Final answer:
In the Epic of Gilgamesh, a serpent steals a plant that could grant immortality from the main character, Gilgamesh, who as a result accepts his mortality and returns a wiser king to Uruk.
Step-by-step explanation:
The subject in the question refers to an event in the ancient Mesopotamian narrative, the Epic of Gilgamesh. In this poem, the protagonist Gilgamesh embarks on a quest for immortality after being struck by the fear of death following the passing of his friend Enkidu. During his journey, Gilgamesh ultimately obtains a plant that has the power to grant him eternal life. Unfortunately for Gilgamesh, this plant is stolen by a serpent while he bathes, thus denying him the chance at immortality. As a result of this loss, Gilgamesh becomes resigned to his mortality and returns to his city, Uruk, where he continues to rule as a king who is now wiser and more introspective about the human condition.
