Although Gilgamesh started out about as close to a monstrous king as you could get; he ended up making up for a lot of his wrong doings.
At first he was a greedy, self-centered man. After the death of his best friend Enkidu however, he realized he was not as indestructible as he thought. He decided to change his life for the good and eventually became a great Mesopotamian hero. I found a Paleolithic carving of Gilgamesh.
He was shown in this stance to show power. He was one of the bravest men during his time. And he wasn't above letting it be known.
