Orion
Ὠρίων
The giant hunter stung to death by a scorpion and set among the stars.
In the best-known version, he boasted he would kill every beast on earth — so Gaia sent the scorpion.
In another version it was Artemis who shot him — myths split like this all the time.
Orion and Scorpius sit on opposite sides of the sky: when one rises, the other sets.
