very poisonous\u00a0scorpion.\u00a0Orion,\u00a0when he saw it,was unable to contain his\u00a0ironic\u00a0smile at\u00a0the ridiculousness of\u00a0this\u00a0insignificant\u00a0adversary\u00a0sent by\u00a0Gaia.<br \/>\n<a

to\u00a0take avenge on\u00a0his mother\u00a0Earth (Gaia).<br \/>\nThe god\u00a0was condescending\u00a0with Orion and\u00a0his supplications\u00a0were attended.\u00a0The earth\u00a0trembled,\u00a0and since then\u00a0it has been doing\u00a0to this day\u00a0every time\u00a0Orion\u00a0has been seen\u00a0above the firmament, as he\u00a0has always\u00a0brought\u00a0the wind, the cold, the storms, the ice, the snow\u00a0and\u00a0the frost\u00a0which\u00a0are\u00a0so abundant\u00a0on Earth\u00a0in winter, coinciding\u00a0with the arrival\u00a0of this constellation.<br \/>\nZeus\u00a0was also responsible\u00a0of placing\u00a0the Scorpion\u00a0(Scorpius) in\u00a0the sky, but\u00a0was careful to\u00a0place it\u00a0as far away from\u00a0the giant\u00a0so they would never\u00a0ever
