The Sumerians, who flourished in Iraq before 4000 BC, were one of the earliest urban civilizations. One of their heroes was Gilgamesh who had, as a companion, a Bigfoot-like creature called Enkidu. The stories of Gilgamesh were put together in the Akkadian language (which succeeded the Sumerian) as an epic. When Enkidu was killed in the epic, Gilgamesh uttered a lament for him.
