Epic of Gilgamesh
The "Epic of Gilgamesh" was discovered by Austen Henry Layard, Hormuzd Rassam, and W. K. Loftus in 1853. The central character of Gilgamesh was initially reintroduced to the world as ""Izdubar"", before the cuneiform logographs in his name could be pronounced accurately. The first modern translation was published in the early 1870s by George Smith. Smith then made further discoveries of texts on his later expeditions, which culminated in his final translation which is given in his book "The Chaldaean Account of Genesis" (1880).
Sumer
A prime example of cuneiform writing would be a lengthy poem that was discovered in the ruins of Uruk. "The Epic of Gilgamesh" was written in the standard Sumerian cuneiform. It tells of a king from the early Dynastic II period named Gilgamesh or "Bilgamesh" in Sumerian. The story is based around the fictional adventures of Gilgamesh and his companion, Enkidu. It was laid out on several clay tablets and is claimed to be the earliest example of a fictional, written piece of literature discovered so far.
