The Epic of Gilgamesh was a series of ancient Greek epics that told the story of Gilgamesh, the hero of ancient Greek mythology. The formation of epics can be traced back to the 5th century B.C., when ancient Greek civilization was in its golden age. In the process of the formation of the epic, the original version can be traced back to the 5th century B.C. during the period of Agamemnon. It was said that Agamemnon had written some simple poems with a poet, which described the heroic deeds of ancient Greek mythology. Later, these poems were passed down and became the earliest Epic of Gilgamesh. As time passed, the content of the epic gradually became richer and more myths and legends were added. In the 4th century B.C., the establishment of democratic politics in Athens made the spread of epics more developed. From the 4th to the 3rd century B.C., many ancient Greek poets and singers constantly revised and supplemented the epic to make its content more complete and rich. Finally, in the 3rd century B.C., Achilles, Iphilus, and others further perfected the epic and made it a complete epic. The Epic of Gilgamesh became an important part of ancient Greek culture and a classic in ancient Greek literature.
