Use of literary devices
Not only is The Epic of Gilgamesh world’s first piece of classic literature, but it’s also one of the first known literary works that masterfully uses literary devices. For instance, it’s the first ever work to be written in the past tense third person PoV. The masterful use of irony as a literary device is particularly clear in the second part of the Epic that tells the tale of Gilgamesh’s obsession. Symbolism is also quite prominent, one particular example of it being religious symbols.
Foreshadowing, which is a dramatic plot device hinting at what’s to come, is perhaps the literary device that was used the most in the Epic by means of the characters’ dreams and other instances.
