Who is Orion from Sudden Fiction International: Sixty Short-short Stories and what is their importance?

Orion is the product of the urine of three gods in the story bearing his name. He is a boorish and dull hunter who one day happens upon Artemis's camp and eats her goat. That night, when Artemis falls asleep, Orion rapes her. She then proceeds to kill him with a scorpion, and he dies slowly. He passes in the morning, and Artemis buries his body. Orion spends some time in the underworld fighting and crying, but eventually the gods let him go to the stars with his dog.
